The Physics of Cheating in Baseball

Science Fair Project Idea

Scientific Method

Do corked bats really hit the ball further? What about other materials? Here's a project to find out. Read more

Tracking SARS-CoV-2 Spread from Wastewater

Science Fair Project Idea

Scientific Method

Have you ever wanted to know where hot spots of infection are or see how viruses spread? Are you interested in seeing how this changes over time? Check out our new science project that uses data visualization tools and tested wastewater data to track the virus that causes COVID-19 over time. Read more

Understanding Lactose Intolerance

Science Fair Project Idea

Scientific Method

What do pizza, milk shakes, and ice cream sundaes have in common, besides being delicious and loaded with calories? You might be surprised to learn that these foods, because they contain dairy products, cannot be eaten by the majority of people around the world. Dairy products contain the sugar molecule lactose, and the majority of people on the planet slowly begin to lose the ability to digest lactose after the age of 2. In this human biology and health science fair project, you will… Read more

Which Is the Better Insulation Material?

Science Fair Project Idea

Scientific Method

You've probably noticed that the price of gasoline has been going up and up lately. Heating oil will probably cost more this winter than last winter, too. Using good insulation material is one way to conserve energy and save money. What insulation materials work better than others? Read more

A Juicy Project: Extracting Apple Juice with Pectinase

Science Fair Project Idea

Scientific Method

Do you know why enzymes are oftentimes called the workhorses of biochemistry? It's because they can speed up a wide variety of chemical reactions, and chemists and biologists use enzymes to do all kinds of jobs. In this project, pectinase, an enzyme frequently used in the food industry, will be used to extract juice from apples. Read more

A Model of Gravity in Our Solar System

Science Fair Project Idea

Scientific Method

Why do the planets orbit the sun without flying off into space? Do they move in perfect circles or do their orbits take a different shape? And how could you possibly do a science project about any of this—you can't do an experiment with the planets! However, you can build a model of our solar system that demonstrates the concept of gravity, using balls of different sizes to represent the sun and planets. Watch the summary video for an excellent introduction to the model. Think about how… Read more

Build a Light-Tracking Bristlebot

Science Fair Project Idea

Scientific Method

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

How much energy does a roller coaster need to go through a loop without getting stuck? Build your own marble roller coaster in this project and find out! Read more

Build a Speedy Light-Tracking Robot (BlueBot Project #2)

Science Fair Project Idea

Engineering Design Process

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

If you have ever watched a rocket launch on TV, you might have noticed that rockets have multiple stages. Some parts of the rocket fall off and burn up in the atmosphere whereas the rest of the rocket keeps going. Why does this happen? Try this activity to find out and build your own two-stage rocket using balloons! Read more
