On Friday 9th Feb, P7 investigated a variety of weights. They began by getting a feel for heavier weights like 1kg and 1/2kg and then very light weights like: 1g, 5g, 10g and 20g. After that, while working in pairs, the pupils had to use their prior knowledge to estimate the weights of everyday items in the classroom, then weigh the items and see how close their estimates were. As the class developed, the estimates became better and better so all in all, it proved a very worthwhile lesson!
