Earth and Space Wrapping Up

To wrap up the semester, I decided to set up a bunch of guest speakers.

First up is a writer for space.com on the latest in astronomy apps, and astronomer -  Mr. Chris Vaughan (@astrogeoguy)  He arrived at the school at 8:15pm and 12+ students came trickling in afterwards.  It was a tough time for the majority of my class as there were many tests and assignments due that particular week.  A definite reason to not run this workshop towards the end of the semester.  Next time I'll change the time of year this occurs.

Nevertheless, we saw the moon in spectacular detail, then Jupiter, Mars, Saturn, and then a whole host of stars came out.  Antares, the "equal to-Mars" star, which twinkled, giving away its star status making it distinguishable from Mars.  We saw Vega, the brightest star in the summer sky.  Other salient and very interesting things in the sky was the ISS and the iridium flash by a satellite.

Second up was Ms. Julie Lum, parent council chair for the past 3 years as well as a geologist + engineer for the Suncor/Shell.  We managed to tag-team this presentation, as I helped convert her quiz into a kahoot.it.  The change from last year's presentation to this year's was impressive as she incorporated videos and presented Shell's vision of clean energy and latest in fracking in an engaging presentation.  It's pretty cool to see a parent council chair who is willing to try teaching.  As a parent of 3, parent council chair, and now a 'teacher', she has put on hats as a parent, administrator, and teacher.

he skillfully guided students through their misconceptions of the universe.  He would take students' inputs and ideas and weigh them by guiding them through logic  - pulling on some of their ideas, like a loose thread, until it came loose.  He followed them through on their misconceptions to point out its weakness from their own logic that he helped guide to eventually crumble their misconceptions.

He arrived early, and I gave him the option of speaking to grade 9s.  He held a Q&A session.  He taught with humility and incredible openness.  The questions that those grade 9s asked (most of which came from my ex-grade 9 math students who I have encouraged to ask questions) were great - how is the universe expanding, how big is the universe, why is it so much harder to breathe as you get higher, how do we measure how big things are, etc.  Again - he has never taught grade 9s, but his ability to take such difficult concepts and simplify it for them was like watching Michaelangelo paint the Sistine Chapel.  He used anecdotes, simple math analogies, and drew upon everyday experiences to satisfy their questions.

He apparently teaches astronomy to humanities students - UT forces humanities students to take a science.  I could see that he used the same tone with my high school students - where every word he used was measured and carefully selected so as to keep his audience engaged no matter how difficult the concept.  I could tell that he used this tone and linguistic style for both the grade 9s and grade 12s as there was one hint where this 'armor' broke - one of my grade 12 students asked how can the universe be simultaneously infinite in size and infinite in mass.  His tone and pacing changed ever so slightly as the question started to enter the realm of math.  He excitedly rattled off the density equation and explained how the beginning of the universe can be infinite (because the universe is anything and everything that will be), but also be small in volume, exploding the density to infinity.

A colleague pointed out that I can do this same process as the professor with my math students - where I can help guide a student to use their own logic to to help them see the error of their own math solution.  And it's true...I can do that because I know the subject matter.  I just don't know my astronomy well enough to get to that level.  So it was spectacular to watch and see this occur for an astronomy course.

His visit, among many things, showed me that I have a long way to go as a teacher.  It was really fun to watch the art of teaching.  Time to get to work!

Character Education - Honesty with Marks

One of the things that I wonder about as a teacher is the relationship between marks and learning. While this debate can run quite deep with some teachers advocating to do-away with marks entirely and others on the opposing spectrum to anything in between.

 I am going to look at this from the student's perspective.  Especially when it comes to grade 12, many students focus solely on mark grabbing and hopefully learning occurs along the way.  I try to emphasize that if students focus on learning as the priority, then the marks will naturally come.

It's just easier, from the student's point of view, to focus on getting marks first which promotes behaviours that I don't consider 'true learning' such as passing around last year's tests, studying at the last second for the short term memory thing, cheating, and memorizing.    

Some will say it's the teachers' fault for setting up this system.  Others' will fault the universities' inability to sort through candidates other than through marks.  It might be a little from column A and a little from column B, and even from an unknown C that I haven't quite considered. 

The beauty of being a teacher is that in many ways, I control the classroom.  In my little world here, I can highlight and contrast the difference between a mark grabbing student and a student that learns for my own students.  

Every year, at the beginning, my students write a diagnostic that does not count for marks.  When I mark it the multiple choice portion, I purposely:

1)  take away a mark that they deserve 

2)  give them an extra mark that they do not deserve

In the end, their mark stays the same.  However, after I take it up the test and show the marking scheme, I go around individually to each student asking how I should change their mark.

I have found in the two years  that I have done this, many students state that their mark goes up by 1, a few ask to bring down their mark by 1, and many so no change.

I then ask the students to reflect on their action.  I cannot judge what they did because I do not know the rationale behind their action but I take the time to highlight the following:

A)  If you asked me to reduce your mark knowing full well you deserve another mark, then you are too hard on yourself.  You deserve another mark, and should ask for it - after all, you got the answer right as well as another question wrong.

B)  If you asked me to increase your mark by 1 or decrease your mark by 1 because you didn't notice the other mistake I made, then you have to pay attention a little more during test takeup.  This is a time to learn from your mistakes, which is quite often the best time to learn.  Be a little more detail oriented and listen carefully for these are important skills in life. 

C)  If you said "no change" because you didn't notice anything wrong, then you are not paying attention whatsoever.  (I may run the risk of an IEP student that has issues with the delivery, but I do make sure to show the multiple choice answers visually and say the answers aloud for each question so that should cover most minor IEPs.)

D)  A few students say "no change" but have already done their self-reflection on what question was actually right and what question was wrong.  This is fine as well.

E)  Each class, there's always one or two students that tell me explicitly that I marked one question right and one question wrong, showing true transparency to me.  This is awesome, and it is something I tell them I try to do for them as a teacher.

F)  This is the last option I go over.  I've learnt to explain this last option gently as a few of my more sensitive students feel guilty even when they didn't do this.  If a student asks for a +1 in marks knowing full well they should have a no mark change, then I ask these students that find themselves in this position to do some deep reflection.  I state: "You have just lied to me about your mark.  What did I do to you in the last week to deserve this?  (hopefully I did nothing wrong in the past week to start the school year off).  You have just inflated your mark to your parents about your mark.  Above all, you're willing to lie to yourself and pat yourself on the back for getting a higher mark than you deserve.  If you're willing to lie to yourself to inflate your mark, lie to me who has done nothing to you, and even your parents on a diagnostic test that doesn't even count for marks - what are you going to do when it comes to money or other situations?

This year, I delivered my speech well.  I returned a test on January 4th, and made a mistake on a multiple choice question.  This is almost 4 months after my little stunt.

Class 1:  I had 7 students come to for a mark increase. I had 8 students come to me for a 1 mark decrease.

Class 2:  I had 8 students come for a mark increase and 7 marks come for a mark decrease. 

As you can see, grade 9s are very receptive to this sort of thing.

When I pull this stunt with my grade 12s, I get into deep debates with my grade 12 students when I ask them these questions.  The one thing they always bring up is that this mark is so small, it doesn't matter.  From their perspective, this if this one mark occurred on a summative assessment, it would help them in their goal to getting into university and it doesn't hurt anyone.  If it doesn't hurt anyone, why not do it?

We then go back and forth about the fact that if you increase your marks unfairly to get into a university program, you're kicking someone else out of the same university program.


I know deep down that the system will have to change to have any permanent effects, but in the end, it's a fun debate and a good exploration on what honesty really means.  I learn much of my students in this little experiment and I'll probably continue to do it. 

Iterations Improving the Proficiency of my 3-Act Math Delivery

NOTE:  This is a late post - supposed to have been published last month but I've only recently found time (during exams) to post it.

For today's lesson, we turned to Dan Meyer’s video question on which cup contained more juice.  Here's my powerpoint that goes with it:  

It is a splendid 3-act problem that inspired some interesting questions.  However, the quality of their questions has decreased since September; the questions had more depth, and their observations keen.  Now, they are just giving me the question that I am looking for.  Wasn’t the whole point to emphasize the questioning to clearly define problems a little more?  It looks like I’ve fallen hard into my habits and have prized THE answer as opposed to prizing the question and problem definition. 

Wow, blogging really forces me to reflect more than usual.  It just dawned on me that the reason why the question quality has been decreasing since September is that I don’t answer all of their questions.  There were so many quality math questions that were generated by the students from the videos in September but I ignored the most quality ones because they would probably take a day to answer. 

I have placed 100% more importance on following my scheduled spiral curriculum than their curiosity. 

Looking back, I should have made more of a compromise, and actually followed through with at least a few of their questions.

It would show a lot more teacher willingness to venture into the unknown and really value their questions.  Following through to try and answer their questions would actually demonstrate how I learn – one of the most important things to model.   Instead, I’ve trampled on their curiosity and lost that opportunity to be a role model of a real learner. I feel really badly now. 

But, can’t be ruminating now, can we?  I’ll just change it for next semester.

So I’ve digressed.  Going back to the 3-act question:

After receiving their questions, I specified the question that we were going to answer today.  Which cup has more, and by how much? 

Here are their guesses as a completion to act 1: 

It’s interesting to see how many of them chose that cup A and cup B had the same amount. 

Nevertheless, act 2 came along, and with those measurements and the conversion ratio the students went about to work. 

After about 15 minutes of discussion and hard work on large whiteboards, the students put their answers on at the front.  Only 10% of them got the right answer:

 The stumbling point for many students was the CONVERSION!  I have to find another way of teaching conversions as I have been repeating it throughout the year and it still hasn't sunk in. 

In truth, the fact that many of my students weren’t able to complete this question in pairs disappointments me. 

I made this question into an entrance card to repeat for tomorrow in hopes that the students will get it during their second try.

I will take it up and repeat a similar question as an assessment on the next Friday. 

Update:  They did very well on their assessment.  I wonder if they’ve gained any ‘permanent’ skills along the way in this process or if they've just memorized the process.  I will only find out later I guess especially with that EQAO coming up soon.  

EQAO - math standardized test - the time is here..

Wow.  We just finished the EQAO and it looks like it's been quite a success.  The students, according to my marking, have scored the highest they ever have compared to the previous two times I've taught the course.  In their feedback of how they felt about writing the EQAO, the students reported a high level of satisfaction upon completing the test.

The success comes as no surprise as I've never had engagement like this before.  However, it just feels pretty good to have this spiral curriculum and 3 act math pay off.

Well, of course, I think in order to really see if all of this did work, I should compare their grade 6 math EQAO marks to their grade 9 EQAO results to see if I really did make a difference.  We'll have to wait until next year for those results.

I'll just have to wait, then.  

Inquiring the Surface Area of a Sphere Through the Peeling of Oranges!

It's getting closer to the winter break, so it was great to have some hands-on activities to add some spice to the classroom for my academics.

It seems like my applied class is getting all the engaging and interesting approaches to math, so this was quite refreshing for myself (and especially these academic kids) to have this tangerine activity to explore the surface area of a sphere.

First thing we did was take a good look at the tangerines and noted its differences from a perfect sphere.  We then went on to talk about how perfect mathematical spheres don't exist in the real world since once one gets into the atomic level, things just aren't continuous.  This sort of statement really bothered some of my students  that one went home and told their parents.

Nevertheless, upon noting the clementines' (lack of) sphere-like properties, we proceeded to take a guess as to its surface area in terms of its radius, and thus area of its 2D ('projection'?)  version.   Each partner made their guess:

Looks like they their estimation skills are almost en par with my applied students' skills which has been honed through the Dan Meyer's 3-act process.  That...or they looked at the formula sheet or remembered the answer from their elementary school days.

Let's see how they did:

 I guess they couldn't be bothered to peel that other portion there to get its true surface area?  I guess I should have done more teaching and less snapping of pictures here, as I could have demonstrated that by peeling the skin into smaller pieces would more accurately depict the surface area.  Right now, much of the 'surface' area is used for the third dimension of height severely downplaying the true surface area of this orange. 

 That clementine there looks quite tasty.  I must mark these students' self regulation skills to be excellent in their ability to stay on task without eating some juicy fruit.

 Now that clementine looks quite symmetrical...and tasty.

Ahh, "four" circles!  The 'true' answer.

Now this group featured a student who made the best notes ever and another student drew some of the best art on evaluations.  The illustrations left behind were both profound and thoughtful.  It's no small wonder that they took the time to rip the orange peels into symmetrical sizes to create the above work of art.

Anyways, this activity proved to be quite memorable.  It's a good one and one that I'll continue to do every time I teach grade 9 as it somewhat demonstrates how the surface area of a sphere is 4πr^2 or the equivalent of the area of four circles.   

Capitalizing on the Hour of Code: An Alternative Assessment for Solving Equations

So last week was the Hour of Code.  Our wondrous computer science teachers have decided to involve all the grade 9s and organized a tremendous time in the cafeteria involving 500 students.  I had quite the fun myself as I tackled some good old HTML coding as well as some Star Wars programming.    

I heard from a few of my 9 academic students that they've done this before, but they got a lot more out of this session than in previous years.  They don't realize that maybe perhaps last year's experience set up today's success.  

I wanted to integrate programming into the course.  So I assigned some homework:  

For homework the night before, I had given each student a different set of four numbers.  With each of their four numbers, they were required to create their own 1 step, 2 step, and 2 step equations involving distributive property.

I then introduced my scratch assignment to my 9 applied math class using the previous week's Hour of Code as a springboard.  Students are to make a multiple choice quiz on Scratch with the four questions they did as homework the night before.  I had them start off with a template.  

Some had a little hard time with this because 1) I didn't give them that much time to play with it (one official period only...and 2 other mini periods where they had a choice to study or do this assignment)  and 2) it was introduced in the last week of before holidays when a few other assignments from other classes were due and 3) their reception for learning something completely new wasn't quite in this last week.  

About a third of my class got it done perfectly.  Take a look at this example.    

Others don't know to check and debug.  I know she can solve equations and build equations as I've assessed her separately on a previous test means that she hasn't debugged program properly:  

  

Here's one student who went above and beyond by using the 30 minutes of introduction and probably previous programming experience to add some bells and whistles to the template I introduced to them:  
There are some that have yet to hand it in.  

I'm going to have to do some work after the break;  I'll probably introduce some peer assessment process to help them go through the debugging process and then help the other 30% that didn't hand it in a little push.   Should I add it to the rubric?  Next semester.

I gave them a template, and they had to follow the instructions.  It was mostly an exercise in creating their own equation, and then a matter of some data entry.  However, the program's template isn't that intuitive, so inevitably, they have to learn the process of debugging and trying again.  They experienced the confusion and pain associated with "programming" - and if they persisted, the joy of "programming" in a microcosm of one period.  

I guess I can give myself a point for integrate programming into the math curriculum without having it take up more time than necessary.  At the same time, it can be argued that they learned more about data entry than programming.  I'll live with that - I've rarely been able to cover the curriculum well in an applied environment and to be able to do something new like this is quite a luxury - especially with the EQAO test next month.  

Alternative assessment of the year?  Done.  Will I try it next semester?  Let's see what my colleague says.

Anyways, here's the rubric (also attached) that I used:

A Student Teacher, Teaching the Teacher

A Lesson on Felicia

I have ALMOST given the full reins to my student teacher lately every Thursday when she comes to volunteer. 

I use the word ‘almost’ because a student teacher never truly has their classroom management tested as they’re walking into a classroom with established norms and systems in place that hopefully protect supply/student teachers. 

I’m also in the room while she teaches, which affects the management of the classroom.  

On a separate note, for the first time in eight years, I can say that my applied classroom norms extend strongly even when I have a supply teacher (given the comments they leave behind).  That’s how receptive my students are this year. 

That just means that next year, my students will be wild and out of control, doesn’t it?

On the other hand, my student teacher is incredibly talented and is in her final year of teachers’ college.  I have learnt much from her style, approach and her creativity; case in point, take a look at her lesson on Felicia that she made up:

The question, I could see, resonated with the girls in my classroom.  I guess after questions involving video games, Usain bolt, etc. this was something new. 

My student teacher and I coordinated through my spiral curriculum well as the question was just a touch out of their comfort zone as they just finished learning solving equations and we’ve been through perimeter and area about two times before in previous spirals. 

The question was challenging as they got into groups of two or their ‘rate of change’ partners.  This question demanded the large whiteboards.   

For some reason, the students have been naturally lately looking to group their pairs into group of 4s and 6s.  I immediately broke up the group of 6 as I know that group was just too large.  I let the group of 4 stay as I knew that particular group of 4 worked well.  I still, prefer pairs, so I'll probably split them up next time.  

However, I wanted to see how well they worked and learnt; the next day, I went over it briefly and summarized positives and negatives of each group in terms of their process work, communication, without stating the answer. 

To truly assess how well they worked, I put up the question again.  Now, usually I am not a fan of re-doing a question, or re-assessing the same question, giving multiple opportunities, and doing it in groups…but I’ve been reading so many positive reviews of it that I decided to truly try it again.

It actually worked.

For thinking style type questions, putting the students in groups and allowing multiple opportunities created an environment of learning.  The majority of students actually tried it on their own (except the bottom 5% of the class where collaboration occurred immediately..) before starting to compare answers.  Upon finding differences, these students went through learning conversations where they justified each other’s work. 

For a question that we did yesterday and that I took up earlier, it took almost 20 minutes to get it done.  Some students didn’t even finish.  I guarantee you, as I walked around the classroom listening to their conversations, none of them were fooling around. 

Mind you, I still hesitate at the thought of doing summative thinking questions in groups with my academic students because I know the ‘Mr. Shin caught your mistake’ current environment I’ve set up would cause more of my students to copy off other students as opposed to learning it. 

I am really going to have to rethink my teaching as I found that those rich discussions that the students had with each other is worth designing the curriculum for.    

What’s hilarious is that the education world made this discovery about math education about 5 years ago when Dan Meyer first landed in a TedX talk.  Education has already moved on from this to the next phase – but at this point, the latest stuff is too progressive and far left reaching for me. I've never been an innovator; I've always been a late adopter myself to make sure the 'latest' trend actually sticks around and works with the common teacher.

Maybe if I was an elementary school teacher, I would make the jump ASAP to the latest educational trend; but as a secondary school teacher where post secondary institutions require a certain level of standardized skill, I don’t think I could ever make that jump.  

Maybe in another 5 years I’ll make the switch if it has proven to be more than the latest trend.

Things just move so fast. 

Anyways, I’d like to take this opportunity to thank my student teacher for using her beautiful question as a springboard into student learning as well as mine.  

Causality vs Causation and an Intro to Graphing

The second spiral was a short introduction to relations.  I started off with the concept of a rate, and created my own version of the "pumping gas" problem from Mr. Orr's "tap into teen minds". 

One of the best things that Mr. Dan Meyer stated about this was how the video can be used as a 'hook'.  Boy, did I underestimate the power of this hook.  Combine this hook with open ended questions, and Dan Meyer was absolutely correct - all sorts of learners participated, even the weaker math students.

The video even out the playing field and it was magical to have such engagement in an applied classroom.  In all of my eight years of teaching (I know, I'm young), I have never, ever seen this.

Another thing that has me pleasantly surprised - were the questions being asked.

"What car is it?"
"How many litres can your car hold?"
"How many litres did you put in?"
"How big is your car?"


"How much did you pay?"


It is so intriguing as some of these questions did not come to my mind, yet each of them are indeed connected to math.  In many ways, my converging mindset could only think of the one question I really wanted (ie:  what is the price of gas per litre?)  I must work on my divergent thinking.

After a day of rates, we went on to the topic of scatterplots.  Now understanding the importance of a hook, I started the students off with a 30 second paragraph of Tyler Vigen's graphs of spurious correlations

The causality vs correlation issue is often a huge source of consternation for those who frequent the forums online, and I just wanted to introduce this common pitfall. 

Hence, my Friday assessment of scatterplots and rates was chicken and crude oil related, much to the delight of some of my students.  Or chagrin.  I'm still learning to read some of them one month through.

On a side note, a few of my students were trying to force a connection in this above relationship depicted by the line graph to make sense and ventured a hypothesis thinking that the chicken was being cooked in the crude oil. 

My mind is still blown that I have such a high engagement level. 

I'm proud of the students.  Let's see how long we can keep this up.

Look ahead:  I'm spiraling back to the Pythagorean theorem by starting off week 4 with  perimeter of composite shapes.  Now that we've completed an initial assessment and a reassessment of week 1, I know exactly who to target tomorrow for individual help.  This is an incredible advantage of the spiral curriculum. 

Assessment of the First Spiral

Even though I've been teaching for eight years now, I turned everything absolutely upside down.  I'm now working with a spiral curriculum, performing Dan Meyer's 3-act math on a regular basis and implementing some serious classroom management techniques that was recommended to me from my last year's mentee.

My first spiral which consisted of Pythagorean theorem, perimeter, collecting like terms, polynomials, area and distributive property was a success by my books thus far.  They did well on certain portions of their assessment, but other not so well.  I crunched a lot of material in 1.5 weeks, and they struggled with the last portion - distributive property.  Or rather, I didn't give enough time to allow for the students to work with it.

Nonetheless - I borrowed some growing success initiatives from my science department, my wife, and another math colleague.

1)  An adaptation of my science department's concurrent credit recovery policy,:  if the students failed the assessment overall, they could get a second hack at the assessment.  They must perform at a level 3 (~70%) for me to bring their marks (all of K, A, T, C) up to 50%.

2)  Wife:  Since I was devoting class time for students to have a second hack at the assessment, I allowed the other students to try to upgrade one question.  My one page double sided assessment had a couple of thinking questions - one from homework which I took up and another one that was a little extension.  As a result, all of my students had 'something' to work on.

3)  After going through the whole assessment, students can choose to look in their binder to help them with any question that they may have trouble with.  I've been trying to give students incentive to keep an organized binder, and especially with this spiral curriculum, we have topics everywhere.  Well, armed with their organized binders, students can now use their binder (at the cost of 50% of the mark for the particular question), students can now and try to get the remaining 50% of the question.

Intro to Pythagorean Theorem

Today, I have officially decided to follow and jump on the Dan Meyer bandwagon by introducing a problem using his 3-acts.  However, I have more specifically jumped on Mr. Orr's bandwagon, as he seems to be the Canadian version of Dan Meyer from what I've read on his blog.

To start myself off on this 3-act business, I have copied Mr. Orr's video on "Corner 2 corner" with this video below:

I requested that the students write down any questions that come to mind - even non-mathematical ones.  I had some trouble amalgamating their questions as well as leading them to the question that did matter - but I have tremendous students that eventually got to the question I wanted:  what's the length of the room from the top corner to bottom corner? 

My favourite part of the whole exercise is the estimation portion.  As per Dan Meyer, it's best to ask students to answer the following:

•  What's a number that's too low? 
•  What's a number that's too high?  
•  What's the exact measurement?

Take a look:

We then discussed a plan of how to find the length of the string.  With some guidance, a couple got the concept.  Reinforcement is definitely necessary tomorrow.  

Instead of giving all the measurements, I felt that my 9s needed some movement - so I split them up into groups and they went about counting the tiles on the ground to calculate the width and length of the class.

We finished it off with some calculations and got the answer.  We have two people who guessed very close to the answer!

I'd say my first 3-act execution was somewhat of a success.  Let's hope I improve on the next one!

Activating Prior Knowledge

Well - here I go, trying to spiral my way through 9 applied math.  First day started with some serious structure laid down in hopes of preventing those inevitable fires that come about in the oncoming months.

As one of my favourite colleagues from MDHS often described teaching - it's "trench warfare out here." I certainly laid a dug a deep trench and it started well.  My students and I battled the math together on the first day.

We started with some prior knowledge activation as was suggested by my fellow colleague Ms. Phan out in Ottawa-Carleton District School Board suggested that I do.

Here are some of the results of today's prior knowledge activation in which they tried to brainstorm as many topics as possible and categorize them under different levels of confidence.  

2015 - Here we go!

Another year, another post.  This year's a little different than most with all of your applications to university due and you're wrapping up your 7/8 of your high school career.  Exams are coming up as well as a multitude of final assignments and projects.  You're probably experiencing stress as you have never felt before. I respond to you with this:

Colleges in the US and universities in Canada are turning to puppy therapy to help relax their students.  Puppies can be found in libraries and study halls throughout the university as a proven stress reliever. 

Here's an article on McGill University with their puppy room. 

Now that you're a little more relaxed, you're ready to catch up with the latest in science news! 

This professor can't get funding for his warp drive research because it's "too far out there".  It doesn't  stop David Pares though as he's willing to continue his research in his garage after a full day's work of teaching.  He's convinced of all that anecdotal evidence of veteran pilots who have traveled through serious electrical storms around the world and in the Bermuda triangle and find themselves 100 miles away from where they should be.  It's happened too often to far too many pilots in the past half decade that this man believes there's a correlation between high electrical activity and the ability to bend space.  Some physicists actually believe he's on to something.  Read more here.  

Some person wondered what would each of the planets look like if they were as close as the Moon.  Here's an animated GIF that I cannot corroborate on its authenticity but it's fun to look at nonetheless.

 A 5,500 year old fossil of an aboriginal woman found in Canada has its DNA analyzed.  It was found in BC's northern coast where many members of the indigenous First Nations currently live and apparently have lived for many years according to their history.  Their claim of living there has been verified by matching the DNA of that fossil with a living person who is now scientifically the 200x great-grandaughter.  That's a lot of generations.  Take a look! 

Remember those infographics and concept maps I assigned?  They're an increasingly important method of visually communicating information and its shown in WIRED's top 2014 science visualizations of the year.  Above what we see is a computer animation of a coronal mass ejection from the sun with the Earth in the background.  Make sure to look at the rest and make sure to read the captions. 

A mathematician has found a better way to get to Mars on less fuel.  Instead of aiming at the intended target and using extreme brakes (fuel) to arrive safely, the mathematician has shown a method of slowing down earlier at a proper speed enough to be gently pulled into orbit by the gravitational pull of the target.   It will be slower, but it's much cheaper. 

Again, I've shown versions of this before, but here's a video version that came out xmas eve with extreme font to annoyingly hammer it home that we live in a very, very, small portion of the universe.  Have fun in your last few days of holidays - I know I will, because I'm marking. 

 

Impressive Infographic

A reddit user has posted a spectacular infographic visually explaining how every planet in the solar system would be able to fit between Earth and our own moon.  I didn't believe it myself, and was about to go and dig up all diameters of each planet - but, it's already done.  Also, Wolfram-Alpha, the google for calculations, can give the total diameter in one query.  

Math is Used to Explain the Universe...

 Math is always been abstract.  Then, at some point, science catches up and can often utilize that math to describe and predict the happenings of the universe.  For example, the imaginary numbers you learned about in Gr 11 math - I used it to partially describe electricity's behaviour while studying in university.

XKCD, a popular comic, compares math and science based on purity:

Math is a convenient tool to describe the things we can't really understand - like black holes.  In the latest news, the physicist, Mersini-Houghton, has just mathematically proven that black holes do not exist.  She has married two known sides of science - quantum physics with general relativity with her finding, which is a pretty big deal. We'll see if it stands up to the scrutiny of the other scientists.
