Tonight we were investigating different ingredients for making glue (child friendly). The pupils had 3 different sets of ingredients to make their different glues from. When they had made them, they tested them for strength, washability and waterproof properties. The pupils used their glue samples to stick two pieces of cardboard together to test for strength. Next they used each sample to stick two lolly sticks together. When the glue has dried, the sticks will be put in a bowl of warm water to test f the sticks stay together which would suggest the glue is waterproof. The final experiment was to coat small pieces of fabric with each glue sample. When these are dry, the pupils will use warm soapy water to see if the glue comes off. We will complete our results and conclusions next week.
As you can see from the photos, it really was a sticky problem!
