In Science, we have been studying ‘Forces’. We have enjoyed working in groups to plan a fair test to investigate the effect of applying force to a spring. By talking together, we had to decide how and where to hang a spring to which we would add weights (force), adding more weight (force) each time. To make sure that the test was fair, we decided to change only one thing – the weight added to the spring each time. Everything else had to stay the same - where the spring was hung, how the weights were attached to the spring etc. Today we worked in our groups to carry out the experiment we had planned. One group attached the spring to the branch of a tree.Another group attached the spring to a window fixture. Two groups attached the springs to door handles. And one group even hung the spring from part of the playground equipment! Each group recorded their results, measuring carefully how far the spring stretched each time a weight (and force) was added to it. Back in class, we discussed what we found out, drawing conclusions about our results.
