Shire 7 Week 2 Term 3 2020

Why do things float?

Shire 7 learned about density and displacement, I wonder if you remember and can explain it to a friend?

Then we designed and created a raft. We were given 10 straws, 4 rubber bands, some modelling clay, 5 meters of string and masking tape. Our design brief said we needed a flag and that the raft needed to stay afloat for at least 30 seconds holding as many 10 cent coins as possible. Here are some photos of us making our rafts.
