We’ve got an experiment going in class. We are going to grow creatures.  We put them in water and they’ll grow 600%!

We measured our creatures first, and then put them in water. 

We look forward to watching them grow! 

Today was Ali’s last class with us.  We learned about civil engineering today.  We built towers with a limited number of straws, pipe cleaners, and tape.  They had to hold up marbles, in the top 20% of the tower.  There were lots of different approaches to the challenge.  We practiced good teamwork and the design process.  We tested and changed our designs several times.

 The beans are emerging, and growing fast.  

We’re measuring them each day.   

It’s fun to watch the daily changes like the leaves unfurling.  They will sure look different on Monday!

Alex, a carpenter, came to our class today to talk to us about the  math he uses when doing his job

He showed us about making a 90 degree angle using 3-4-5 triangles, and how to use a chalk line.

He shared a lot of life lessons with us that went far beyond math class.  



the beans have germinated!  Those that grew in the dark were really big.

We planted them in soil and we’ll measure them daily.

We are calculating how long it would take to empty the water from the bucket to simulate emptying an oil well.  There were two different cups, a large one that could be used once a month, and a small one that could be used four times a month.

The problem was solved using volume calculations, and rate calculations

Later we designed a better scoop that maximizes the volume and minimizes the surface area.

We’re looking at balance points today.  For rectangular objects, it’s pretty easy to find the center.

For triangles it’s harder.  We need to find the intersection of the medians.

we’re germinating beans of two varieties: red kidney beans and black eyed peas.

We’ll check on them to see when they sprout.



We ate some pie on pi day.  We also did  some experiments with circles.  This one used  licorice laces to make circles.  We compared the circumference and the diameter of the circle, ate some licorice, and repeated.  Graphing circumference compared to diameter gives a linear graph with a slope that is pi.

We read a pi story

We also, in grade 10, looked at how many cheerios fit on circles of different sizes.

When we graph number of cheerios vs circle radius we get a curved graph.
