Flippy, the Dancing Robot

Science Fair Project Idea

Scientific Method

Have you ever seen a robot dance? In this project you will build your own simple flipping, tumbling robot that can dance around on the floor or a tabletop! If you have never made a robot before and would like to get started with a fun, easy project, this is a great place to begin. You will follow directions to make a basic robot, and then make your own additions to make it even better! Read more

Did you know that there are more planets than stars in our galaxy? All of these planets circle around a star, but only eight of them—Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune—circle around the Sun—the star in our solar system. This activity explores the relative size of these eight planets. Is one bigger than the others, or are they all about the same size? Read more

How Bright Is Your Glow Stick? Measure It!

Science Fair Project Idea

Scientific Method

Objects that glow in the dark hold a special place in the imagination of both children and adults. The lights go out at night, but these odd things refuse to disappear. Where does the light come from? Do they work in any climate? In this science fair project, you will make a very simple electronic device to measure the light given off by luminescent materials. The device will be used to study how temperature affects luminescence. Read more

How Does the Intensity of Light Change with Distance?

Science Fair Project Idea

Scientific Method

How does the intensity of a light source change as you move away from it? This project describes a method to verify the inverse square law: how light, sound, electrical signals, and gravity each decrease with distance from their source. It does not matter if you are talking about a lightbulb or the sun; this law still applies! Read more

How Fast Does an Alka-Seltzer® Tablet Make Gas?

Science Fair Project Idea

Scientific Method

This is a straightforward, fun project to measure the rate of the chemical reaction that occurs when Alka-Seltzer® tablets are plopped into water. You will track the volume of carbon dioxide gas produced at regular intervals after the reaction begins. How does changing the temperature of the water affect the production of gas? Read more

How to Control a DIY Mini Drone with an Arduino™

Science Fair Project Idea

Engineering Design Process

Most drones fly with a mix of human input and autonomous control based on feedback from electronic sensors. This allows the drone to fly up and down when the human operator presses a joystick on a controller, but automatically hover at a fixed distance above the ground when the operator lets go of the joystick. In this project, you will explore drone programming with an Arduino. What types of inputs and sensors can you make your drone respond to? What behaviors and responses can you program… Read more

Jumping For Geodes: Can You Tell the Inside from the Outside?

Science Fair Project Idea

Scientific Method

Have you ever heard the expression, "You can't judge a book by its cover"? What do you think that means? That a book with a very plain cover might have a very exciting and interesting story inside? Well, in this geology science project, you'll see if the same expression holds true for a rock, but not just any old rock, a special type of rock called a geode, which looks rather plain and ordinary on the outside, but inside can hold crystals and beautiful colors! You'll discover if the texture or… Read more

Kimchi Chemistry

Science Fair Project Idea

Scientific Method

You're probably familiar with sauerkraut, a German dish of cabbage that is fermented in a brine made of its own juice and salt. Have you heard of another cabbage dish, called kimchi? Kimchi is a traditional fermented cabbage dish from Korea. Koreans eat kimchi year round, enjoying its spicy taste and the fact that it contains loads of vitamins B and C. In this cooking and food science fair project, you will make kimchi from scratch and investigate changes in pH and glucose as the kimchi… Read more

Make a Magnetic Slime Robot

Science Fair Project Idea

Engineering Design Process

Could you use a magnetic slime "robot" to retrieve a battery accidentally swallowed by a small child? Scientists think so! Watch this video to learn about magnetic slime that, when driven by external magnetic fields, can squeeze through small spaces and even grasp objects. Can you make your own magnetic slime robot that can accomplish some of the same tasks demonstrated by the researchers? You can start by adding iron filings to slime to make your own magnetic slime (see this Science Buddies… Read more

Make a Model Rocket Land Vertically

Science Fair Project Idea

Engineering Design Process

Companies like SpaceX and Blue Origin are dramatically lowering the cost of space flight by designing reusable rocket boosters that land back on Earth. Getting a rocket to land vertically without any damage - and without using a parachute to slow it down - is quite a tricky physics problem! In this project you will modify your own model rocket so it can land vertically. Read more
