This lesson facilitates the process of creating circuits using a squishy circuits kit. Topics covered in this lesson include circuits, conductors, and insulators.
The speed at which sound travels from one place to another depends upon the medium and how closely packed the molecules are in the matter. Learn more about how sound travels from the simulation.
The Sun is a natural source of visible light waves. Our eyes see the reflection of the sunlight off the objects around us. Check out the simulation to learn more about scattering light.
When you flip a light switch on and off, you are closing and opening a circuit. A circuit is the path that electricity follows. Play the interactive above to learn more.
