Science Experiments
Describes projects which introduce scientific principles, and shows children how and why things work. With a flowerpot and a stick as a sundial, this book helps you follow the shifting shadows to read the time. It also shows you how to write a secret message in invisible ink made from vinegar and either lemon or onion juice.
