Only one of these at this price. This one is 5.00-S Usborne Book of Simple Science, hardcover. Pretty good condition except for some tears in the surface paper at the bottom of the spine. The purpose of this book is to introduce children ages 8-10 to basic principles of physics by taking them through simple experiments they can do with everyday objects found at home. Basic science concepts are explained simply, but no attempt has been made to explain complex concepts that would go over the children's heads.
Illustrations enhance the text for better understanding.
