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 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 float with 40g of weight on it. We could only use 20 straws and a meter of masking tape. Our raft failed 2 times because it turns out for a straw raft to float you need to make the raft less then the water. We did some research about how rafts float and found that the straws have to be perfectly in line and not all wonky. we found it hard because we needed more straws.
