Here's an interactive with real potential ... potential energy, that is! Scholars analyze scenarios, then rank objects in order of greatest to least kinetic energy, potential energy, and speed. The interactive provides support materials,...

Just a swingin'! Introduce physical science scholars to the energy forms associated with a pendulum using a simple interactive. Learners adjust the height from which the pendulum starts, then observe changes in potential, kinetic, and...

There's more to melting than meets the eye! Junior physical chemists investigate the differences between specific and latent heats as a substance undergoes a phase change. Users remove heat from the system and observe changes in kinetic...

Physics class has its ups and downs ... especially when it involves energy concepts! Scholars analyze information to determine changes in kinetic and potential energy using an interactive resource. Realistic scenarios make connecting...

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...

How much energy in Jewels does it take to tow a car up a slope? Scholars explore different values of both kinetic and potential energy to answer that question. Through multiple levels, the difficulty increases — as does your young...

What happens inside a melting solid? Prospective physical chemists observe a solid-to-liquid phase change at the molecular level using an inspired interactive. Pupils add heat to a close system, then monitor changes in kinetic and...

Roller coasters rely on both kinetic and potential energy, but how much total energy does a roller coaster need? Scholars vary the mass of a coaster and the height of the initial hill. Graphs showing the types of energy and total energy...

What are the three types of energy a ski jumper uses? If you said potential, kinetic, and heat, then you are correct. Scholars adjust the jumper's mass, jumper's form, and height of the start line in the simulation to display graphs of...

Does a trampoline use mostly potential or kinetic energy? Pupils adjust the mass of the jumper, stiffness of the trampoline, and initial jump height in order to answer that question. The simulation displays graphs of the various types of...

Where does the energy of an arrow come from? Is it from the person, the bow, or somewhere else? A simulation allows scholars to adjust the stretch distance and the elastic constant in order to understand where the energy comes from, what...

Electricity travels at the speed of light, 186,000 miles per second. Through a simulation, classes see how the structure of energy bands in crystals of atoms determines how materials conduct electricity. Participants can change the...

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...

How does a neon light work and does it actually contain the gas neon? An enlightening simulation encourages pupils to play with circuits and neon lights. They control the capacitance, resistance, and color of the bulb, and the simulation...

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...

In this energy instructional activity, students read articles on the internet about energy and answer short answer questions. Students answer 10 questions total.

Why do some buildings have lightning rods? Scholars explore the movement and attraction of opposing electrical charges through a simulation of a lightning rod. They control the cloud height, charge separation, and if the lightning rod is...

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...

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...

The camera flash works based on a simple circuit, but why does it require a capacitor? Scholars work through two levels of simulations related to circuits and capacitors. The pupils first use a simple circuit with a battery,...

In this online interactive literature learning exercise, students respond to 20 short answer and essay questions about Edwidge Danticat's "Breath, Eyes, Memory." Students may check some of their answers online.
