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 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...

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...

Get energized! Circuitry scholars follow the path of energy from its beginnings as a fossil fuel all the way to bulbs and batteries using an interesting interactive. Groups or individuals help Ben Franklin discover how to convert and...

Teach budding mathematicians how to square a triangle with an interactive that shows a graphical proof of the Pythagorean Theorem. Pupils alter the lengths of the legs using sliders. Using the inputted lengths, the applet displays the...

In this online interactive philosophy learning exercise, students respond to 7 short answer and essay questions about the Gilded Age and Progressive Era in the United States. Students may check some of their...

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

In this electrical circuit learning exercise, students research the Federal Communication Commission to determine the regulations for a non-license radio transmitter. They will answer a series of another 3 questions to show an...

In this online interactive philosophy worksheet, high schoolers respond to 30 short answer and essay questions about The Birth of Tragedy by Friedrich Nietzsche.

This lab is designed to have students investigate the transformations that occur when elastic potential energy is converted to kinetic energy. Students will be able to modify the mass of the object, the spring constant of the spring and...

This program was designed as a quick graphing program that students could use on a computer, tablet or smart phone when a more complex graphing program is not available. This program will let students plot up to 10 data points and then...

The Quadratic Transformer was developed to support the learning of quadratic functions, and in particular to help you understand the connections between symbolic and graphic representations. Indirectly, it also helps you connect either...

Use animation and other interactive strategies to help understand physics principles. Change the track and height to see if your ball can make it to the end.

Understand the energy transformations that happens when you light a bulb with a battery. Activity requires students to build a simple circuit and take temperature and time measurements. Lab includes procedure with questions that can be...

[Free Registration/Login Required] Learn about how high-voltage alternating current (AC) electricity generated by a power station is converted into low-voltage AC electricity for your home using this interactive simulation. A PDF...
