There's a new kid at Camp Dakota! It's Megan's first year, and all she can think about is riding horses. But gravity seems to be getting in the way of all the campers' fun, from the stables to the beach. Then the big cuckoo clock in the main cabin goes missing. Who would take a cuckoo clock? Can the campers use the weighty facts they've learned to solve the mystery of where it went—and why? Look in the back of the book for experiments and more to...

Simple language and humorous illustrations show how forces make things move, prevent them from starting to move, and stop them from moving.

"In this interactive picture book, young readers poke, roll, and slide objects on the page, using their imagination to conduct simple physics experiments. They learn about forces (pushes and pulls), inertia, gravity, acceleration, and friction. Back matter includes a real-world experiment"--

"Two kids explore the ups and downs of gravity in this introduction to physical science"-- What happens to a ball when it rolls off a table? Why doesn't the ball keep rolling straight up or fly up off the table? The answer is gravity. Adler explains how this invisible force operates in the real world. -- adapted from jacket

You have probably seen movies or television shows about space travel. When space travelers go outside their ships, they use jet packs to tie themselves to their ships. They do this because outside their spaceships there is no force that keeps them attached to the craft. Without something to keep them attached, they would just drift off into space because there is no gravity. Gravity is also the reason why our bodies don't just fly upward into...

Forces move everything around us. That may sound scary and complicated, but this book shows readers that forces like friction and other laws of motion can be fascinating and fun! Innovative flowcharts bring these abstract concepts to life via brilliant photographs matched with fact boxes showing readers how the moon impacts tides on Earth, and how magnetic forces act on matter throughout the universe. From the tectonic plates that move Earths crust...

Learn why projectiles follow the paths they do and what factors influence those paths. Readers who are fascinated with potato cannons, slingshots, and rocketry will love taking that next step and applying what they learn about the laws of physics to the science of figuring out where to aim. The science of ballistics is a fascinating topic for anyone who's ever thrown a dart at a dartboard or watched the thrilling last-minute shot of a tied basketball...

Introduces physics concepts to young readers and offers instructions for related science projects.
