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, 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 and build a straw raft to see if it floats with 40g of weight on it. We could only use 20 straw and tape. Our raft failed one time because it was long and the straws where far away for each other. We did some research about how rafts float and found out that you need gravity and buoyancy to make a raft float. We found building our raft the most challenging because measuring the straws and putting them in the right spots.
