Water Drops and Sparks! Experimenting with a Kelvin Electrostatic Generator

Science Fair Project Idea

Scientific Method

Water is an interesting thing. We drink it, swim in it, and wash ourselves with it. We can get energy from water by damming it and sending it through a turbine. But did you know that we can use the natural electrical charges present in water and a Kelvin electrostatic generator to create sparks? You can even use a Kelvin electrostatic generator to temporarily light a bulb! Now that is one bright idea! Read more

Water is one of the most important resources for life. Here on Earth, we often take it for granted — we can easily get a glass of water from the tap whenever we’re thirsty. But imagine being an astronaut orbiting hundreds of miles above our planet. In space, every drop of water is precious, and there’s no tap to turn on. Transporting water from Earth to the ISS is incredibly expensive and impractical due to the limited cargo space and the high cost of launching supplies. To address this,… Read more

Water Striders & Surface Tension

Science Fair Project Idea

Scientific Method

Water striders (also called water bugs, pond skippers, etc.) are insects that can hop around on the surface of water (Figure 1). Unlike boats or other floating objects that are partially submerged and held up by the resulting buoyant force, water striders are held up by surface tension. Figure 1. Water striders (image credit Isaka Yoji). You can build your own water striders using thin wire (Figure 2 and summary video). Do some background research about… Read more

Wearables are found all over the biomedical world: heart rate monitors, EKG patches, braces, etc. In this project, you will make your own wearable air quality sensor that notifies you of high-risk air. You can attach the sensor patch on any existing clothing or even make a standalone patch that you can wear as a necklace or a bracelet. Read more

Sewable circuits are a fun way to mix electronics and arts and crafts by sewing circuits into clothing or fabric. This sewable circuit focuses on creating a unicorn horn with a programmable red-green-blue (RGB) LED in the tip that changes colors. You will use conductive thread to make the circuit, but your stitched lines will also form the spiral lines of the unicorn horn. Read more

Sensors are everywhere—on your phone, in your car, and even at the grocery store. Learn how to craft your own wearable sensor that you can put on your clothing. Using a simple and easy crafting method, you will be able to weave your own capacitive touch sensor patch that will detect when someone touches the fabric. You can use the sensor to turn on an LED, buzzer, or motor when it detects touch! Read more

What Do We Do With Our E-waste?

Science Fair Project Idea

Scientific Method

If you made a pile of all the electronic devices (cell phones, computers, stereos, televisions, MP3 players, video game systems, remote-control toys, etc.) that your family has gotten rid of since you were a baby, how big would that pile be? Would it be taller than you? Would it fit better in a wheelbarrow or in a pickup truck? And did they just throw it in the trash? In this science project, you'll explore what people in your community do with electronic waste, commonly called e-waste, and… Read more

What is the Woolly Mammoth's Closest Living Relative?

Science Fair Project Idea

Scientific Method

Woolly mammoths shook the ground of ice-age tundras for millennia, living next to saber tooth tigers and prehistoric man. Although they have been extinct for thousands of years, scientists continue to learn more and more about this mighty animal. Some of the most exciting new research is being produced by looking at DNA extracted from the hair and bones of woolly mammoths entombed in ice. In this genomics science fair project, you will use bioinformatics tools to determine the woolly mammoth's… Read more

What Sugar And Tea Does a Kombucha Biofilm Prefer?

Science Fair Project Idea

Scientific Method

You may have seen kombucha at the grocery store marketed as a healthy food choice. Did you know this drink is made with a special biofilm that ferments sugar into the tangy, fizzy drink? How does it do that? In this experiment, you'll learn how to make your own kombucha from a biofilm and what tea or sugar substrates you can change! Read more

Where does CO₂ come from and how does excess carbon dioxide in the atmosphere affect the ocean and aquatic life? In this lesson students are introduced to the carbon cycle and explore pH and acidification with hands-on experiments. They then connect their experimental data with real-world data to evaluate claims about carbon dioxide and ocean acidification. Finally, students are introduced to how different companies and research groups are using green chemistry to build carbon capture… Read more
