Most of us take light and sound for granted, but imagine a world without them. How fast does light travel? How does your ear work? Discover the answers to these and much more in Light & Sound. Packed with fun scientific ideas for children to put to the test easily and safely, using readily available materials, Light & Sound will get young scientific minds thinking, bringing the everyday application of science right to their doorstep. Light & Sound is one of four titles in the Mad About Science series. This is a bright, colourful series designed to help Key Stage 2 children (7 to 11) develop their scientific skills and knowledge, mainly by learning at home in support of their National Curriculum classroom studies. Each book is packed full of easy-to-perform experiments illustrating basic scientific theories and processes. No special equipment is needed for the experiments; everything required can easily be found in the average home. As well as the experiments, there are lots of Amazing Facts and Did You Know? boxes to intrigue and amaze. The books are fun and stimulating and make science truly accessible and enjoyable.
