How many ball sports can you name? How many of those have several balls at once in the game? Almost none, right? Games that do use several balls at a time most likely use balls of the same mass, volume, and material. Would having two balls of a different mass make a game very difficult? In this activity, you will explore what might happen if you were to add a tennis ball to a basketball game, or a tiny ping pong ball to a tennis game, or any other combination. Ready to be surprised? Try it out! Read more

Energy Is Blowing in the Wind

Science Fair Project Idea

Scientific Method

Have you ever watched how trees sway and bend in a strong wind? Have you ever thought about all the homes that could be powered with forces from the wind? In this project you'll discover, through trees, good places in your community for generating wind power. Read more

Enjoy It Now... Or Enjoy It Later? Understanding Delayed Gratification

Science Fair Project Idea

Scientific Method

Have you ever thought to yourself, "I have got to have that new video game right now?" Or maybe there's a new shirt at the store that you just have to have. So you rush home, break into your bank, and gather all of your money, even though you have been saving to buy your mom a gift. But wait! Maybe if you do a few more chores and save for just a few more days, you can gather enough money to buy your mom a gift and buy what you want. This behavior is called delayed gratification and it's what… Read more

Estimation and Population Size

Science Fair Project Idea

Scientific Method

Have you ever wanted to take a short cut? How about when doing your math homework? In this experiment you can learn how estimation can save you time doing math calculations. But beware, some estimations are better than others! Can you match this sample size with the best population? How accurate are your estimation skills? Read more

Evolution of Friendship Groups Over Time

Science Fair Project Idea

Scientific Method

This project asks the question "How do friendship groups change over time?" The results may support inferences about how "people skills" develop. What types of changes would you expect to see? Do you expect friendship groups to grow larger over time? Do you expect that individuals will belong to more, less or about the same number of friendship groups as they get older? Do you think there will be more or less exclusivity among groups (and how would you measure such a concept)? Do you… Read more

Expanding and Contracting Gases: Weekly Science Activity

Blog Post

In this week's spotlight: a chemistry family science experiment that guides students and families in an exploration of how gases behave, especially when they are cooled or heated. Many gases are invisible, but they are everywhere around us. By trapping gas in a balloon, you can investigate how the kinetic energy of a gas changes in response to temperature and how the change in the motion of the gas molecules makes the balloon shrink or expand. With some hands-on measurements, a bit of air… Read more

Experiment with Factors that Affect Roundup® Weed Killer

Science Fair Project Idea

Scientific Method

Farmers are constantly battling various types of weeds that compete with the crops they are trying to grow. One of the tools they use to combat unwanted plants is a chemical called glyphosate. Glyphosate is the active ingredient in Roundup, a widely used weed killer. In this plant biology science fair project, you will explore the factors that affect the activity of glyphosate. Read more

Explore Diabetes with Student STEM Projects

Blog Post

November is National Diabetes Awareness Month. Students interested in science related to diabetes can learn more with hands-on science projects and activities. Exploring Science Questions Related to Diabetes When faced with a science project or science fair project assignment, students who have Type 1 Diabetes, or have a family member of friend with diabetes, often immediately think about exploring a science question related to diabetes. Diabetes… Read more

Explore Magnification with a Drop of Water: Weekly Science Spotlight

Blog Post

What happens when you look through water at something below it? Does the object (or image) appear larger? Does it appear smaller? How much larger or smaller? It may depend on the shape of the water. Viewing something through a drop of water may make the object or image appear larger. Viewing through a layer of water in a container like a cup, on the other hand, may have a different effect because the curvature of the water is different. (The size of the drop of water may also make a… Read more

Explore Radioactive Decay with Coins

Blog Post

Explore the science of radioactive decay with a safe hands-on family STEM activity. As radioactive materials decay, or break down, they emit radiation that may be harmful. Unfortunately, the amount of time it takes for a radioactive material to decay varies. Scientists talk about the rate of decay in terms of the material's "half-life." Some materials have a very short half-life and others have a very long half-life. In this week's family science activity, students can simulate… Read more
