Shadow Experiment

Do shadows change outside during the day?  Why do they change?  Why is the sun in different positions in the sky at different times of the day?  We asked these questions and then did an experiment to find out the answers.  We measured the length of the shadow of a 100cm (1 meter) stick at about 8:45 a.m. and then again at about 12:30 p.m.  We also noticed where the sun was in the sky at both times. We found out that most of the shadows were over 200 cm in the morning and less than 80 cm in the early afternoon.  We discussed why we found these differences and how this experiment helps prove that the earth is moving.  These are big concepts that take a while to sink in!  Hopefully, these experiences help us notice the natural world around us.
