Today, the children conducted two experiments to investigate our new topic of light.
Firstly, the children used torches, mirrors and different objects to investigate whether light travels in straight lines or if it can bend around an object. Each group came to their own conclusion and used thought bubbles with sentences openers to prove their conclusion. We discussed our findings as a class and found that light travels in straight lines.
Secondly, the children were given the hypothesis: “Shadows have the same shape as the objects that cast them.” Each group worked together to conduct their own experiment to prove or disprove this hypothesis. They had to consider how they would conduct a fair test, measure their results and ultimately write their own conclusion. They conducted their experiments and discussed their results – considering how the fact that light travels in straight lines explains the existence of shadows.
