Science Fair Project Idea
Virtual reality (VR) headsets are becoming increasingly popular. Video game designers use a variety of programs to create the amazing 3D worlds that you see when you turn on your favorite video game, and many of those worlds are now also designed to be compatible with VR headsets. Can you use a computer-aided design (CAD) program or video game engine to design your own virtual world that can be viewed using a VR headset? Did you know you do not have to be a programming expert to create… Read more

Science Fair Project Idea
Your drinking water probably started out brown and muddy. Are you surprised? Maybe you were picturing it flowing from a clean mountain spring instead? All over the world, including in 68% of American homes, people get their drinking water from rivers, lakes, and other surface waters. This water is filled with dirt, debris, and other contaminants as it travels hundreds of miles. So, how does your drinking water go from brown and muddy to crystal clear? Often, flocculants—substances that… Read more

Have you ever wondered how your clothes get their color? Dyeing textiles is a very complicated process and involves a lot of chemistry. Not only are the properties of the dye and fabric important, but the dyeing conditions also have to be exactly right to get optimal color adsorption. Curious about how it works? In this science project, you will color wool with Kool-Aid® and explore the chemistry of dyeing. Read more

Science Fair Project Idea
Do you or your family have a lawn, garden, or potted plants that you water regularly? Irrigation—or the artificial application of water to plants and landscaping—accounts for over two-thirds of the world's freshwater consumption (U.S. Geological Survey, 2016)! While that total includes farms, in the United States landscape irrigation still accounts for almost one-third of residential water use. As much as half of that water is wasted due to inefficient watering methods (WaterSense,… Read more

Science Fair Project Idea
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

Time Required Very Long (1+ months)
Prerequisites Previous experience using a multimeter and being familiar with the physics of electricity is helpful, but not required.
Material Availability The needs to be special-ordered from our partner .
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 or power plugs, or have their fibers dispersed in the air.

Have you ever wondered how virtual reality works? With virtual reality, people feel like they are in one place while knowing they are somewhere else. In this project, you will show the same phenomenon on a smaller scale. You will use the McGurk effect to show how you can hear one sound, while knowing a different sound is physically there. First, you will produce such an experience using audio and video, and then measure the strength of the phenomenon. Read more

Have you ever been told to avoid certain foods because they contain too much fat? Almost every food we eat has some amount of fat in it; often in an invisible form so we do not even notice. However, eating healthy does not mean getting rid of all fat in your diet. On the contrary, fat is an essential nutrient for your body! Only consuming too much of certain fat types creates problems. Are you curious about how to determine the fat content of different foods? Gather some chips, chocolate, and… Read more

Safety Acetone is a flammable liquid. Keep away from open flames, sparks, or heat. Acetone is irritating to skin and eyes. Be sure to wear safety goggles and gloves. Work in an area with adequate ventilation. Adult supervision is recommended. Do NOT eat the foods that you treated with acetone.
Science Fair Project Idea
Have you ever tried an apple that tastes like a banana? It sounds weird, but what actually makes the apple taste like an apple? Our tongue is definitely important for identifying food flavors, but if you have ever had a stuffy nose, you probably noticed that your smell contributes to taste as well. Which of those senses has more influence on flavor? Imagine eating an apple and, at the same time, smelling a really strong banana scent. How to you think the apple will taste? Will the nose or the… Read more

Earthworms are important for the soil and fun to study. In this science project, you will find where earthworms like to stay when food is around. Will they gather around the food, take food with them in their tunnels, or not be attracted to the food at all? You will fill four pots with dirt, add food and worms, and track their activity over one week to find out! Read more

Drones—also called quadcopters or unmanned aerial vehicles (UAVs)—are an increasingly popular toy for hobbyists. Some companies even want to use them for business purposes, like delivering packages right to your doorstep! However, drones typically have a rather short battery life. Does the added weight of a package affect a drone's battery life? Try this project to find out! Read more
