Head outside and explore the environment you live in. Borrow the Explore Science bag and go on a nature walk. There's a hand-lens so you can get a close look at tree bark and buds, flowers, caterpillars, moss, lichens.....
For the pre-school crowd there are a bunch of nature-related backpacks with books and games and an activity book. Check out Oceans, Bugs & Birds, Stars, or the Dinosaurs.
Part of the Earth Day sensibility is to reduce our consumption of natural resources - to buy less, drive less, and reuse more. Our library is a great place for that: you can check out books and movies, play a game, use the computer - even borrow a digital camera.
If you're looking for family activities, head over to Archimedes Notebook every day this week for Earth Week activities.
