Sunny day science

We took advantage of some recent sunny weather to do an outdoor science investigation. We went outside and drew around our shadow three times - morning, midday and afternoon. We traced the outline of our shadows and made predictions about what might happen. We wanted to investigate if the place our shadow fell changed throughout the day and if the size of our shadow changed. We noticed that our shadow was cast on the opposite side of the light source (the sun). We saw how as the sun moved during the day the place our shadow fell also moved. We also found that our shadow was longer in the morning and afternoon and shorter in the middle of the day. We wondered why, so used a torch in class to investigate. We observed how when the light source (the torch or sun) was overhead it made a shorter shadow than when it shone from a low angle.
