Science Fair Project Idea
The makers of sports drinks spend tens to hundreds of millions of dollars advertising their products each year. Among the benefits often featured in these ads are the beverages' high level of electrolytes, which your body loses as you sweat. In this science project, you will compare the amount of electrolytes in a sports drink with those in orange juice to find out which has more electrolytes to replenish the ones you lose as you work out or play sports. When you are finished, you might even… Read more

Science Fair Project Idea
Generating power from mud sounds like science fiction, but it is actually real science, and a promising source of alternative energy. Topsoil is packed with bacteria that generate electricity when placed in a microbial fuel cell. Because such bacteria-laden soil is found almost everywhere on Earth, microbial fuel cells can make clean, renewable electricity nearly anyplace around the globe. They are an up-and-coming technology that scientists and engineers are working to make even more… Read more

Time Required Very Long (1+ months)
Prerequisites We recommended that you have a basic knowledge in physics of electricity and familiarity with the concepts of conductivity, electric current, resistance and electrical power. Having used a multimeter before is helpful, but not required.
Material Availability The microbial fuel cell kit needs to be special-ordered from the
Cost Average ($50 - $100)
Safety Be sure to wear the gloves supplied with the kit when handling the microbial fuel cell's electrodes (its cathode and anode). The electrodes are made of a conductive material called graphite fiber and should not be placed near electronics, power plugs, or have their fibers dispersed in the air. The fibers will cause electrical shortages when in contact with electronics.

Imagine telling your friends about your latest science project: using a battery to make a light turn on. You might get some blank stares...sounds a little boring and basic, right? Now tell them you will do it with a potato! Yes, you can actually turn fruits and vegetables into electric power sources! Batteries power many things around you, including cell phones, wireless video game controllers, and smoke detectors. In this science project, you will learn about the basics of battery science and… 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.

What do you do with your old wooden pencils when they get too short to hold? Don't throw them away; you can use them to make circuits! This project will show you how to use pencils to make resistors, an important part of many electrical circuits, and test how they affect the brightness of a lightbulb in a simple circuit. 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

Material Availability Specialty items (see Materials list)
Cost High ($100 - $150)
Safety Since this science project deals with electricity, adult supervision is recommended. The LEDs used in this project are used in traffic signals and are very bright. Do not look directly at the LED when it is in operation and be sure to wear your sunglasses. Be sure to wear safety goggles when operating power tools.
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

What can you do with a bucket of soil? You could use it to grow some beautiful plants and vegetables—or you could use it to produce electricity! Surprised about that? You actually can power electric devices with just mud! Are you curious about how this works? You need some little helpers in the soil—bacteria—that are able to turn their food sources within the soil into electricity in a device called a microbial fuel cell. But is this possible with any soil and does the soil… Read more

Solar cells are popping up on rooftops everywhere these days and are a model for clean, renewable energy. Did you ever look at those solar panels and wonder how we can get electricity produced by solar cells when the sun is not shining? It is a great question because solar panels do not produce electricity when it is dark outside. One strategy to overcome this challenge is to store the energy produced by solar cells during the day in the form of a fuel that can be used at a later time. In… Read more

Dimmer switches let us control the brightness of a light, anywhere from completely off to full brightness. This can be nice when you want to set the brightness "just right," as opposed to a regular light switch that only lets you turn a light on or off. It turns out that you can make a dimmer switch out of an everyday object—a pencil! Try this project to find out how a dimmer switch can control the brightness of a light. Read more
