Electrical phenomena are important and widespread in the natural world, and often occur unnoticed in our daily lives. This unit builds student understanding of the movement of energy at the electron level to creates the electricity that powers our world. Electrical energy (charge, voltage, current, resistance, conductivity) is explored via hands-on activities using basic circuits; and the relationship between power grids and blackouts examines our reliance on electricity.
Engineers build upon their scientific knowledge of energy and electricity concepts to provide us with electricity to meet our basic needs of food, shelter, safety, heating and cooling, as well as luxuries of comfort and entertainment. Engineers work with energy and electricity in all its forms—from atomic-level electrons to nation-spanning electrical power grids.
