You probably know that water never stays still. But did you know that there is something called the global “ocean conveyor belt” that moves massive amounts of water from one ocean to another? These water currents are essential for mixing and transporting nutrients and oxygen, and play a critical role in our climate. This is because they move warm and cold water over very long distances, which affects the temperature of the landmasses that border the ocean. The Gulf Stream, for… Read more

Find the Best Place to Put a Solar Panel

Science Fair Project Idea

Scientific Method

Imagine trying to put a solar panel on your roof or outside your home to generate clean, renewable energy. Where would you put it so it generates as much power as possible throughout the day? What direction should it face? Is there a way to take measurements to find the best location before you install the panel? In this project, you will use a tiny programmable device called a micro:bit to record light data and find the best place to put your panel. Read more

Find the Horsepower of a Toy Car

Science Fair Project Idea

Scientific Method

Have you ever heard someone describe how much horsepower a car has? Why do we use horses to measure how powerful cars are? What exactly is horsepower? How is horsepower related to things like speed and torque? Find out in this fun science project as you use a simple setup to find the horsepower of a battery-operated toy car. Read more

Finding the Center of the Milky Way Galaxy Using Globular Star Clusters

Science Fair Project Idea

Scientific Method

The Milky Way is the edgewise view of our home galaxy, a disk made up of billions of stars. The Sun resides on one of the spiral arms of the disk, 30,000 light-years from the thick hub of the galaxy. The actual center, with a black hole 3-4 million times the Sun's mass, is hidden by dust clouds in space. In this astronomy science fair project, you will use astronomical data to locate the center of this galaxy. Read more

Do you have a fire extinguisher at home? Hopefully, yes! It can save your life in case there is a fire. But have you ever wondered how these extinguishers work? Some of them don't even contain water, which is what you probably think of first when it comes to stopping a fire from spreading! What else other than water can extinguish a flame? Do this activity to find out—and put a candle out as if by magic! Read more

Fish + Food = Science of Aquaponics

Science Fair Project Idea

Scientific Method

How are we going to feed the more than 9 billion people that will live on Earth by 2050? This is a major question for farmers, ranchers, and food scientists around the globe. It's a big problem, considering that from 2017 to 2050 we will be adding 1.5 billion people and need 20% more food. Linked to this problem of producing enough food is having enough land, water, and other natural resources to make that happen. The final solution will surely be made up of many different approaches working… Read more

Have you ever wondered how a decision to move your arm can make your arm move? When your brain creates a command to move your arm, nerves pass along the command and muscles in the arm contract as ordered. These muscle contractions make your arm move. But could your arm move without a command from the brain? This activity is a fun and surprising way to find out! Read more

It’s fall, which means flu season. We all know that washing hands a few extra times a day can help keep colds and flu at bay, so we wash hands frequently and use a paper towel…then another one, maybe even three or four to dry them off. Because who likes to go out with wet hands in cold fall weather, right? But could there be a way to conserve some of that paper, and get a paper towel to go the extra mile, allowing you to dry your hands with just one single sheet? This… Read more

Football Field Goals: Going the Distance

Science Fair Project Idea

Scientific Method

When watching a football game, have you ever wondered why some kicks lead to a successful field goal and others do not? There are a lot of variables at play in a game of football, and many of them are related to physics. One variable that can affect whether a field goal is successful is distance. In this science project, you will explore how field goal success rate is affected by distance from the goalposts. What will be the best distance for you to kick some field goals? Grab a football, head… Read more
