Straw rafts

In Inquiry we are learning 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 40g of weight on it.we could only use straws and tap. our raft failed 5 times because it wasn't straight and Tight to together.we did some research about how rafts float and found that if the gravity downward is less then the gravity forwarder I found it hard to make our raft float we found it easy to make loads of idea for a raft.
