Architects and Engineers at Work!

One of the activities the Grade 3s did to wind up our unit on structures was to take the 10 paper challenge.  They were given 10 pieces of paper and their challenge was to build a structure that was at least 10 cm. high and 25 cm. long and would hold a small milk carton with at least three dominoes in it.  Here we are in the planning and building stage!  We were reminded to use our previous knowledge about what makes a strong, stable structure.

We were amazed to see how strong our structures actually were.  Every group did something a little bit different and it was wonderful to see their learning put into action! 

Using layers and cylinders to make a structure stronger!

We know that triangles make structures stronger.  Can you see the triangles in this structure?

A foundation, four strong cylinders (pillars) and a top to hold the milk carton and dominoes!  Have you seen this design in other structures in your environment?

 Meanwhile, the grade 2s showcased what they had learned about the 3 states of matter.  This was done ALL BY THEMSELVES!!  Aren't they a smart group of thinkers?  I was very impressed with their knowledge!
