Oh No! Mr Bean’s teddy has lost its head!! What are we going to do to sew it back on? We are going to need thread which is strong and flexible but which one? Students experimented by testing which type of thread was the strongest out of 1. cotton, 2. plastic/nylon, 3. yard/wool and 4. poly string.

They did this by testing how much weight each string could withstand before breaking. Here are some pictures of how they carried out their experiment.

LI: We are learning how to design fair experiments where only one variable is tested. We are learning about strength of strings

SC: I /we can test each type of string with weights to see which one would need the most weight before breaking or snapping
