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.
DIY Drawing and tracing using shadows: great craft/art for kids too. "Nature and shadow- what if we take out the paints and paint in the lines…."… great idea for tracing. Take a quick pic then don't have to worry about sun changing places.
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.
