Stretching Our Learning


2RF having been investigating how objects can change shape when they are pushed, pulled, bent or twisted. This week we’ve been testing elastic bands to see which stretch the most. To make it a fair test we always hung the same weight from the elastic band before carefully measuring how much longer the elastic band is. We also watched some videos showing how scientists do similar tests on fabrics and metal bars to make sure they can do the job they are going to be used for.
