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!
