Energy – Types and Uses

Published on August 28, 2022 by

Energy drives everything in our lives. Even simple actions like breathing or blinking require energy. In this lesson, students will learn about energy, its types, sources, uses, and conversion of energy. The main types of energy include heat, light, chemical, electrical, and mechanical energy. In nature, sources of energy include solar, water, and wind. Depending on the ability of an energy source to replenish itself, it can be classified as renewable or non-renewable. Examples of renewable energy include solar and tidal energy, while non-renewable energy includes the energy from fossil fuels. Bear in mind that energy cannot be created or destroyed, but can only transfer from one form to another. Therefore, all our activities are fueled by energy transfer. For instance, chemical energy from food is converted to muscular energy, which allows us to move.

The video satisfies the 4-PS3-2 requirement of fourth-grade science proficiency.

Students who demonstrate understanding can: 4-PS3-2. Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.
