Model Water Flow in Rivers

Science Fair Project Idea

Scientific Method

Have you ever seen a river from far above? It is fascinating how they carve their way through the landscape. But what makes the water in a river flow? Where does a river start and end? And why is it that rivers usually have lots of turns or bends and almost never flow straight? In this science project, you will make river models using aluminum foil and water to explore how water flow inside a river changes based on its shape. Read more

Modeling Your Local Watershed and Nutrient Pollution

Science Fair Project Idea

Scientific Method

Have you ever been unable to swim in a body of water because it was polluted? Have you ever wondered where the water came from, or what contributed to its pollution? In this science project, you'll learn how water drains to common areas to create bodies of water and how the land surrounding a waterway can contribute to its health and pollution. Read more

Modifying a Car for Better Aerodynamics

Science Fair Project Idea

Scientific Method

Have you ever seen those cool wind tunnel pictures of cars with streams of smoke blowing over them? You do not need access to a wind tunnel to do a car aerodynamics science project! In this project you will use cheap, readily available materials—tape and yarn—to visualize airflow over a car. You will examine how you can affect the airflow over the car by making changes, like adding or removing accessories or making body modifications out of cardboard and duct tape. Maybe you can… Read more

NASA Asteroid Database: What Can You Learn About Our Solar System?

Science Fair Project Idea

Scientific Method

Did you know that in addition to the Sun and planets, our solar system is filled with millions of asteroids, which are chunks of rock left over from the early days of its formation, or from collisions between larger objects like planets? Agencies like NASA track asteroids, not only because they might pose a threat to humanity by colliding with Earth, but because they can provide us with information about the history of our solar system, and even be useful for mining raw materials in space! In… Read more

New Bristlebot Science Kit for Student Robotics!

Blog Post

Above: The Brushbot is one of the three robots kids can build using the Bristlebot Kit from the Science Buddies Store. A brand new Bristlebot Kit launched today in the Science Buddies Store. With this new kit, students can experiment with three styles of introductory robots and learn more about robotics engineering. The kit has been specially designed to make building the robots easier for students to do independently—and fun! The new Bristlebot Kit contains components for use with… Read more

Now Playing: The Perseid Meteor Showers

Blog Post

Stay up late, or get up really, really early to catch nature's annual fireworks display. Students and families can extend Perseids fun with a hands-on science exploration of parallax. How far away are the things we see in the sky? By Kim Mullin Each August, a much-anticipated nighttime show plays live in our skies: the Perseid meteor showers. This annual event offers you the year's best opportunity to see meteors streaking across the sky, so long as you are willing to be awake well… Read more

Now You See It, Now You Don't: A Chromatic Adaptation Project

Science Fair Project Idea

Scientific Method

This project shows that our perceptions can change, even with the stimulus remains the same. A clear color difference in an image disappears after just 20 seconds of looking at another (special) image. Now you see it, now you don't! Read more

Ow, My Tummy Hurts! The Biology and Chemistry of Gas Relief

Science Fair Project Idea

Scientific Method

Have you ever wondered why bubbles form when you mix soap and water? Is it possible to mix soap and water without making bubbles? Medical doctors actually study similar questions when they treat patients who have too much gas trapped in their digestive system, which can cause pain and bloating and also signal a serious medical problem. Some drugs, including one called simethicone, can help relieve extra gas in the digestive system. In this science project you will find out how simethicone… Read more

Paper Rocket Aerodynamics

Blog Post

Make paper rockets you can launch by blowing through a straw and experiment to find out how changing the design can change how the rockets fly with this family STEM activity. Making a paper rocket that you can launch by blowing through a straw is an easy hands-on activity sure to engage paper airplane folders and rocket enthusiasts alike. You can easily turn this paper-based pastime into a STEM activity by exploring the design of the paper rocket. What… Read more

Planet Hunters TESS

Science Fair Project Idea

Scientific Method

The Transiting Exoplanet Survey Satellite (TESS) is a space telescope for NASA's Explorers program, designed to search for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission. It was launched on April 18, 2018 atop a Falcon 9 rocket. During its two-year primary mission, it was expected to find more than 20,000 transiting exoplanets, compared to about 3,800 exoplanets known when it launched. The first light image from TESS was taken on August… Read more
