Everglades Airboat
How does an airboat move when there isn't a motor in the water? The simulation teaches the forces related to the thrust and drag on an airboat. Scholars vary the boat mass and thrust force in order to view graphs of the changing force...
CK-12 Foundation
Pirate Ship
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 the...

Ballistics Tests
How did scientists measure the speed of incredibly fast things before the invention of high-speed photography? Scholars virtually perform ballistics tests to discover the process. They control the rifle type, bullet mass, and target...
CK-12 Foundation
Astronaut Training Chamber
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 locations...
CK-12 Foundation
Loop-the-Loop
What prevents a roller coaster from falling when it goes upside down? Scholars experiment with a roller coaster simulation controlling the mass of the coaster, the height of the hill, and the radius of the loop. They learn which factors...

Malt Shop
How does the soda clerk know exactly how to get the glass across the counter to the customer? Pupils use the simulation to adjust the launch velocity, glass weight, base area, surface material, and the customer's position to answer that...
CK-12 Foundation
Airplane
How does an airplane control its take off and descent? Scholars explore the forces acting on an airplane and control the angle of attack, wing profile, thrust, and airplane size. They learn about lift, drag, thrust, gravity, and the...

What's the Matter?
What makes ice, water, and steam different? Their molecular arrangements are the same, but their movements are different. Individuals make this conclusion by completing the simulation activity.
CK-12 Foundation
It's Just a Phase
Explore the phases of water as temperature rises. Pupils consider the idea that temperature remains constant during each phase change. An interactive exercise allows your young scientists to observe the temperature and molecular motion...
