Astrogeology

Science Fair Project Idea

Scientific Method

The same principles of geology that we use to investigate the Earth can also be applied to other planets. Visit the Astrogeology Research Program at the USGS to find out how information about the geology of other planets can be gathered (USGS, 2006). Can you make a map or model of another planet? What minerals are found on other planets? Which planets have similar composition to the earth? What kind of geological forces occur on other planets? Do other planets have earthquakes, landslides… 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

Attractants and Repellants

Science Fair Project Idea

Scientific Method

Animals respond to chemical cues in different ways. If an animal turns away from a chemical cue, then that chemical is a repellent. If an animal turns toward a chemical cue, then that chemical is an attractant. Attractants and repellents can be airborne chemicals, chemicals found in food, or chemicals that diffuse through water. One example of an airborne chemical is a pheromone, a chemical signal that is released by one individual to attract another. Moths release pheromones to attract… Read more

How do drones automatically balance themselves when you let go of the controls? Find out in this project as you build and program an experimental setup to make a drone automatically control its tilt angle about a single axis. See this page for a complete list of our mini drone projects. You may wish to do the projects in order. Read more

Back and Forth to Go Forward: A Snake on Wheels?

Science Fair Project Idea

Scientific Method

Have you ever ridden on a Roller Racer® or PlasmaCar®? These are ride-on toys that you move ahead by moving the steering mechanism back and forth. You've probably seen skateboarders "slaloming" on level ground to keep rolling, it's basically the same idea. This project explores the physics behind this method of locomotion. Read more

Background Bop: Do Different Businesses Play Different Tempos in Background Music?

Science Fair Project Idea

Scientific Method

Walk into a fitness club and what kind of music do you hear? Slow, sparkling, relaxing music? Or driving, "up-tempo" songs that are designed to encourage you to move? Fitness clubs and other businesses, like restaurants and grocery stores, use background music to set the mood and to determine how fast they want their customers to move. The tempo of the background music is a key component to the environment that businesses want to create. Tempo is an important number or word inscribed by a… Read more

Baking Soda Weight Loss

STEM Activity

Baking soda is not only great for cooking; it is also a useful chemical for science projects. You have probably heard about and maybe even used the baking soda/vinegar reaction to make volcanos erupt, shoot bottle rockets up in the air, or to detect acids and bases. However, there are many more chemical reactions that you can explore with the help of baking soda. One of them is called a decomposition reaction, which makes baking soda lose weight! Want to find out how it works? Then try this… Read more

What makes an object balanced? Look around you—most of the objects in the room are probably balanced and not on the verge of tipping over. If someone hands you an object and asks you to put it down, you probably know, without thinking about it too much, how to place it so it won't fall over. But what's the science behind how an object balances? Why do certain objects only balance on some sides and not others? Try this project to find out! Read more

Barometric Pressure and Weather

Science Fair Project Idea

Scientific Method

How does temperature change as barometric pressure changes? You can make a device to test this using a barometer and a thermometer on your stovetop. You can collect your own weather data from a barometer and thermometer over a period of a week or month. You can also use data from a weather station to plot the relationship between barometric pressure and temperature. Does the pressure change as humidity changes? Measure the pressure in a humid and non-humid environment (like your bathroom… Read more

Bat Detector: Listen to the Secret Sounds of Bats

Science Fair Project Idea

Scientific Method

Do you have bats in your neighborhood? Have you heard them "whoosh" by you, but not been able to see them? In this science fair project, you will be able to detect flying bats by listening in on the ultrasonic signals they produce to locate objects in their environment. The bat detector is a useful and fun tool for studying the biology of this nocturnal flying mammal. Read more
