Have you ever played a game at a carnival, trying to win a stuffed animal or other prize? It might look easy, until you try it. Why are those "simple" games at the fairs and carnivals so hard? Is it really lack of skill or coordination or do those concessionaires use some basic laws of science to help them set up the games in their favor? In this science activity, you will investigate how physics can help you win — or lose — at the classic game of trying to knock over a pyramid of… Read more

Think Like a Computer: Try Machine Learning

Science Fair Project Idea

Engineering Design Process

What should you eat for breakfast today? What should you wear to school? You make many decisions every day and consider lots of information when making those decisions. What if you could train a computer to make those decisions for you using artificial intelligence? In this project, you will not need to do any computer programming yourself, but you will do some simple math to show how a computer program called a neural network can learn to make decisions. If you want to try a version of the… Read more

Are you ready to bend light, magnify letters, and have fun with drops of water—all while getting a glimpse into how lenses work? Lenses are the key components in eyeglasses, contact lenses, binoculars, telescopes, and magnifying glasses, just to name a few devices. With this activity, a homemade magnifying glass is only a drop away! Read more

Have you ever wondered why salt is used to de-ice roads? Did you know that snow sticks more readily to pavement that has been treated with salt? Why would this be the case? In this activity, you will use the same principles to hoist ice cubes with a piece of string. Is it possible to do this without getting your hands cold? Try the activity and see what a pinch of salt can do! Read more

Use the Sun's Energy to Heat Your Own Water

Science Fair Project Idea

Scientific Method

Isn't it nice to take a nice, hot shower or bath after a long day of playing outside? But have you really thought about how the hot water in your shower or bath gets hot? Sure, the water heater in your house gets it hot, but what makes the water heater work? Water heaters are powered by natural gas or electricity. But are there any other ways to heat water? What about using the Sun? In this science fair project, you'll give it a try by capturing energy from the Sun to heat water. Read more

Have you ever walked across a large parking lot on a sunny day and felt like you were roasting? That's because the asphalt gets really hot in the sun! Streets, buildings, and parking lots can get so hot that they raise the average temperature of urban areas by a few degrees. Do you think natural materials also heat up in the sun, or only man-made materials? Do this activity to find out! Read more

Water from Air: Experimenting with Dew Traps

Science Fair Project Idea

Scientific Method

Most of us live in areas where sources of water exist nearby as oceans, rivers, lakes, ponds, streams, reservoirs, wells, or even underground streams. But in some places, like the desert, water is hard to find and a precious resource. In this environmental engineering science project, you will investigate one way that people living in arid regions can collect water inexpensively: dew traps. Read more

Water Striders: Survival Adaptations

Lesson Plan Grade: 3rd

How do water striders skip across the surface of the water? What advantage does this give them over other insects that helps them survive in their environment? Your students will find out in this lesson as they build their own insects from pieces of wire, and see which ones sink and which ones float. Read more

NGSS Performance Expectations:

3-LS4-3. Construct an argument with evidence that in a particular habitat some organisms can survive well, some survive less well, and some cannot survive at all.

Have you ever heard anyone say the chance of something happening is "50-50"? What does that actually mean? This phrase has something to do with probability. Probability tells you how likely it is that an event will occur. This means that for certain events you can actually calculate how likely it is that they will happen. In this activity, you will do these calculations and then test if your calculations hold true for reality! Read more

What Do Enzymes in Pineapple Juice Do to Milk?

Lesson Plan Grade: 5th

In this fun chemistry lesson, students will explore chemical reactions by mixing pineapple juice and milk. Students will observe whether the properties of milk change when it is mixed with pineapple juice, as well as how they change. They will then infer from their results whether a chemical reaction happened. In the process, they will not only learn about chemical reactions but also discover the importance of enzymes and their role in the human body. Read more

NGSS Performance Expectations:

5-PS1-4. Conduct an investigation to determine whether the mixing of two or more substances results in new substances.
