dirty hands bread experiment - what a great way to demonstrate the importance of proper hand washing. Would love to see what happens when you wash hands with warm soapy water versus hand sanitizer! Would make a great science fair project.
Earth Day Experiment ~ Can You Undo Water Pollution? In this experiment the kids learned just how hard it is to undo water pollution. a bucket of clean water, some household trash, vegetable oil (to stand for toxic oil spills), tongs, and a strainer.
