Review the key concepts, equations, and skills for Newton's first law of motion, including the difference between mass and weight.

This interactive game has students apply skills in estimation, measurement, and basic addition using pearls. Students are asked to estimate the number of pearls in a treasure chest by making predictions and using number sense. The skills...

On this site, find a variety of materials to help students understand the conservation of matter. Create lessons that allow students to measure and graph quantities that could show even if matter is heated, cooled or combined with other...

Covers the meanings of force, friction, and gravity, and the differences between magnetic and elastic spring force, and between weight and mass. The effect of air resistance on an object's motion is also touched upon.

In this interactive lesson, learn what the "physical properties" of matter are and how can they be measured and observed.

Assess your understanding of the properties of momentum and impulse with this interactive multiple choice quiz. Immediate feedback is provided.

In this science lesson students will be asked the question, "Does air take up space?" and "Does air have weight?" Students will conduct experiments that prove that air has mass, takes up space, and exerts pressure.

Newton's three laws are deceptively simple, but they are the underpinning of all of physics and govern the mechanics all of your actions in everyday life. Take an in-depth look at these laws in this learning module.

Manipulate the mass of a weight and the length of string in this interactive pendulum simulation. Change the speed, friction, and gravity to make the pendulum swing change as measurements are displayed on the screen. Younger students can...

The Center for Mathematics and Science Education at the University of North Carolina at Chapel Hill provides an interesting and easy-to-use dictionary of the history and meaning of many measurement terms. Metric, International, and...
