Science Fair Project Idea

Scientific Method

"Swing me higher, Mommy, higher!" Kids love to ride the swings at the playground. The back-and-forth motion of a swing demonstrates the physics of a pendulum. In this experiment, you will investigate the factors that affect the speed and duration of a pendulum's swing, also called an oscillating motion. You can even use your phone and a sensor app to record your pendulum's movement and determine its period of oscillation. Read more

Something's Fishy About That Fertilizer

Science Fair Project Idea

Scientific Method

Did you know that when you use fertilizer in your garden, it can eventually reach a lake, stream, or pond? There are many different chemicals present in fertilizers. How will they affect the aquatic organisms in the ecosystem? In this science project you will get to find out! Read more

How Well Do Disinfectants Work?

Science Fair Project Idea

Scientific Method

Germs are everywhere! We try and clean our home with disinfectants, but do we really get rid of all the germs? Find out with this "hands-on" experiment. Read more

Changing Constellations

Science Fair Project Idea

Scientific Method

Do you like to look up into the night sky? There are so many stars, it can be mind boggling! Some ancient people marked time by the changes in star patterns. We still use changes in constellation patterns to mark astronomical time. Do constellations change more in one hour, one day, one month, or one year? Read more

How Do the Seasons Change in Each Hemisphere?

Science Fair Project Idea

Scientific Method

On a rainy day, do you ever wonder what the weather is like on the other side of the planet? Different regions around the globe can have very different seasonal weather patterns. In this experiment, you can test if these seasonal variations are related to which hemisphere each region is located in. Read more

Jumping Distance

Science Fair Project Idea

Scientific Method

Mike Powell of the United States currently holds the world record for the long jump at 8.95 meters, which is almost 30 feet! How did he jump so far? In this experiment, learn how a long jumper uses momentum from running to jump farther than the competition. Read more

Make the Fastest Rubber Band Paddle Boat

Science Fair Project Idea

Engineering Design Process

Rubber band paddle boats are a fun bathtub or pool toy that you can build yourself. How do you make a boat that goes the fastest? Find out in this project as you build and test your own boat. Read more

Primary Productivity and Plankton

Science Fair Project Idea

Scientific Method

Have you seen plankton? I am not talking about the evil villain trying to steal the Krabby Patty recipe from Mr. Krab. I am talking about plankton that live in the ocean. In this experiment you can learn how to collect your own plankton samples and see the wonderful diversity in shape and form of planktonic organisms. Read more

Milk Does Your Body and a Boat Good—Design Your Own Milk Carton Boat

Science Fair Project Idea

Scientific Method

Who'd have thought that drinking milk can lead to a pretty cool boat? Boat design is an important and active area of engineering. In this science fair project, you will design and build different kinds of model boats out of milk cartons. Examples of the types of designs you might test include a raft, a catamaran, and a V-shaped hull. Once the model boats are built, you will test key features, such as stability, maneuverability, and their ability to glide. Read more

How Does a Hovercraft Work?

Science Fair Project Idea

Scientific Method

Have you ever ridden on a hovercraft? It is like gliding on a cushion of air! In this science project, you will make your own mini hovercraft using a CD or DVD and a balloon and investigate how the amount of air in the balloon affects how long the hovercraft hovers. Read more
