Imagine a world without light. What would it be like? Dark, cold, and lifeless! In Explore Light and Optics! With 25 Great Projects, readers ages 7 through 10 find out why light is so important to our world. We use light to communicate. Because of light, there are natural phenomena such as rainbows and the auroras. And it’s light that provides living things with the energy they need to exist. In Explore Light and Optics!, readers learn how light travels, how the eye works, and why we can see objects. They read about optical inventions that changed the world, including microscopes, telescopes, and cameras. Kids are introduced to modern inventions such as lasers, solar planes, and the hundreds of thousands of miles of fiber optics that make it possible to transmit data all over the world. Through projects ranging from making a spectroscope and concocting invisible ink to creating a periscope and experimenting with lenses, children discover how light can be bent, bounced, and broken. Fun facts, jokes, cartoon illustrations and links to online primary sources spark an interest in the fascinating role light plays in our lives from the sun shining overhead to the cellphone in our back pocket.
Young scientists will learn the power of physics when they make their own lemon batteries, demonstrate centrifugal force, and exhibit how sound energy travels. They will identify magnetic poles, learn what the best conductor for heat is, and even determine why eggs don't break beneath their bird guardians. Color illustrations and safe, simple step-by-step instructions will guide readers through this collection of twenty-four physics experiments from celebrated educator Janice VanCleave, empowering them to learn in a tactile and entertaining way.
The stepsisters yell. The fairy godmother sings. The pineapple-turned-monster-truck burns rubber on its way to the ball. For Cinderella, this evening is an enchanted STEM adventure through the science of sound. For readers, it's a treat of a fractured fairy tale, complete with an ear diagram, a key-term glossary, critical thinking questions, and a sweet pair of glass high-top sneakers.
In a series of fun and involving hands-on physics experiments, kids charge an object with static electricity, demonstrate how static charges produce sound, use magnetic force to suspend a paper airplane, determine that objects in water have a different weight than they do in air, and learn how a substance’s buoyancy can be changed. They will also determine if shape determines the strength of an object, learn the effect that an object’s center of gravity has on motion, demonstrate how the length of a pendulum affects the time of each swing, and discover how the center of gravity is also the balancing point of an object. Featuring color illustrations and safe, simple step-by-step instructions, Janice VanCleave again shows just how much fun science can be.
In a series of fun and involving hands-on physics experiments, kids learn how to create and operate first-, second-, and third-class levers, demonstrate apparent weightlessness, and determine an object's precise center of gravity and balancing point. They will also demonstrate how a rocket moves, how the length of a flute affects pitch, and how to create sound through vibration. Featuring color illustrations and safe, simple step-by-step instructions, Janice VanCleave shows just how much fun science can be.
Who first discovered static and why was this important? What is an LED? Using natural-voice audio and highlighting text, this fascinating book looks at the historical controversies that surround the discovery and theories of electricity and tells the stories of the scientists who worked on them.Ê It also examines how the different theories based on electricity were arrived at, how they were tested, and what impact these theories and discoveries have had on our understanding of science today.
Have you ever wanted to strum music with a guitar? This book shows you how to make your own box guitar! Using simple materials and easy step-by-step instructions, young readers can explore the science of sound behind this fun project.
