Best Selling Books by Steve Tomecek

Introduces matter, including states of matter, how matter is measured, and how atoms are arranged.

A whimsically illustrated survey of the earth's rocks and minerals explores some of the many ways they have been transformed into usable materials from talcum powder to silver jewelry, in a reference complemented by a bonus activity suggestion.

Offers teachers twenty-five science activities directed to students in grades four through eight.

This book examines the issues of global warming and climate change.

Learn about the uses of man-made materials in everyday life.

Food explores some of the scientific principles involved in the production, preparation, and preservation of food. Discover why food is a form of stored solar energy and how everything you eat can really be traced back to the sun. Learn how cooking food involves some rather complex chemical reactions and how even something as simple as making ice cream depends on the laws of physics. Hands-on activities help bring the science of food to life, with topics ranging from why food tastes the way it does to how acids and bases produce chemical changes in food as you make cheese and marinate meat.

A collection of experiments about static cling and magnetism, using such items as a balloon, newspaper, and steel nail.

This hot new novelty package features a real Flip 'N Fly boomerang made of ultra-light, non-toxic foam so it's perfect for outdoor or inside play. Easy-to-follow directions plus a dozen games and activities and simple instructions for making more boomerangs are included.

Science plays a big role in how we create and use the tools and machines that help us in our daily lives. Scientific principles can be found at work in everything from the simplest hammer to the complex robotic devices found in modern factories. Tools and Machines describes when humans first started using tools and traces the evolution of tools from simple stone implements to the high-tech devices of today. Filled with full-color photographs and illustrations, this new volume also features simple experiments that clearly illustrate these science concepts for readers.

Introduces stars and what they are made of, how they shine, their positions with relation to earth, and more.

Offers information about sapphires, rubies, fossils, granite, quartz, and sandstone. This book gives an introduction to geology, where kids will learn how rocks form, what kinds of rocks there are in the world, how to find different kinds of rocks, and how to identify them.

Is it true that heat waves can make roads break apart? Yes! When it's extra hot, the materials that roads are made of will swell and start to crack. Really high temperatures can even melt the pavement.

This guide was developed to extend the concepts and experiments presented in the video series.

Examines some of the scientific principles involved in sculpture, painting, photography, and architecture, and provides scientific activities and experiments that demonstrate those principles.

Work is a critical part of life on Earth. People are constantly at work building structures, hauling freight, creating new products in factories, growing food on farms, and more. To accomplish all of this work, we've invented machines that need power to make them run and energy systems operated by wind, water, steam, electricity, and fuel to create this power. Work, Power, and Machines investigates the scientific principles behind work and traces the development of machines from ancient hand tools to the more complex devices used today.

Suggests experiments with reflection, refraction, lenses, and color
