69 Simple Science Fair Projects With Model Rockets

Are you looking for a fun, educational, and exciting science fair project? Model rockets are the perfect way to capture your audience's attention while teaching crucial scientific concepts. Austin Rockets is here to help you with 69 simple science fair projects that will surely propel your project to the top of the leaderboard!

1. Newton's Third Law of Motion

Explain and demonstrate how model rockets provide a perfect example of Newton's Third Law of Motion – for every action, there is an equal and opposite reaction – by building a small rocket and showcasing its launch.

2. Rocket Aerodynamics

Show how the shape and design of a rocket affect its flight, comparing different rocket styles and their aerodynamic properties.

Balancing Act:

  • Demonstrate the importance of balancing the rocket's weight to ensure it flies straight and stable.
  • Explain how unbalanced rockets may spin out of control or crash, affecting their performance.

Temperature Effects:

Explore the effects of temperature on the rocket's performance, launching rockets in various temperatures and analyzing their flight patterns and times.

3. Rocket Propulsion Systems

Compare and contrast different kinds of rocket propulsion systems, such as solid fuel rockets, liquid fuel rockets, and hybrid rockets. Detail the advantages and disadvantages of each type and discuss their applications, including in model rocketry.

4. Building a Model Rocket Engine

Construct a homemade model rocket engine using materials like potassium nitrate, powdered sugar, and PVC pipe. Explain the chemical reactions that take place during the engine's combustion and the role it plays in propelling the rocket.

5. The Recovery System

Design and compare different recovery systems for model rockets, including parachutes and streamers. Explain how these systems ensure the safe return of the rocket and its payload.

6. Model Rocket Safety

Discuss the importance of safety in model rocketry, addressing safe launch procedures, engine handling, and basic first aid measures. Emphasize the need for adult supervision and following the National Association of Rocketry's safety code.

7. Altitude Tracking

Demonstrate different methods for tracking a model rocket's altitude, such as using a clinometer, altimeter, or even a GPS device.

8. Launch Angle Optimization

Experiment with different launch angles to find the optimal angle for achieving the highest altitude or longest flight time. Explain the principles of trajectory and how it relates to the angle of launch.

69 Simple Science Fair Projects With Model Rockets Example:

Example Project: Water Rocket Launcher

Create a simple, reusable water rocket launcher using PVC pipe, a bicycle pump, and a two-liter soda bottle. This project demonstrates the principles of rocket propulsion and Newton's Third Law of Motion using water and air pressure.

Materials Needed:

  • PVC pipe
  • T-joint PVC connectors
  • Bicycle pump with a pressure gauge
  • 2-liter soda bottle
  • Duct tape
  • Water


  1. Construct the base of the launcher using PVC pipe and T-joint connectors, creating a stable platform for the bottle rocket.
  2. Attach the bicycle pump to the T-joint at the base, ensuring a tight seal with duct tape if needed.
  3. Fill the 2-liter bottle about one-third full of water and secure it to the launcher using duct tape, with the opening of the bottle facing downward.
  4. Pump air into the launcher system, building pressure inside the bottle. Monitor the pressure gauge and stop pumping when you reach around 40 psi.
  5. Stand back and release the pressure to launch the water rocket!

In conclusion, model rockets offer a fascinating and educational way to explore multiple scientific principles while creating impressive and memorable science fair projects. By choosing one of these 69 simple science fair projects with model rockets, you'll not only captivate your audience but also inspire the next generation of rocket scientists.
