Light and Dark [PDF ebook] 

This book looks at the differences between light and dark. — Darkness is the absence of light. You can make a dark box to show how we need light to see. — Experiment using ice cubes in boxes to show that dark colours absorb more sunlight than light colours. — Look at how some animals have evolved to "see" in the dark using other senses and try it out yourself! And much more!
