Books in Exploring Light series

The field of biology focuses on living things, from the smallest microscopic protozoa to the largest mammal. In this book you will read and explore the life of plants, insects, spiders and other arachnids, life in water, reptiles, birds, and mammals, highlighting God's amazing creation. You will learn about the following and so much more:How does biological classification give each different type of plant or animal a unique name?In what ways are seeds spread around the world?What food does the body use for long-term storage of energy?How did biologists learn how the stomach digested food?What plant gave George de Mestral the idea for Velcro?For most of history, biologists used the visible appearance of plants or animals to classify them. They grouped plants or animals with similar-looking features into families. Starting in the 1990s, biologists have extracted DNA and RNA from cells as a guide to how plants or animals should be grouped. Like visual structures, these reveal the underlying design or creation.The newest book in our Exploring series, Exploring the World of Biology is a fascinating look at life - from the smallest proteins and spores, to the complex life systems of humans and animals.

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 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 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!

Each book in this series looks at key concepts surrounding the topic of light: where light comes from, how it travels, how it reflects, how shadows are created, and how darkness is the absence of light. Packed with interesting, easy-to-understand examples, as well as a variety of hands-on experiments, Exploring Light is a fun way to discover the science of light.

Geography, a comprehensive learning resource, provides high-interest, full-color lessons to spark students’ interest and encourage critical thinking. The hands-on activities relative to state, regional, and global geography, while step-by-step map-building and comprehensive review pages give young learners the practice they need for success in this key subject area. A complete answer key to measure performance is also included, as well as a fun sticker sheet and poster.
