Science Fair Project Idea

Scientific Method

Carbonated bevarages are quite popular in the United States (despite the health risks of drinking too much of the sugary ones). Many people love their bubbly, fizzy flavors. But how do the bubbles, fizz, and taste get into the water? In this cooking and food science project, you will work with baking soda, citric acid, and sweetener to create a your own soda pop. Once you develop your recipe, try it out on your friends and family. Who knows? You might create the next soda pop sensation! Read more

Racial and Gender Bias in AI-Generated Images

Science Fair Project Idea

Scientific Method

If someone asks you to draw a picture of a doctor, lawyer, or engineer, what first pops into your mind? The race and gender of the person you imagine might be shaped by your personal life experiences, such as whether you have family members in those professions, or what representations of them you have seen on TV or online. What do you think will happen if you ask an artificial intelligence (AI) program to generate the picture instead? Will pictures generated by AI reflect the true real-world… Read more

Build a Simple Steerable Robot

Science Fair Project Idea

Engineering Design Process

Beginner robotics projects like the Art Bot and Bristlebots are fun, but the robots wobble around randomly and cannot steer. If you are ready for a robotics project that is a little more advanced (that does not require any programming), try this one out! You will build your own steerable robot with a wired remote control.

How Acidic Waters Make Rocks Disappear

Science Fair Project Idea

Scientific Method

If you have ever prepared a cup of coffee or tea with sugar, you have probably seen that the grains of sugar quickly dissolve and completely disappear in hot water. But sugar is not the only type of solid that can readily dissolve in a liquid. In fact, there are some types of rocks that can be dissolved by common liquids. It might be hard to imagine large, hard rocks being eaten away by some ordinary fluids, right? But it actually happens all the time! In this geology science project, you will… Read more

Build a Model Planetary Lander with micro:bit

Science Fair Project Idea

Engineering Design Process

How do you make a spacecraft land safely on the Moon or another planet like Mars? It probably helps to know how far away the ground is so you can deploy landing gear, activate a parachute, or fire thrusters to help slow down. In this project you will build your own "lander" vehicle with a sensor that can measure distance to the ground, allowing you to program outputs like blinking lights or an audible alarm. Read more

Where Do Earthworms Hang Out When Food Is Around?

Science Fair Project Idea

Scientific Method

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

Moss is Boss: Using Plants to Determine Direction

Science Fair Project Idea

Scientific Method

Have you ever gone camping, looked up at the stars, and found the Big Dipper? Two stars in the dipper part of this constellation point to Polaris, the north star, which people have used for thousands of years to help them find their way. In this plant biology science fair project, you'll investigate whether plants, like moss, can help you find your way, too. Read more

Measuring Surface Tension of Water with a Penny

Science Fair Project Idea

Scientific Method

Did you know that even though water is a liquid, it isn't always able to get into little cracks and crevices? So how do clothes go from caked with mud to clean? How can dishes go from greasy to glistening? With a few simple household items, you can find out! Read more

What Modern Microbes Could Survive on Early Earth?

Science Fair Project Idea

Scientific Method

Have you ever wondered how life began on Earth? Or how life could get started on other planets? To help us better understand how life began, many scientists try to figure out what it would have been like to live on early Earth. In this science project, you will try to grow microscopic life that could have survived some of the harsh conditions of early Earth! Read more

Shaking for Butter

Science Fair Project Idea

Scientific Method

Hot pancakes with butter running down the sides, freshly baked biscuits and pastries with butter, hot flaky potatoes with melted butter. Yum! It seems like everything tastes better when you add butter. But what is butter and how is it made? In this food science fair project, you will find out, and you will test different conditions for making butter and determine the best method. Read more
