Testing materials

The challenge was to find the right material for a pizza delivery man's jacket.  We first looked at the properties that the jacket would need.  We decided it would have to be waterproof, strong and flexible.  We then thought about how to test the four materials that we had to choose from. We scrunched all of the materials and found that all were flexible.  We then took the materials to the water tray where we poured water over them to see if our covered hands would stay dry.  Only two materials passed the waterproof test so we moved to the rip test, where we tested how strong the two waterproof materials were.  Look at our pictures to see which material was the winner.

Great science work year 1, you did a fantastic job at finding the best material for the job.
