Straws rafts

In inquiry we are learning about the design  process. The Design process is were you plan  design and test a product or theory. process when you test it,is does,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 straws raft to float with  40g of weight an it .we could only use straws and tape our raft failed 1 time because we did not measured it. we did some research about how rafts float and founds that hard and eyes challenging because it was so hard.
