Counting Sunspots on an Image of the Sun

Science Fair Project Idea

Scientific Method

Make a pinhole projector (see Measuring the Diameter of the Sun and the Moon). Use the pinhole to project an image of the Sun onto a wall or a piece of paper. Do you notice any dark spots on the projected image? Trace the projected image and count the dark spots. Use your pinhole projector to make images of the Sun at the same time of day for several consecutive days. How does the pattern of spots change? Can you use your data to figure out how fast the Sun rotates? Sunspot activity rises… Read more

Printing Power! Save the Environment, One Printer Page at a Time

Science Fair Project Idea

Scientific Method

Do your parents ever get upset with you for "wasting" paper and ink from your printer? Maybe you wanted to print a comic you found online, or a whole bunch of pictures of you and your friends being goofy, or all the instructions on how to put together that really awesome LEGO® castle. But 20 pages of text and pictures later, your mom or dad is yelling at you. Why do they even care how much you print? And why do people say it is a "waste" of paper? Try this printer-saving science project to… 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

Does Virtual Practice Make Perfect?

Science Fair Project Idea

Scientific Method

You've probably heard the phrase, "practice makes perfect" more times than you care to remember, but is it actually true when you use a music game as your practice for real-life singing, strumming, or drumming? You can design a science fair project to discover the answer! First, you'll need to think about how to measure how well someone is playing or singing a song in real life. Using the test you design, measure several musicians' ability to play or sing a few different songs. Then have your… Read more

Frequency of Outcomes in a Small Number of Trials

Science Fair Project Idea

Scientific Method

People often draw conclusions from a small number of observations, and use those conclusions to evaluate the likelihood that an event will take place. But how easy is it to draw the wrong conclusion based on those observations? Will your predictions be accurate if an experiment is only performed a few times? The objective of this project is to determine what happens when a test with two equally-likely outcomes is performed only a small number of times. You can test this by flipping a coin. A… Read more

Macro for Micro?

Science Fair Project Idea

Scientific Method

If the prefix "macro" means large and "micro" means small, then why will the macro setting of a digital camera help take a better picture of a small object? Do this experiment and get the big picture. Read more

Need Help Getting Out of a Sticky Situation?

Science Fair Project Idea

Scientific Method

Does adhesive tape hang tight at different temperatures? Measure the adhesive strength of tape at both low and high temperatures. To raise the temperature, we suggest using a blow dryer at both low and high heat settings. To lower the temperature, use an ice pack (try to keep condensation from forming on the tape and confounding the results). For even lower temperatures you could try "dry ice" (frozen carbon dioxide), if available. (Wear heavy gloves when handling dry ice, because it can… Read more

Measuring Up

Science Fair Project Idea

Scientific Method

Measurements are very important for scientists. It is especially important that the measurements be accurate. Think about how important accuracy is when you want to know if you are taller than a friend of yours, every inch counts! In this experiment, you will investigate how different objects can be measured with accuracy. Are small or large objects more difficult to measure? Who in your family is the best at measuring? Maybe it will be you! Read more

Temperature, Weather, and Air Movement

Science Fair Project Idea

Scientific Method

What are cold fronts and warm fronts? What happens when a cold front meets a warm front? You can test this using different temperatures of water. Use food coloring to label the cold and hot water, then carefully combine the two liquids together. What happens? How do they mix? You can also fill water balloons with hot or cold water, and then float in a hot or cold water bath. How does temperature affect the movements of the balloon? You can do similar experiments with hot and cold air in… Read more

Plastic Deformation: Glass Transition of Some Plastics

Science Fair Project Idea

Scientific Method

Some plastics undergo an unusual transition, from a hard, glassy state to a soft, rubbery state, with increased temperature. For this project, you should do background research on the effects of temperature on different types of plastics. Make sure that you understand the difference between thermosetting and thermoplastic polymers. You should also look for information on the glass transition temperature (Tg) for different plastics. Pure polyvinyl acetate has a Tg of 28 C (about… Read more
