Last week in Science we discussed the differences between night and day and the things people do at different times of the day; for example eating their breakfast in the morning, going to bed at night time and so on. This week we decided to explore the way in which shadows are made. First of all we watched a video of Peep discovering shadows on the Interactive Whiteboard, then in our groups we experimented with making shadows of our own between the projector and the whiteboard with the lights off. We could make shadows because when we stood in front of the projector we blocked the light and it could not shine through. We noticed that the closer we moved to the projector the bigger our shadows became and the further away we moved the smaller our shadows looked. We made bunnies, birds and talking mouth shadows with our hands. We then went outside and traced the shadow of the basketball hoop with chalk on the ground. When we checked if the shadow had moved at lunch we found that it had moved a little, this is because the Earth spins around very slowly throughout the day and shadows are longer in the morning than in the middle of the day.
