Racing Drones: Does Practice Make You Faster?

Science Fair Project Idea

Scientific Method

Have you ever flown a drone? Did you find it easy the first time you tried? In this project, you will fly a drone through an obstacle course and measure how practice changes your performance. Will practice help you finish the course in less time? Try it out! Read more

Racing Marbles to Measure Viscosity

Blog Post

Have you ever noticed that some liquids are more difficult than others to squeeze from a container? Honey is a great example. Depending on its temperature, it may be especially slow to flow from the bottle. (If you warm it up, it may flow more quickly!) While it may seem like the quality of the honey you are noticing is its "thickness" or "thinness," another way to talk about what you are seeing is to talk about its viscosity. In this week's chemistry-themed family science… Read more

Racing to Win That Checkered Flag: How Do Gases Help?

Science Fair Project Idea

Scientific Method

Watching professional racing-car drivers compete can be thrilling. The high speeds that racing cars can reach — up to 200 miles per hour (mph) and more! — put some unique demands on the vehicles. For example, to withstand high temperatures, the tires must be inflated with nitrogen gas, instead of air as with normal car tires. This enables the drivers to have better control over steering their cars as they race around the track. In this sports science project, you will inflate… Read more

Recording on a Wire

Science Fair Project Idea

Scientific Method

Today magnetic recording is used in audio and video cassette recorders, and computer disk drives. Did you know that you can also use an electromagnet to record and play back from a steel wire? In fact, this is how magnetic recording got started. This project shows you how to build a simple wire recorder. Read more

Red Eye

Science Fair Project Idea

Scientific Method

How does the angle between the lens, the subject's eye, and the flash effect the appearance of red eye? How does the subject's eye color effect red eye? Read more

Relationships Between Variables: Using Correlation and Linear Regression

Science Fair Project Idea

Scientific Method

Here's a project that combines sports and math. You'll learn how to use correlation analysis to choose the best team batting statistic for predicting run-scoring ability (Albert, 2003). You'll also learn how to use a spreadsheet to measure correlations between two variables. The project description Which Team Batting Statistic Predicts Run Production Best? provides the details.

Remodeling and Energy Efficiency

Science Fair Project Idea

Scientific Method

Has your house (or one of your friend's houses) been remodeled recently? Were any improvements made for energy efficiency (solar systems, better insulation, passive solar heating, better lighting)? Compare your family's energy costs for a similar time period before and after the remodeling (remember that energy usage often varies seasonally). Monthly bills often have a bar graph showing energy usage for the previous 12 months. You may also be able to get information on past energy usage… Read more

Renewable Energy Resources

Science Fair Project Idea

Scientific Method

Coal, gas, and oil are energy resources that are not renewable, meaning that once we use up the world's supply of these natural resources there will not be any left. There is a lot of debate about how long these resources will last. One way to ensure that we will not find ourselves in an energy crisis is to develop energy resources that are renewable. Renewable energy is a resource that cannot be used up. Investigate the many uses of renewable energy: solar energy, wind energy,… Read more

Respiration and Gills: What Factors Affect Respiration in an Aquatic Environment?

Science Fair Project Idea

Scientific Method

During metabolism, organisms experience physical and chemical changes. All animals need some way to exchange chemical waste generated during metabolism for fresh nutrients. One way that these metabolic chemicals are exchanged is during respiration, the process by which used carbon dioxide gas is exchanged with fresh oxygen and circulated throughout the body. How do organisms living underwater respirate? They use gills, which filter oxygen from the water and pass the oxygen into the… Read more
