Inquiry, Straw boats

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 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 0 times because we   
covered up all the ends.We did some research about how rafts and boats float and found out that it all depends on the weight.We found putting the straws challenging because the keeped on rolling out of the tape.
