Straw Rafts

In inquiry we are leaning about the Design process. The Design process is where you plan ,design and test a product or theory.Sometimes when you test it,it doesn't work and you have to start at the beginning again to see how you would make it better .Mrs McG gave us a challenge. We had to plan,design+build a straw raft to float  with 40kg it was really hard my problem is me and Carla didn't make the straw raft that good I found it hard I found it challenging.
