Year 3 took advantage of the sunshine last week and carried out a scientific investigation. At 3 points during the day we drew around a child's shadow. We used the same child each time to ensure that our investigation was a fair test. As you can see in the photo, the shadow was in a different place at each time. The children were able to explain that the shadow had changed because the sun (the light source) was in different  position in the sky. We then could discuss how the earth rotates on its axis every 24 hours.
