Did you know that there are about 10,000 different types of birds in the world? You don't have to go far to see some of them. Birds live outside in backyards and parks and can even be found in a busy city! Do you know what kinds of birds live in your neighborhood? Have you ever taken a close look at the birds you see in your backyard to identify them and observe their behavior? In this activity, you will build a bird feeder to attract birds, so you can study them. Read more

Build a Model Planetary Lander with micro:bit

Science Fair Project Idea

Engineering Design Process

How do you make a spacecraft land safely on the Moon or another planet like Mars? It probably helps to know how far away the ground is so you can deploy landing gear, activate a parachute, or fire thrusters to help slow down. In this project you will build your own "lander" vehicle with a sensor that can measure distance to the ground, allowing you to program outputs like blinking lights or an audible alarm. Read more

Build a Solar-Powered Bristlebot

Science Fair Project Idea

Scientific Method

You have probably heard about using renewable energy sources like wind and solar power to provide electricity to homes and buildings, as well as hybrid or fully electric cars that use less (or zero) gasoline. But what about solar-powered robots? As robots become more common, it is increasingly important to use "green" energy sources to power them. In this project, you will build and test a popular robot called a bristlebot — a tiny robot made using toothbrushes—that can operate on… Read more

Can Exercise Really Make Our Brains Work Better?

Science Fair Project Idea

Scientific Method

"Use it or lose it!" Sure, we all know physical exercise is important to keeping our bodies fit. But how important is physical exercise to your brain? In other words, is there any connection between an active body and increased brain power? This is an easy project where you can test the effect of exercise on a critical brain function: memory.

Can You Predict a Bird's Lifestyle Based on Its Feet?

Science Fair Project Idea

Scientific Method

Animals survive in all sorts of extreme environments, whether it is a polar bear out and about when it is -40°F, a desert iguana trying to find food as the temperature rises to 110°F, or a deep sea anglerfish living 3281 feet down into the sea. How do they do it? The answer is adaptations! Their bodies have special features that allow them to live in those environments. You might not be able to dive down 3281 feet to observe the deep sea anglerfish, but in this science fair project you… Read more

Act like a geologist in this fun activity as you drill "core samples" from candy bars using a straw. Can you identify the type of candy bar just from a sample? Try this activity to find out! Read more

Candy Snap

Science Fair Project Idea

Scientific Method

Have you ever broken a candy bar in half to share with someone? Some might snap in half quite cleanly, but others might be gooey and flexible. If you stick a candy bar in the freezer, will this change how the materials break? Try this sweet project to find out! Read more

Catching Stardust

Science Fair Project Idea

Scientific Method

How do astronomers collect stardust? They design and build satellites that are launched into space to collect particles on specially designed panels. Satellites can be sent to orbit around an object of interest: a planet, moon, or comet. In this experiment, you can build your own mini satellite and use it to collect some pretend stellar debris. If you simulate an asteroid impact, how much stellar dust will your satellite collect? Will placing your satellite at different "orbital" distances from… Read more

Centripetal Force

Science Fair Project Idea

Scientific Method

What keeps you in your seat of a giant loop-de-loop roller coaster? Surprisingly, it is not the seatbelt but the seat! It works because of something called centripetal force and it does much more than make a great roller coaster. It keeps a satellite in orbit and you in your bicycle seat during a turn. How does it work? Read more

Chemistry of Baking Ingredients 1: How Much Baking Powder Do Quick Breads Need?

Science Fair Project Idea

Scientific Method

If you like to bake, this could be a good science project for you! Have you ever wondered about the purpose of each of the ingredients in your favorite recipes? For example, why is baking powder used in some muffin recipes? How does the baking powder affect how the muffins look, feel, and taste? In this food science project you will use a scientific method to find out! Read more
