Landscapes and Water Usage

Science Fair Project Idea

Scientific Method

Some plants use a lot of water, and some are very drought-tolerant. Drought-tolerant grasses are good for water conservation because they require less water to grow and stay green. How much less water do they need? Which types of grass are drought-tolerant? You can buy different types or brands of grass seed at your nursery that claim to be drought-tolerant. Grow them in a container and then starve for water after they are established. Which brands die out first? You can conduct a similar… Read more

Puppy Proportions: Comparing Growth Spurts and Weight Gain in Your Dog's Early Months

Science Fair Project Idea

Scientific Method

Planning on getting a new puppy soon? Why not use some of your play time with puppy to study growth rates and puppy development? You can easily chart a young puppy's weekly weight and growth over several months to compare how quickly body dimensions and bone lengths change. While this project may take some time, it's well worth the effort. You might be amazed at the dramatic growth of your "canine kid," and what other project combines science with as much fun, or a more adorable subject? Read more

Earthquakes

Science Fair Project Idea

Scientific Method

Visit the USGS Earthquake Hazards Program to find out about global patterns of earthquake incidents (USGS, 2006). Can mapping earthquakes help identify fault lines? They also have a list of science fair project ideas. Another great resource for earthquake-oriented science fair projects is by Jeffery Barker (Barker, 1994). Build a model to study the forces of an earthquake using sandpaper-covered blocks. What are the forces involved? How are stress and friction in balance along a fault line?… Read more

Want to Warm Up or Cool Down? Go Underground!

Science Fair Project Idea

Scientific Method

Have you ever been so cold sitting in your house in the winter that you feel like icicles could grow off your nose, and your feet could turn into blocks of ice? Or have you ever been so hot in your house in the summer that sweat just drips off you? Making yourself comfortable can mean turning on the heater or the air conditioner, but that costs money. Being cozy or cool does not have to cost a lot of money if you use a geothermal heat pump. In this project, you will build a model geothermal… Read more

Strength of Different Construction Materials

Science Fair Project Idea

Scientific Method

There are many types of construction materials used for wood-frame houses. Compare the different uses for and strengths of different building materials, e.g.: particle board, plywood, pine, oriented strand board (OSB), and drywall (gypsum board, SheetRock). The Science Buddies Materials Science Resource Stress, Strength and Strain will be helpful for learning about different ways to measure material strength. You should be sure to use the same cross-sectional area of each material in order… Read more

Salt Oscillator

Science Fair Project Idea

Scientific Method

Fill a jar a little more than half full with fresh water. Make a solution of salt water, and add a drop or two of food coloring to it. Pour the salt water solution into a plastic cup with a small hole in the bottom, and then place the cup in the jar with fresh water. (The only connection between the fresh and salt water should be via the hole in the bottom of the cup.) With the right combination of hole size and salt concentration, you will see an oscillating current develop in the jar. … Read more

Create Light Up Artwork with a Raspberry Pi

Science Fair Project Idea

Scientific Method

Have you ever seen night lights that automatically turn on when it gets dark? What about art projects, like paintings or sculptures, with embedded lights? This project will let you combine the two, by adding lights to an art project of your choice. You can make the lights automatically turn on when it gets dark using a Raspberry Pi. Check out the video to see what this simple, but fun, project looks like. IMPORTANT: The instructions for this project were originally written using Scratch 2 on a… Read more

Follow the Bouncing Ball: A Web Animation Project

Science Fair Project Idea

Scientific Method

This project is a fun way to try your hand at programming. You'll learn how to create some simple animations, and you'll perform tests and make measurements to help you create more realistic-looking animations. All you need to get started is a Web browser and a text editor (like Notepad). Read more

Speleology: Counting Formations in a Local Cave

Science Fair Project Idea

Scientific Method

Caves have been used for much more than just exploring throughout Earth's history. Caves have been used for shelter, for religious purposes, and for burial sites. They were even used for food storage, before refrigeration, because they are cool and have constant high humidity. But how are caves formed? What causes those fantastic formations in caves? How do cave formations change as you go deeper in the cave? Get ready for an adventure as you visit a local cave and learn more in this science… Read more

How Does Your Eardrum Work?

Science Fair Project Idea

Scientific Method

Eardrums are membranes inside your ears that vibrate when sound waves hit them. These vibrations are converted into electrical signals and sent to your brain, which allows you to hear sound. The frequency response of your eardrum, or the range of frequencies that will cause it to vibrate, determines your hearing range. Typical human hearing ranges from about 20 Hz up to 20,000 Hz, although the ability to hear high frequencies typically degrades as you get older. Some other animals can… Read more
