When the car's axle is turned, the rubber band is stretched, and potential energy in the form of elastic energy is stored. With the Build a Rubber Band-Powered Car activity, students build a car that is powered by the energy in a rubber band. Questions: Do the rubber bands fly farthest when they are pulled back more or when they are pulled back only a little bit? Is the distance the rubber bands fly at each stretch length consistent? What forces act on the rubber band as it flies through the air? This activity introduces equations for both potential and kinetic energy and allows students to see firsthand that the distance a stretched rubber band travels is related to the distance it is stretched. In the Rubber Bands for Energy activity, students stretch and release rubber bands and investigate the relationship between how far the rubber band is stretched and how far it flies. Elastic energy is potential energy that is converted into kinetic energy when the stretched or deformed object is released.īecause of their stretchiness (elasticity), rubber bands are often used to demonstrate elastic energy. Elastic EnergyĮlastic energy refers to the energy stored in a stretched rubber band or other substance that is deformed and wants to return to its original shape. In exploring potential energy, students learn about elastic energy, gravitational energy, chemical energy, and nuclear energy. Sometimes thought of as the energy of an object at rest, potential energy is the stored energy an object has due to its position relative to other objects or due to deformation of its own shape. Student projects that appear below contain experiments that can be effectively adapted for use by educators for teaching about the topic. Activities are simplified explorations that can be used in the classroom or in informal learning environments. Lesson Plans offer NGSS alignment, contain background materials to boost teacher confidence, even in areas that may be new to them, and include supplemental resources like worksheets, videos, discussion questions, and assessment materials. Note: Science Buddies Lesson Plans contain materials to support educators leading hands-on STEM learning with students. The resources below are grouped as follows: Lesson Plans and Activities to Teach About Energy In these lessons, students explore the relationship between types of energy, conservation of energy, the relationship of energy to work, and how work can transfer or change the energy of an object.

The free STEM lessons and activities below provide hands-on learning materials to teach students about energy and to explore various types of energy and how they relate to other types of energy. In these lessons, students explore forces, what happens when one object does work upon another object, the role of mass and gravity, and how energy can be harnessed, converted, shared, and transferred. The lessons below help educators teach about the various types of potential and kinetic energy and about mechanical energy, the sum of potential and kinetic energy in a mechanical system. There are, however, many forms of energy that fall within the broad categories of kinetic energy and potential energy. Many students are familiar with potential and kinetic energy to describe the energy of an object at rest or in motion. The energy of an object may shift form, be converted or transformed into other types of energy, or be transferred to another object (or objects), but the total amount of energy in the universe remains the same.

According to the law of conservation of energy, energy cannot be created or destroyed. The law of conservation of energy is a fundamental principle of science. Teaching students about the law of conservation of energy and helping them identify the specific type of energy demonstrated by objects or systems offers a wide range of hands-on learning opportunities as students build their understanding and awareness of the science of energy. Students may identify the presence of potential and kinetic energy in the movements of a roller coaster, a pendulum, or a playground swing, but there are a number of different types of potential and kinetic energy.

The world is full of energy, and energy is constantly being used, converted, and transferred between objects. From the classic snake-in-a-can prank to stretching and shooting rubber bands across the room, bouncing a basketball, or rolling a marble down a ramp, kids know energy in motion when they see it.
