In 1820, Hans Christian Orstead discovered the link between electricity and magnetism, which allows us to measure current and voltage. The simulation allows scholars to observe the inner workings of an ammeter and voltmeter as they...

Tommy is stuck in a dungeon and can only escape if you can discover the correct formula for velocity! Through trial and error, scholars enter the velocity required for Tommy to reach the elevator at the proper time. Then they extrapolate...

If your pupils think relative velocity is the velocity at which you can run away from your relatives, they need this simulation. Two bikers want to meet at a specific time. Scholars alter the velocity of one rider to arrange the...

What are some simple uses for an electromagnet? Scholars explore the electromagnetic circuitry in a doorbell through an interesting simulation. They control the core material, number of loops, amount of current, and strength in a spring....

How do we know how long ago a dinosaur lived or an ancient fire pit was used? Scholars learn about the application of carbon dating and half lives to discover things about the past. They adjust the amount of radioactive carbon in the...

Everything is made up of atoms, but what are atoms made up of? The simulation explores subatomic particles. It focuses on hadron, boson, and lepton groupings as scholars learn about quarks, neutrinos, gluons, and more.

We can see the result of electricity  but not the process itself. The simulation compares electric circuits to a water tower and water wheel cycle. Young scientists adjust the height of the tower, the amount of resistance, and if...

Can you time the speed of your car perfectly so you only hit green lights? The challenge in the simulation is to alter the timing of the lights or the speed of the car in order to do just that. Scholars learn about angular speed as they...

When a car crashes into a wall, does it just stop or does it bounce or roll backwards? A simulation relates velocity, kinetic energy, momentum, and restitution to answer this question. Scholars apply their knowledge through...

High voltage power lines deliver electricity to homes, but each home requires low voltage. How does the energy get converted so it can be used safely? Pupils explore alternating current and transformers through a simulation. They control...

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...

Did you know physicists can identify new particles by observing the path they take in a particle accelerator? Scholars explore the variables that determine the direction and radius of the circular path different particles take. They...

Stars are too hot to visit, so how do we know what different stars are made of? An enlightening simulation uses a spectrum graph to show the various electron emission and absorption reactions. Scholars experiment with both helium and...

What happens to radio waves, time, and light in and near a black hole? Young scientists explore what is known about observing frequency and time at various distances from a black hole. They control the size of the black hole and the...

What makes some elements stable and others radioactive? Scholars adjust the number of protons and neutrons in an element then observe its decay. The simulation includes a graphical representation and the chemical formula, as well as...

How can we use vectors to determine a person's position when traveling? The simulation offers guided practice at determining the coordinates and the distance between coordinates on a map grid. It reinforces the importance of positive...

What determines which ball rolls the fastest — the weight, the radius, the material, or something else? Scholars select two balls to race down the inclined plane, determining their material and radius. As they race, the simulation graphs...

Does Newton's First Law of Motion explain how to move a sled across ice? A simulation encourages scholars to decide if they should push, pull, or apply no force. Their decision moves a sled across the ice and to the home at the...

How much pulling force does it take to overcome static friction? The simulation applies the formula for the force of static friction to multiple trials. Scholars alter the pulling force applied until the box moves. They then determine...

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...

Keep calm and use the force! Joey pulls a cart and scholars adjust the force required to control the movement. Through simulating different scenarios, participants learn about Newton's Third Law. It includes analysis questions throughout...

Does the amount of a roller coaster's energy change as it goes along the track? Scholars investigate when a roller coaster has potential and kinetic energy. They observe the changes as it goes up the initial hill follows it throughout...

Tommy is trapped on an ice bridge and needs you to balance the charges so he doesn't fall into the icy water! Scholars apply Coulomb's Law, which relates to both the strength and the distance between charges. They work with these two...

Can you get the puck into the goal using only electric charges on the ice? Scholars experiment with electrostatic forces as they determine which charges pull the puck and which repel it. Multiple levels reinforce different related...
