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 Direct Reprogramming Can Transform One Type of Cell Straight into Another

Science Fair Project Idea

Scientific Method

In the first decade of the 21st century, scientists found ways to make one adult cell type turn into a completely different cell type. This has huge implications for the medical field, including being able to take some cells that a person could spare, such as skin cells or blood cells, and turn them into another cell type that might be much more important for that person to have, such as cells to make a new kidney. How are scientists able to accomplish this amazing feat of "reprogramming" the… Read more

How Do You Get Heat from a Supercooled Solution? Explore the Chemistry Within Hand Warmers

Science Fair Project Idea

Scientific Method

You're at the high school football game and it's getting pretty chilly as the sun goes down. You're determined to keep cheering for your team, but your hands are freezing—have you ever tried hand warmers? The chemistry within these little packets is pretty cool. Hand warmers provide a unique and fun way to study the chemistry of crystal formation and heat generation. By pressing a button in a pouch, which contains a supercooled solution, you start a rapid exothermic (heat-producing)… Read more

How Do You Know Where You Are Without GPS? Dead Reckoning and Inertial Navigation

Science Fair Project Idea

Engineering Design Process

Put a meter stick on the ground. Starting at one end of the stick, close your eyes and try to walk exactly one meter. Open your eyes. How close were you? Now try it again with five, ten, or twenty meters. Does it get harder as the distance gets bigger? Without an outside reference from your visual system, it's quite difficult to know exactly how far you've gone! Electronic navigation systems face the same problem. Without an external reference like the global positioning system (GPS), it's very… Read more

How Electricity Changes pH in Salt Solutions

Science Fair Project Idea

Scientific Method

You have probably heard the saying that "water and electricity don't mix." Well, in this chemistry science fair project you will mix them, to create two solutions, one basic and one acidic. The apparatus is very simple, but the chemistry is complex and offers many avenues for exploration. Read more

How Fast is Automatic Braking?

Science Fair Project Idea

Scientific Method

How fast can a human driver react and hit the brakes when there is an obstacle in the road? Can autonomous cars react more quickly and make the road safer for everyone? In this project you will build your own Arduino robot and test human braking versus automatic braking as the robot drives toward an obstacle at full speed. Read more

How Long Does It Take to Fry a Diode?

Science Fair Project Idea

Scientific Method

If you have ever built an electronic circuit with a soldering iron, you know that the component leads get hot. How much of that heat gets into the device you're soldering? This project shows you how you can use a silicon diode as a temperature sensor to find out. 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

Investigate Native Plant Evolution with Chloroplast Sequencing

Science Fair Project Idea

Scientific Method

Native plants are important for both ecological and medicinal reasons. However, most native plants are not very well studied. One way to know more about these plants is to understand which other species of plants they are most closely related to. In this science project you will sequence part of the chloroplast genome from a native plant and use this information to determine its evolutionary relationship to other species of plants. If the plant you chose has not been sequenced before, you can… Read more

Ion Thruster: Build an Ion Wind Rotor

Science Fair Project Idea

Scientific Method

Ion thrusters, also called ion engines (Figure 1), are a type of electrically-powered spacecraft propulsion. While they provide very low thrusts (and thus low accelerations), they can do so for very long periods of time using a very small amount of fuel. So, while not appropriate for escaping Earth's gravity like chemical rockets which are less efficient but generate higher thrusts, they are useful for deep-space probes or making small adjustments to satellite orbits. You can read more about… Read more
