This week, in science, we have been furthering our knowledge on the topic of light by investigating which materials are good at reflecting light. After learning about the benefits of some materials being reflective, we set up an investigation using torches, reflective materials and card to reflect the light on, to test our earlier predictions. When our investigation was complete, we designed a school bag for use when children are walking when its dark using the two most reflective materials in the investigation: tin foil and CDs.
