In grade 10 we are working on proving concepts using analytic geometry.  We are also working on how to make a plan and solve problems.

We worked hard before the break to solve problems out loud, and take note of how our peers tackled problems, and setbacks.  This has helped us get more practice and confidence.

We are now better able to tackle problem solving independently.

It’s spring today so we are planting beans!

We designed experiments in groups and decided what variables we will change and what we will measure.  We need to keep a lot of variables constant during our experiments.  We will keep track of our observations and see how our beans sprout over the week.

We looked at he relationship between diameter and circumference todah

We made a graph showing all of our class data

We noticed it is linear, positive and shows a strong correlation.  We can use a line of best fot and interpolation and extrapolation to solve problems.

We also noticed that the rate of change is 3.14 (perfect for pi day)

We sang a pi day song (to the tune of oh christmas tree) and talked about irrational numbers.

And finally ate some pies!

We are looking at algebra in grade 9, and are using algebra tiles to help us visualize some abstract concepts.  We can add and subtract polynomials now, and model perimeter and area.

We popped corn today.  We started off by brainstorming all the things we wondered about, and all the questions we could make and solve regarding popcorn.

We measured volumes, and volume changes, we timed how long it took to pop

We made containers out of one cheed of paper and tried to maximize the volume.

We noticed that the buckets aren’t perfect cylinders, so We figured out how to approximate the volume, and then checked it using our known cylinders.

We did a lot of math and explored so many different things!  It is hard to imagine how many explorations came from a bag of popcorn.

 

How far will a ruler fall before you catch it?

We tested our reactions today as an introduction to Kinematics, our next physics unit.

We’re paper free today!

Today in physics we learned about how hearing works, and how hearing can be damaged, and what technology is available to help when there is hearing loss.

We had a guest speaker come in to talk to us about her cochlear implant, and how her hearing was damaged.

In physics we used a tuning fork, pvc pipe, water and a ruler to determine the speed of sound in the room, and from there we determined the temperature.

We used the tube in water which acts as a closed end resonating air column.  We can extend the tube to find the first resonant length of the tube.  It really sounds loud at a specific length due to how the 256 Hz tuning fork excited the air column.

Today we are having a follow-up workshop led by Link Crew leaders.  We are discussing strategies to get through challenges.

We made paper airplanes with a partner, but both using non dominant hands, and not talking.

That was a challenge!  We all could do it, but it took a lot longer than we expected.

We then had to throw them into a basket, using our partner and non-dominant hand.

That was a challenge!

We discussed limitations that we have in school, and how to persevere and work through the challenges that we have.  Some strategies we talked about are using an agenda to stay organized, working in groups to talk about what you are learning, practice the things you are not so good at yet.
