This half term, we have continued to look at forces in Science. We are exploring how different mechanisms can be used to help reduce the effort needed to move a load.
The children have started off by exploring how the effects of water resistance on different shapes. We dropped a triangular, circular shape into water and timed how long it took to reach the bottom. This allowed us to understand the term streamlined.
We then starting looking at levers. We identify the different parts of a lever – beam, fulcrum and load. We then went on to making are own levers with the children’s equipment. The children used a ruler, a whiteboard pen, rubbers and glue sticks to construct their levers. They explored what happens when the fulcrum (whiteboard pen) moves closer to the load and were able to explain the outcome.
