Ohm's Law
Why did Mr. Ohm marry Mrs. Ohm? He couldn't resistor. An electrifying simulation allows scholars to control both voltage and resistance in order to see the current change. The formula is displayed and as you increase one variable, it...
Laboratory for Atmospheric and Space Physics
Orbit Simulator
Researchers think they have evidence of a new planet deep in our solar system that is the size of Neptune and orbits the sun far beyond Pluto. The orbit simulator shows the orbits of our well-known planets, as well as Pluto and the comet...

Power Lines
How does electricity travel through power lines? The simulation demonstrates the how changes in voltage and resistance are related to the distance between power polls and the thickness of the cable. Scholars control three variables in...
CK-12 Foundation
Electric Motor
How does a direct current run a motor? Pupils control five variables in an electric motor and observe how the force diagram changes. The force, magnetic field, and current vary based on the changes in the design of the magnet and...

Sprinter
Why do sprinters wear spiked shoes? Scholars explore various styles of shoes and how they handle forces when running. Scholars adjust variables including shoe type, horizontal force, surface type, and normal force to determine which...
Learning Games Lab
Testing for Corn Mold
Learners complete a virtual lab to test for a corn mold that can lead to dangerous toxins. They walk through a detailed step-by-step procedure then see their findings. Throughout the activity, they learn how to use lab tools and practice...

Biodiversity Debate - Stream Side Science
Role play community members who are both for and against the construction of a dam. Research the pros and cons and then hold a classroom debate. This activity ideally follows a series of stream studies, links to which are included. Use...
Magic of Physics
Wave Machine
Three main factors determine the wave height experienced in the ocean. Scholars use a virtual simulator to alter wind speed, fetch, and duration. Each combination creates a unique wave measured in significant height.

Newton's Apple
Scientists state that the higher something is above the earth, the greater the gravitational potential energy. Does this mean there is more gravity acting on the moon than on an apple falling from a tree? Scholars adjust the distance...
