3rd - Endless Energy

Now that we're experts in wiring electrical circuits, we investigated the Law of Conservation of Energy. That's a mouthful that basically tells us that energy is never created or destroyed.

The student wired a simple circuit with a light and observed how energy changes from stored energy in a battery to electricity to light and heat.

Then they removed the light and replaced with with a small buzzer motor.

Ask your student what kinds of energy were observed with the buzzer motor: motion (kinetic), sound (also kinetic) and heat (from the friction).

I wish you all a very safe and fun holiday break. In the new year, we will embark on the study of animals, the solar system and plants.
