Exploring Light

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 colors absorb more sunlight than light colors. - Look at how some animals have evolved to "see" in the dark using other senses and try it out yourself! And much more!

This book looks at what reflections are and how we can use them. - Mirrors reflect light back at exactly the same angle. You can make a "mirror book" to explore symmetry and multiple reflections. - Why does a straight straw look bent in a glass of water? Experiment using air, oil, and water to see how different materials affect the speed of light. - Look at how our eyes use reflected light to see and make a pinhole camera to show how the eye works. And much more!

This book looks at the different places light comes from, including natural and artificial sources. - Discover the difference between a light source and a reflective object and how you can tell which is which. - Look at our largest and most important light source – the Sun – and what happens when you take sunlight away. - Explore light technology by finding out how we use lasers and fiber optics. And much more!

This book looks at how shadows are created. - Test which materials block light (are opaque), let some light through (are translucent), and let most light through (are transparent). - Look at how you can make animal shadows using your hands! - You can make a sundial to explore how shadows can change depending on the position of the Sun. And much more!
