Making learning fun is sometimes half the battle! With the right activities, educators can ensure learning about science and engineering involves hands-on fun for students of all ages. Build in some stretchy science fun with STEM experiments that use rubber bands!
Stretchy STEM Science!

Rubber bands are fun to stretch. What happens when you let them go? They might fly! Can you use the stretchiness of a rubber band to send other things flying or create sound waves? Can you learn about energy from rubber bands? Yes!

Students can learn a lot about potential and kinetic energy-and the law of conservation of energy-from simple rubber bands. In this week's Educator's Corner, we've highlighted an assortment of exciting maker-inspired builds and experiments that use rubber bands. From launchers and a rubber band-powered car to noisemaking fun with a rubber band guitar or craft stick harmonica, these are STEM-based activities your students will love.

Let's hear it for stretchy rubber band science!

Our Educator's Corner series features high-interest STEM activities that work well with students in both formal and informal settings-in the classroom or at home. These activities are grouped in fun themes that make it easy for educators to pick and choose just-right activities for special days or special units. Each collection is hand-curated for fun, ease-of-use, simple materials, accessibility, and interest factor. To help educators bundle activities with additional classroom or out-of-class activities and reflection, we've included discussion questions, career connections. We've also included book suggestions to help educators tie science and engineering to English Language Arts.

EXPERIMENT: STEM Experiments with Rubber Bands

The science: The launcher stores elastic potential energy that is converted to kinetic energy that propels the cotton ball when the rubber band is released.

The science: When the propeller is wound, it stores elastic potential energy that is converted to kinetic energy when released.

The science: The stretched rubber band stores potential energy that will be converted to kinetic energy to propel the plane forward when the rubber band is released. Designing a device that can stand up to repeated use will take trial and error, troubleshooting, and problem solving!

The science: When the launching stick is pushed down, it has potential energy, just as a rubber band does when it is stretched. When the stick is released, the energy is converted to kinetic energy which is transferred to the object being launched.

The science: When the axle is wound, potential energy is stored. When the axle is released, the energy is converted to kinetic energy that propels the car forward.

ASK: Questions

Use these questions with students to prompt conversation and reflection about the science behind these Rubber Band STEM activities:

Does an unstretched rubber band have energy?

What type of energy are you creating when you stretch a rubber band?

What happens when you release a stretched rubber band in terms of its energy?

What are other examples of potential energy?

What is the law of conservation of energy?

CHOICE BOARD: Differentiated Learning

Choice boards offer a flexible learning tool educators can use to supplement classroom instruction. You might try a choice board as part of weekly homework, for extra credit, or for asynchronous and remote learning.

Lab: Rubber Band Energy

Duration: Approximately 50 minutes

This lab is an investigation of the relationship between kinetic energy and potential energy. Students will measure the kinetic energy released by a stretched rubber band.

LEARNING OBJECTIVES

Students will look for an observable relationship between kinetic energy and potential energy.

Teacher Tips

The actual energy transfers during the experiment consist of:

a) storing potential energy in a rubber band;

b) releasing it as rubber-band kinetic energy;

c) transferring a fraction of that kinetic energy from the rubber band to the half-cup, and;

d) dissipating the half-cup kinetic energy by air and surface friction.
The relationship of rubber-band extension to potential energy is quadratic, and the relationship of half-cup movement to kinetic energy is not easily modeled. If the goal is to connect the potential energy of a spring to kinetic energy, that connection is implicit in the fact that the rubber band moves when it is released; one could simply shoot it upward and see how high it goes if a quantitative test is wanted.

Materials (per group)

a rubber band

a paper cup sliced in half lengthwise (plastic and Styrofoam cups can also work)

a ruler

Safety Checks

Review with your students all your school's safety protocols when doing labs.

Rubber bands should be pointed only inside cups.

Cups should be positioned so that no student (or teacher) can get hit by wayward rubber bands that miss their targets.

Flying rubber bands can cause injuries, especially to eyes. Consider protective goggles.
