Give youngsters the components of a solar-powered electric circuit and turn them loose to figure out how to connect them in order for a light to shine or motor to turn. They compare energy output of a solar panel to that of a battery. On...

What is the difference between a form of energy and a source of energy? This first activity in a series of 19 lessons uses demonstrations and discussions to introduce energy to the class. Through using hand-generator flashlights,...

Young scientists design a rocket to launch using Newton's Laws of Motion in order to discover for themselves the forces of motion. 

And thus the story ends. After a betrayal by her robot companion, the heroine of the story must find a way through a maze. Successful completion of the maze unlocks a crystal that will help save the world. By watching the video, pupils...

Linear equations are all about form. The fifth part in a unit of nine works with the different equivalent forms of linear equations. Class members become familiar with each form by identifying key aspects, graphing, and converting from...

Does a tennis ball have energy? What about a bowling ball? Demonstrate concepts of different forms of energy forms and states with a variety of objects. Using the equations for potential and kinetic energy, learners determine the amount...

A comprehensive lesson on acceleration awaits your physicists and engineers! Two YouTube videos pique their interest, then sample F=ma problems are worked and graphed. The highlight of the lesson is the building of a Lou-Vee air car!...

Even magicians can't make energy disappear. In a discussion-based lesson, young scientists learn about energy forms and conversions. They see how energy is neither created nor destroyed; it just changes forms. This is the 11th...

It's not so straightforward — lines can model a variety of applications. Pupils experience linear relationships within the context of science, including Hooke's and Ohm's Laws. Class members got a taste of motion and speed from the...

It's the law—every action requires a reaction, no matter how small. Pupils experience two demonstrations of Newton's third law of motion as it relates to thrust in the 10th segment of a 22-part unit on flight. Using their mathematical...
