Parent and Teacher Notes

This experiment helps explain solar energy to your child by showing how solar panels convert sunlight into electricity. Sunlight is an important source of renewable energy, and solar panels can help turn sunlight into enough electricity to power a home.

Scientific concepts covered:

Renewable energy: A type of energy that doesn’t harm the environment. It uses resources that nature can replenish, including sunlight, water, and wind. It is different from fossil fuels, which can’t be replenished as fast as we use it up. It also doesn’t pollute the environment, unlike coal or oil which release harmful gases when they burn.

Silicon: A type of semiconductor found in sand and rocks. It is poor at conducting electricity but can absorb sunlight. In solar panels, silicon is mixed in with other chemicals called impurities to help it conduct electricity better.

Atoms: Atoms are the smallest building blocks of matter in everything that exists around us. When atoms bond, they can become molecules.

Circuit: A complete path through which electricity can flow. There are circuits inside electrical devices and homes. Circuits are how electricity can flow through our lights and electrical devices, allowing them to be turned on.
