Science Fair Project Idea
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 build an electronic device that measures the light given off by luminescent materials. The device will be used to study how temperature affects luminescence. Read more

Time Required Long (2-4 weeks)
Prerequisites A familiarity with basic chemistry is required. Also, some experience with electronics would be helpful. Although the circuit is fairly straightforward, especially if you use the kit, this is a DIY ("do-it-yourself") project that will call for some creative problem solving on your part.
Material Availability Any phosphorescent material will work for this project. If you want to use super-bright phosphorescent paints, they are available online. See the Materials & Equipment list for more information.
Cost High ($100 - $150)
Safety Use caution when using the drill or knife. Wear safety goggles when using the drill.
Science Fair Project Idea
Have you ever seen a cat chase a laser pointer or a flashlight beam? What if you could make a robot do that? In this project, you will build a robot that can automatically drive toward a bright light source. The robot uses a simple electronic circuit to track light, so there is no computer programming required! You can also do three other robotics projects using the same kit of parts, so this is a great way to get started with robotics before moving on to more advanced projects. Read more

Science Fair Project Idea
Do you read the list of ingredients in foods and drinks before you buy them at the grocery store? If you do, you may have noticed that many of the items that are blue in color have the same dye, called FD&C blue 1. In this chemistry science fair project, you will build a simple colorimeter, a device that measures the concentration of colored chemicals in solutions. You will use the colorimeter to measure the concentration of blue dye #1 in sports drinks, and to track the rate at which the… Read more

Science Fair Project Idea
Do you hate shots? Do you complain about paper cuts? Imagine if you had to give yourself shots a couple of times a day, as well as prick your finger, on purpose, even more frequently. Of course, if you have diabetes you do not have to imagine this; it is your reality. People who have diabetes usually need to keep close track of how much sugar is in their blood (called their blood glucose levels) by testing a drop of blood from a finger prick. If there is too much sugar in their blood, some… Read more

Time Required Average (6-10 days)
Prerequisites Some familiarity with electronic circuits and using breadboards would be helpful, though it is not required for this project. Completion of a basic chemistry class is also recommended before trying this project.
Material Availability A pump and other electronics parts must be specially ordered to do this project. See the Materials list for details. Estimated project time includes shipping of specialty components.
Cost Average ($40 - $80)
Safety Some parts of the circuit can get warm during normal operation. Do not leave the circuit operating when unattended. Be very careful with your wiring to prevent short circuits from happening; short circuits can get very hot and cause plastic parts of the circuit to melt.
Science Fair Project Idea
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

If you want to get your friend's attention at a crowded sporting event with lots of people cheering, you need to shout. If you're trying to do the same thing in a quiet library, a whisper works. The detection limit for each of our senses depends on the amount of "background" stimulation that is already present. This project uses an LED control circuit to investigate detection of changes in light levels. Read more

Science Fair Project Idea
Do you know how to find the north and the south poles of a magnet? What materials are more magnetic than others? Is there a way to measure how strong a magnet is? Is there a way to measure the strength of an electromagnet? How much does the material that is in the core of the electromagnet affect its magnetic strength? With this project, you'll be able to answer these questions and many others. You will learn how to build and use a simple meter for measuring magnetic field intensity. Read more

Science Fair Project Idea
Global warming, climate change, melting ice caps—these are all big events that have an impact our environment. What can we do to help reduce the impact? We can reduce, reuse, and recycle. What can cities do to help? Cities can eliminate waste by saving energy. Cities around the world are switching from incandescent traffic signals to LED traffic signals to save energy and money. That's because LEDs are more efficient than incandescent lamps, which means that LEDs produce more light… Read more
