Observing Forces Of Motion

Observing Forces Of Motion

When something moves, a lot is going on that we don’t see. But we can make deductions based on our observations of different movements! Try moving different objects on different surfaces and see what you learn.

Build the Eiffel Tower

Build the Eiffel Tower

From The Science and Technology of Marie Curie

Built in 1889 for the World Exposition, the Eiffel Tower honored the French Revolution. It also showcased national engineering and design expertise to an audience of global visitors. Originally intended as a temporary monument, it still looms large over Paris today, remaining one of the world’s most visited landmarks.

Make Your Own Zibaldone

Make Your Own Zibaldone

From The Science and Technology of Leonardo da Vinci

A zibaldone is the Italian word for “a heap of things.” This is what Leonardo’s notebook was called. He collected a heap of ideas, observations, questions, and experiments on the pages of his notebooks, putting everything he saw or thought into the same book, instead of having different notebooks for different topics. And he used every corner and both sides of every page. In the 1400s, books and paper were more plentiful than they had...

Experiment with Homemade Soap

Experiment with Homemade Soap

From The Science and Technology of Ben Franklin

Back when Ben Franklin was a kid, making soap was a smelly affair. It’s much easier—and more fun—today. Have an adult help you with the knife and the hot glycerin (soap).

Build a Craft Stick Catapult

Build a Craft Stick Catapult

From Engines!

Ancient armies used catapults in battle. But the catapult has been used as recently as World War I. In that war, soldiers used catapults to toss hand grenades at the enemy. Today, catapults are used to launch planes off the decks of huge ships called aircraft carriers. Because the runway is short on an aircraft carrier, the catapult helps get the plane into the air quickly. Try making your own!

Reviews

“Accurately aimed at its intended audience and complete with vivid and informative graphics, Projectile Science is an extremely readable yet factually accurate account of mechanics and its applications to projectiles.”

—Ramamurti Shankar, John Randolph Huffman Professor of Physics, Yale University

“Packed with interesting facts; sure to engage its audience.”

—Nino Polizzi, BSEE, engineering instructor, Samueli Academy

“An interesting way to make classical motion concepts relevant to young readers.”

—Vince Huegele, committee chairman, National Association of Rocketry Education University School

Detailed Book Description

What are the forces behind projectiles? Why do rocks and rockets soar through the air in an arch?

The game is on the line. You crouch, you shoot—will the ball go in the basket?

You might think that nailing a three-pointer is just luck, but there are many forces at work that determine if you’ve made a game-winning shot. In Projectile Science: The Physics Behind Kicking a Field Goal and Launching a Rocket with Science Activities with Kids, readers ages 10 to 15 learn why projectiles follow the paths they do. Young learners 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. In this book, readers learn about the forces that act on the projectiles and how to calculate those forces to make educated predictions about where their homemade rockets and other projectiles will land.

Essential questions that promote critical examination of the science, primary sources, online videos, and science-minded engineering activities let readers have a blast learning about the physics of ballistics!
