Yo-yo's are a fun toy and there is nothing simpler than a string wrapped between two connected disks. But there's a lot of physics that makes a yo-yo work. In this science fair project, learn more about how and why a yo-yo works. You...

Hands-on challenge to design and build a paddle boat that moves across water using a rubber band as its power source. Provides full list of materials with ideas on how to design, build, test, and redesign it if necessary. Activity...

Students will learn what causes reactions and what affects the rates of reaction through data collected by conducting several simulated experiments.

Let this classic family of monsters guide you as you learn about energy. Interactive exercises, experiments, and demonstrations help to build knowledge and raise questions.

Create a simplified roller coaster with this simulation by creating a track shape for a ball to travel on. Students can change gravity and damping. Site includes equations to help students understand what is happening in the simulation.

During this project, students will be asked to design a device that will measure out a time period of exactly 3 minutes. They will be asked to brainstorm ideas using the different materials provided. Students will observe and explain the...

Students must predict the distance traveled by a person on a BMX bike. The person will start with potential energy due to gravity and then convert it into KE. They will then hit a ramp and become a projectile. You have to predict how far...

This tutorial investigates pendulum motion and how a variety of quantities change over the course of time. Such quantities will include forces, position, velocity and energy - both kinetic and potential energy. Take the interactive...

Students must predict the distance traveled by a person on a sled. The person will start with potential energy due to gravity and it will turn into KE without loss. They will then lose their energy on a level surface at the bottom of a...

A handy resource that gives an overview of equations and definitions pertinent to an introductory, college-level physics course, with two of its three sections focusing on motion-related topics and principles.

With craft and recycled materials, kids can make all kinds of rolling vehicles. Add balloons to make this balloon car and see Newton's laws of motion in action.

In this hands-on activity students learn about the laws of physics by creating a marble roller coaster.

Students are introduced to the basic principles behind engineering and the types of engineering while learning about a popular topic - the Olympics. The involvement of engineering in modern sports is amazing and pervasive. Students learn...

Use animation and other interactive strategies to help understand physics principles. Change the track and height to see if your ball can make it to the end.

Examine the link between molecular motion and energy. Observe the movement of a molecule at room temperature. Learn about the different types of molecular motion.

For this experiment, learners will design a track for a rolling ball to try to have the longest roll time possible. They will, in the process, apply their understanding of kinetic and potential energy, and acceleration and deceleration.

This site from NASA states Kepler's second law of planetary motion and depicts its meaning with an informative diagram. Relates the law to conservation of energy principles and discusses the eccentricity of a satellite's (or a planet's)...

Find out about the first and second laws of thermodynamics, and how they relate to the biology of life.
