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 Light-Tracking Bristlebot

Science Fair Project Idea

Scientific Method

Sometimes engineers get ideas to build robots from animals in nature. There are robot dogs, robot snakes, robot birds, robot cheetahs, and even tiny robotic insects! In this science project, you will build a robot insect of your own. The robot will automatically drive toward a light source, mimicking a behavior called phototaxis, seen in some insects. You will build your own robot and then make adjustments so it can reliably drive toward a light. Read more

Build a Motion-Activated Guard Robot (BlueBot Project #1)

Science Fair Project Idea

Engineering Design Process

Do you ever wish you could hire someone to guard your favorite toys, or keep certain people from coming into your room? What if you could make a robot to do it for you? This project will show you how to build a simple security robot controlled by a motion-detecting sensor. When someone comes near your valuables or enters the room, the robot will spring to life and (hopefully) scare them away! Read more

Build a Simple Steerable Robot

Science Fair Project Idea

Engineering Design Process

Beginner robotics projects like the Art Bot and Bristlebots are fun, but the robots wobble around randomly and cannot steer. If you are ready for a robotics project that is a little more advanced (that does not require any programming), try this one out! You will build your own steerable robot with a wired remote control.

Coke® & Mentos® - Exploring Explosive Chemistry!

Science Fair Project Idea

Scientific Method

You have probably seen it on You Tube™ — the exploding Coke® and Mentos® experiment. But what is it that makes the reaction happen, and what factors cause a larger or smaller eruption? In this science project, you will see if using crushed Mentos candies, instead of whole Mentos candies, will affect the reaction. Read more

Have you ever wondered why ice cubes in your cold drink become gradually smaller, or why their surface becomes smoother as they melt? Does ice always melt this way? In this activity, you will use water balloons to create giant ice balls and observe how they melt. Can you predict the effect a bit of salt will have on your giant ice ball? Read more

Crime Scene Chemistry: Determine the Identity of an Unknown Chemical Substance

Science Fair Project Idea

Scientific Method

Picture this situation: An elderly woman is rushed to the hospital complaining of severe abdominal pain, tinnitus, and lethargy. Suspecting a drug interaction, the emergency room doctor starts questioning her. The doctor learns that the woman takes no medicines except aspirin for her arthritis. Since she cannot swallow pills well she takes a powdered form of aspirin which she buys in bulk and keeps in a plastic container in her kitchen next to her baking goods. She had just finished a day of… Read more

Develop Your Own Soda Pop Recipe

Science Fair Project Idea

Scientific Method

Carbonated bevarages are quite popular in the United States (despite the health risks of drinking too much of the sugary ones). Many people love their bubbly, fizzy flavors. But how do the bubbles, fizz, and taste get into the water? In this cooking and food science project, you will work with baking soda, citric acid, and sweetener to create a your own soda pop. Once you develop your recipe, try it out on your friends and family. Who knows? You might create the next soda pop sensation! Read more

How do drones automatically hover at a constant distance from the ground? Find out in this fun drone project as you build an altitude control circuit for a popsicle stick drone using an ultrasonic distance sensor and an Arduino™. See this page for a complete list of our mini drone projects. You may wish to do the projects in order. Read more

Dome Sweet Dome

Science Fair Project Idea

Scientific Method

Have you ever seen a geodesic dome? Geodesic domes are approximately sphere-like (or partially sphere-like) structures made up of interconnected triangles. A famous geodesic dome is Spaceship Earth at EPCOT in Walt Disney World, Florida, but geodesic domes are also commonly found as climbing domes at playgrounds. In this science project, you will get to build a geodesic dome using rolled-up newspapers and tape. How much mass do you think your dome will be able to support? Build one and find out! Read more
