Let's Experiment

Some concepts about light and color can seem confusing to students without demonstrations for clarification. This vibrant volume provides plenty of experiments that young scientists can do themselves to learn more about light. They're accompanied in the lab by colorful cartoons Professor Albert, Greg the Robot, and Monica. Together, they'll review the scientific method while they learn about reflection, refraction, the invisible and visible spectrum, and much more. All experiments require items that readers likely have in their homes and step-by-step activities make each process achievable, entertaining, and educational.

It's not enough to just read about scientific concepts. Science and experimentation go hand in hand, especially when it comes to slime and other gross things! The experiments in this book offer engaging and achievable methods of learning about essential topics. Each investigation details the common ingredients needed, the degree of difficulty, the time it takes, and even the expected amount of messiness! Fun illustrated characters, including Professor Albert and Greg the Robot, accompany readers in their experiments and remind them how to complete each activity safely and successfully as well as what the conclusion means.

If you want to understand the fundamentals of the forces of magnetism and electricity, experimentation-safe and guided-is key. The many exciting experiments in this inspiring volume teach young scientists about attraction, magnetic poles, batteries, conductors and insulators, and even how to make a simple electric motor. Each investigation is clearly explained through step-by-step instructions and concludes by telling readers what should have happened and why. Sidebars, fact boxes, and illustrations add to the fun experiences that are sure to aid readers in understanding essential concepts in the elementary science classroom.

Optical illusions happen when we perceive something that's not there or that appears to differ from reality. Scientists divide them into three different categories: optical, perceptual, and cognitive. Readers will be delighted to learn how all kinds of optical illusions work and how they can amaze their friends with the experiments in this entertaining volume. They'll learn how to make a sequence of drawings seem to come to life, how to make a drawing appear 3D, how to draw the "impossible" Penrose triangle, and much, much more. All activities and experiments are explained step by step through comprehensible and accessible text.
