A total of 29 word problems furnish practice in solving for work, energy, and force. A few of the questions display diagrams to help learners visualize the systems, and all of them list five choices from which they select the correct...

Whether or not Galileo actually dropped balls from the Leaning Tower of Pisa, this demonstration will solidly demonstrate that objects are accelerated at the same rate, regardless of mass. You will, however, need a vacuum pump and a few...

Sail to the ground with a parachute activity! Kids construct parachutes out of household items and a toy figure, after brainstorming the best way to reduce drag. Once they test their parachutes, they can adjust their projects to...

NASA's LCROSS mission is dropping a probe into a lunar crater. Groups design a system to travel down a zip line and drop a marble onto a target in the classroom. The groups then modify their designs based upon testing. 

Has your class wondered how fast a human could run or how high they are capable of jumping? Help them understand these concepts as they explore acceleration and use an accelerometer to make semiquantitative measurements of acceleration...

This Discovery Education activity provides the information needed to understand the basics of flight. Before taking off, young pilots learn the eight stages of the engineering design process. Small groups then design and build...

Investigate light in space as it encounters a large mass of matter. Learners discover the idea of gravitational lensing through an interactive activity. They adjust the size and location of the mass to see the effect on the path of...

There's more to fluids than meet the eye—they include gases, liquids, and polymers, too! Scholars complete three hands-on activities exploring different properties of fluids. They explore viscosity by measuring the resistance, or...

How hard do you need to throw a ball in the air so that it never returns? Scientists call this measure the escape velocity. Classes can explore this concept through an intriguing interactive lesson. Pupils adjust velocities and observe...

You won't have to force your classes to complete these engaging activities! Through exploration, young scientists learn that force has both magnitude and direction. They draw force diagrams, investigate force models, and complete a...

Most people realize they would weigh less if they were on the moon, but does it change how much weight you could lift if you were on the moon? Scholars adjust the mass of an object to be lifted and select between four different...

Everything that happens is an interaction, from the wind blowing a sail to a cannon ball being thrust out of a cannon. A simulation shows the interactions involving a sail, air, ball, pirate, cannon, deck, ocean, and the Earth and...

Air, air, everywhere, but what's in it, and what makes Earth's air so unique and special? Journey through the layers above us to uncover our atmosphere's composition and how it works to make life possible below. Pupils conduct...

To show the magnitude and direction of all forces acting upon an object, scientists use a free body diagram. This simulation serves as an introduction to free body diagrams allowing scholars to build their own. Pupils select the proper...

Build a bridge to learning in a STEM-aligned unit about urban infrastructure. Young engineers explore the many aspects of civil planning and design in a five-day unit. Content includes the challenging aspects of balancing building with...

Sometimes low, sometimes high, but always in motion! Explore Earth's tidal system in the 10th interactive in a series of 13. Engaging life and earth science students alike, the versatile resource demonstrates cause and effect between...

Up, down, back, and forth. When you make a pendulum out of a spring, there's a lot to observe. Aspiring masters of motion examine the combined kinetic energies of spring and pendulum motion using a detailed interactive. Learners observe...

Here's a resource with more bounce for the ounce! Engage your physical science class with an interesting interactive that allows individuals to perform tests with a mass attached to a spring. Participants can customize the scenario by...

Add some zing to your swing! Explore pendulum motion through an engaging interactive. Physical science scholars specify the pendulum's mass, rod length, and starting angle before they observe the resulting angle graph.

Launch pupil interest in rockets. Scholars build rockets out of straws and balloons to learn about Newton's Third Law of Motion. Their task is to hit a target five feet away. It's not as easy as it seems!

Here's a lesson that is simply a-MAZE-ing! Introduce science scholars to pipeline systems through a hands-on project. Partnered pupils participate in the design, construct, and test a PVC pipeline maze. Reusable materials and clear...

It's all uphill from here! Scholars examine the pattern of random particle motion up a staircase. The simulation shows how the linear increase in energy corresponds to an exponential decrease in particle concentration.

Can you determine how far down a rock drops without visual clues? Viewers observe a clip from a movie testing vertical distance only based on sound. They must determine if it is safe to drop down themselves or if it is farther than their...

How can you determine the height of a drop off a cliff if you have nothing to measure it with? A movie clip sets up a sky-high challenge and solves it with a falling glow stick. Scholars must take the given information and decide how...
