Hands on Science Sound and Light

There are four books in the Hands-On Science series: Electricity and Magnets, Sound and Light, Forces and Motion, and Matter and Materials. Each title contains 20 tried and tested experiments. The experiments are all safe to do, use household materials, are manageable but absorbing, and offer rewarding results. Readers are told how long each experiment lasts, what materials are needed and what the results mean. Eye-catching illustrations and engaging text make this the perfect book for the budding scientist!
