Fantastic Fossilization! Discover the Conditions For Creating the Best Cast Fossils

Science Fair Project Idea

Scientific Method

Have you ever stood close to a fossilized T. rex skull and counted its razor-sharp teeth? Or, have you seen a fossilized stegosaurus skeleton and thought about how it defended itself with tail spikes and armored plates? A trip to a natural history museum lets you imagine what dinosaurs looked like and wonder what life with them on Earth was like. Fossils give us information about animals and plants that lived long ago. Certain places around the world contain more fossils than others. Why?… Read more

Fear Factor: Using Pulse Rate to Measure Emotion

Science Fair Project Idea

Scientific Method

Oh, were you ever scared! Your heart pounded, your breath rate shot up, your palms got cold and clammy. Fear does that to us. Here's a science project based on roller coaster rides to see if heart rate is an accurate measurement of fear. Are you brave enough to take on this frightfully fun project? Read more

Feeding Earthworms: Do Different Diets Affect Them and the Soil They Enrich?

Science Fair Project Idea

Scientific Method

Interested in helping the environment, and don't mind getting dirty? In this project you get to mix it up with earthworms, soil, and various types of organic kitchen scraps. The basic idea is to set up small earthworm colonies to compost different types of food waste. You test the soils in each type to see how diet affects both the earthworm population and the nutrients they put back into the soil. This project takes a little time, but it's worth it. You'll help the environment and learn… Read more

Field Goal! The Science Behind a Perfect Football Kick

Science Fair Project Idea

Scientific Method

Did you know that throwing, kicking, and punting a football all involve the science of projectile motion? A star NFL® quarterback, kicker, and punter each need to have a very good understanding of how a football moves through the air in order to help them win games. In this science project, you will set up a rubber band-powered catapult to represent a field goal kicker, and study how changing the distance from the goalposts affects how hard it is to accurately kick a field goal.

Fighting the Flu: How Your Immune System Uses Its Memory

Science Fair Project Idea

Scientific Method

Being sick is no fun, especially when your friends are doing exciting activities that you have to miss out on. Thankfully, common illnesses usually last for just a few days, and then you start to feel better. Why is this? It is thanks to the immune system, which is a group of special organs and cells in your body that constantly work to keep you healthy. In this science project, you will make a simple model to investigate how the immune system defends the human body from common illnesses, and… Read more

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
