Balloon Science Activities
Engaging student science doesn't always require specialty materials. All of the projects in this K-12 hands-on science project roundup use balloons!
K-12 Science Projects and Activities
Balloons can be used in a wide range of student hands-on science projects. From powering a car or propelling a hovercraft to enabling exploration of rocket science, kids can experiment with physics, aerodynamics, and more using ordinary balloons.
The following Science Buddies projects and activities use balloons:
- An Uplifting Project—The Buoyancy of Balloons: experiment to find out how quickly balloons lose their lift over time.
- Balloon Morphing: How Gases Contract and Expand: investigate how gases expand and contract with temperature.
- Balloon Car: explore the engineering design process and kinetic and potential energy by building and racing balloon-powered cars. (Lesson Plan)
- Balloon-Powered Car Challenge: design and build a balloon-powered car that will travel as far and fast as possible. You can use Google's Science Journal app with this project for added tech fun!
- Cartography: Projecting the Globe on a Rectangular Map: use a balloon to help students understand how mapmakers create flat maps of the spherical Earth. (Classroom Activity)
- How Does a Hovercraft Hover?: build a mini hovercraft and investigate how the amount of air in the balloon affects how long the hovercraft hovers.
- Racing to Win That Checkered Flag: How Do Gases Help?: explore the science behind why race car tires are filled with nitrogen gas.
- Rubbing Up Against Static Electricity: see how the number of times you rub wool on a balloon increases or decreases how long the static charge will last.
- Two-Stage Balloon Rocket: build a multi-stage balloon rocket and explore rocket science and Newton's laws of motion. (Lesson Plan)
