The design process where you plan, design and test a product or theory. Something 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 Our raft failed a lot of times because i think we put to much weight on it We did some research about how rafts float and found that we just put less weight on our rafts. It was challenging because when we build it it keep falling apart.
