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 there beginning again to see how you should 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 20 straws and some masking tape. Our raft failed 5 times because the straws weren´t close enough. We did some research about how rafts float and found about Dense, Buoyant, and that the straws need to be close otherwise the water will come through onto the raft. We found the design to hold the boat up with the weights on challenging because we could n´t manage to do them until some time. and we found it easy to put it in the water. Here are our pictures:
