Light-Shadow tracing ~ so simple, yet so brilliant. It was this picture that inspired me to get the old light projectors from the school storage, and do a tracing activity for Groundhog Day. The kids loved the light and shadow experiment.
Trees study- From: I'm a teacher, get me OUTSIDE here! Sorting sticks from longest to shortest. Good outdoor group activity for preschoolers that can be left for individual students to return to time and again.
