Here's a force to be reckoned with in the physics classroom! Scholars discover the movements associated with tension, compression, and other common forces through a hands-on simulation. Pupils pull, push, and twist their way through each...

Why is wood good for building houses, but not the best choice for high-rise apartments? Future materials scientists put building materials to the test using a hands-on interactive. Pupils pull and push on substances such as reinforced...

Everything from pens to cars use springs — some are just on a larger scale! An interactive simulation encourages pupils to stretch and compress springs while observing the changes to force, displacement, and potential energy. Then they...

A poem is compressed speech, like a can of frozen juice with all the water pressed out. An interactive teaches users how to reconstitute the language, the structure, and the literary devices to appreciate all the subtleties the poet...

Plunge into a gas pressure activity! Junior physical scientists manipulate a syringe to study the particle model of gases. The interactive invites investigations of particle movements in capped versus uncapped syringes.

We can't see most gases and we can't see things at the molecular level — but that's about to change! A simulation shows pupils the activity of molecules in a gas. The simulation allows scholars to vary the volume, heat, and...

Twenty-four questions about matter, the states of matter and the properties of matter make up this interactive online worksheet. Your class will determine the volume of water, the shape of water and the shapes of matter.

Understand what it takes to control planes safely. The first lesson in a series of six introduces the class to the air traffic control situation. The pupils develop their understanding of units used in air travel, then learn how to read...

In this conductors and insulators worksheet, students answer 11 questions about electrical resistance, conductance, gauge scale, and breakdown voltage.

In this conductors activity, students complete 15 problems about conductance, strain gauge, and electrical resistance of conductors.

In this static electricity activity, students complete nine questions about electron charges, coulombs, potential energy, voltage and the Van de Graaf generator.

In this online interactive submarines worksheet, students respond to 11 fill in the blank and multiple choice questions regarding the information included in the provided paragraph.

[Free Registration/Login Required] Observe what happens to volume as pressure is changed, and then answer a challenge question after the activity.

Change variables in this simulation to see how compression affects different states of matter.

An interactive simulation will heat, cool and compress atoms and molecules. Watch as they change between solid, liquid and gas phases. Recognize that different substances have different properties which will affect the temperatures for...

Stretch and compress springs to explore the relationships between force, spring constant, displacement, and potential energy. Investigate what happens when two springs are connected in series and parallel.

This lab is designed to have students investigate the transformations that occur when elastic potential energy is converted to kinetic energy. Students will be able to modify the mass of the object, the spring constant of the spring and...

Physics tutorial on measuring the speed of sound in dry air. An interactive form allows the student to practice solving problems involving the temperature dependence of the speed of sound.

Great animations showing how sound is produced.
