Year 5 and 6 have been hard at work this week – we have been planning, testing and evaluating properties of materials!
First, we had to plan our scientific experiment. We decided to test the strength of bags (made from different materials) by adding weights to them, until they reached their maximum capacity. We had to think about the variables to keep and change, as well as how to remain safe during this experiment.
Well, what did we find out? It turns out bin bags are rubbish… but we knew that already. The cotton bag was a huge surprise – it could hold a huge 40 kilograms! Some pupils went one step further and showed off their data presentation skills by using bar charts and line graphs to record results.
