Elementary School, Space Exploration Science Projects (23 results)

Space exploration is an exciting and wide-ranging area. Getting into space (and back down) is hard, involving rockets and launch vehicles, satellites, spacecraft, re-entry systems, landers and rovers, robots, and orbital mechanics, not to mention hypothetical technologies like space elevators and artificial gravity. To survive and thrive in space, we must understand many additional issues such as human performance in space, the space economy, and the science of astronomical bodies.

Baking Soda and Vinegar Rockets
Science Fair Project Idea
Scientific Method
Watching a spacecraft launch is an amazing experience. It is thrilling to see it lift off and escape Earth's gravity. Did you know that it takes a chemical reaction to get a spacecraft into space? Every time you see a one blast off, you are watching chemistry at work. In this chemistry science fair project, you will also get to blast an object into the air. You will not be using the same fuel that NASA uses for the rockets that launch their spacecrafts; instead, you will use two simple… Read more
Rocket Catcher Challenge
Science Fair Project Idea
Engineering Design Process
Inspired by real-world reusable rockets, in this engineering challenge, you will design and build a device to catch a falling rocket so it lands vertically. Drop the rocket from higher and higher heights to get a better score! The 2025 Science Buddies Engineering Challenge is over, but you can check out this page to see our other past engineering challenges and what this year's challenge will be! Teachers, lesson plan versions of this challenge are also available. Read more
Asteroid! Identify Space Hazards with Computer Vision
Science Fair Project Idea
Engineering Design Process
Space is a dangerous place for astronauts and spacecraft. Earth's orbit is full of potential hazards like meteoroids, space debris, and other satellites that you do not want to crash into! How do scientists detect these objects in space? If you do detect an object, how can you tell what it is? In this project you will make your own computer program that can recognize and react to three different models of objects that can be found in space. No previous programming experience is required!

What's The Best Way to Land a Model Rocket?
Science Fair Project Idea
Scientific Method
What's the best way to land a model rocket? What makes the rocket hit the ground safely at a low speed? What prevents the rocket from drifting too far if it's windy? In this project, you will make your own rockets from paper towel tubes and drop them to test different recovery methods like parachutes and streamers. What method do you think will work the best?  Read more
Parachutes: Does Size Matter?
Science Fair Project Idea
Scientific Method
How does a parachute work? Do bigger parachutes work better than smaller parachutes? Find out in this science project if the size of the parachute matters. Read more
Bottle Rocket Blast Off!
Science Fair Project Idea
Scientific Method
3... 2... 1... 0— blastoff! In this science project, you will use a bottle rocket launcher to launch your own bottle rocket. You will load it with water and pressurized air, make several launches, and find out what makes your rocket soar the highest. Read more
How Does Speed Affect Orbiting Altitude of Satellites?
Science Fair Project Idea
Scientific Method
The movement of satellites is intriguing, but how do they orbit the way they do? Aerospace engineers run calculations and set up computer models to help them predict how satellites move in space, but in this astronomy science project, you will create a physical model with marbles, clay, and a cookie sheet to help you study how satellites move in space and learn from your observations. Read more
Model Rocket Aerodynamics: Stability
Science Fair Project Idea
Scientific Method
What keeps a model rocket on course? How can you make sure a model rocket design is stable before you launch it? Find out in this project as you learn about center of mass, center of pressure, and their effect on a rocket's stability. Read more
Motor Imagery Visualization's Impact on Fine Motor Skills for Space Flight
Science Fair Project Idea
Scientific Method
In this science experiment, you will model and test how visualization of a task can change the accuracy of your fine motor skill performance. You will use the small muscles in your hands to model how your body would perform on Earth versus a space launch. Read more
Astronaut Stress Management Training for Space Flight
Science Fair Project Idea
Scientific Method
Training for space flight isn't just a physically demanding job. You need to be prepared mentally and emotionally, too! In this science project, you will test how a breathing technique can improve your fight-or-flight response induced by the stressors of space flight. Read more
