students will explore making shadows and tracking the movement of an object over the course of a day to look for patterns. It is best to couple this shadow activity with reading the book, Bear Shadow, and making a map of Bear's neighborhood when the sun is relatively high in the sky, either near the beginning or the end of the school year. You'll want to measure sun shadows at least twice and perhaps three or four times during the year to see how they vary with the time of year.
