Day or Night?

Science Fair Project Idea

Scientific Method

Animals have different levels of activity depending upon their habitat, metabolism and behavior. Diurnal animals are more active during the day. Nocturnal animals are more active at night. Being diurnal or nocturnal may have different advantages for different animals. For example, desert animals tend to be nocturnal so they can stay cool and escape the desert heat present during the day. What types of diurnal and nocturnal animals are common in your area? You can set out a small trap to… Read more

Newspaper Tower

Science Fair Project Idea

Scientific Method

Predict how tall you can build a tower using only two sheets of newspaper as building material. You can't use tape, glue, staples, or anything else, just two sheets of newspaper. You can tear, bend, cut, or fold the newspaper. Try it out and see how close you can come to your prediction. Can you beat your prediction? As you're building, you may come up with ideas to make a better tower. Try them out! (It's not like the materials are expensive!) Here are some variations you might want to… Read more

Is It a Country Ballad? Listen to the Beat!

Science Fair Project Idea

Scientific Method

Have you ever noticed that hip-hop songs have a fast tempo, while country ballads are usually slow? Do you think there is a correlation between the number of beats per minute (bpm) in a song and the type of music? You can explore whether different genres of music have different bpm ranges by measuring the bpm in several different songs from a number of different genres. Bpm can be measured using free music software, like the one listed below in the Bibliography, or by counting all the beats you… Read more

Go Wild! Try a Wildcard

Science Fair Project Idea

Scientific Method

Everybody's favorite card in UNO® is the wildcard—why? Because it can stand for any card you want! Your computer uses the same idea. A wildcard on your computer can stand for anything you want when you search. Do this science project to find out if using wildcards to conduct a search can help you find more of what you're looking for. Read more

Stand Up! Investigate the Effect of Different Bowls on Whipped Egg Whites

Science Fair Project Idea

Scientific Method

Whipped egg whites are used in many sweet and savory recipes. They are used to add air into cake batters, meringues, and soufflés. Egg whites, also known as albumin are 15 percent protein dissolved into water. When egg whites are beaten or whipped, the protein chains unravel. This is called denaturation. The process of whipping egg whites adds air to the mixture, in addition to denaturing the proteins. The denatured proteins create bonds with each other and trap air bubbles within… Read more

Time is Money

Science Fair Project Idea

Scientific Method

How many times have you heard from your parents: "Clean up your room!" or "Don't forget to unload the dishwasher!" By applying principles of industrial engineering and time management, you can speed through your chores and have more time to kick back and relax. Read more

CD Burning: Take it to the Edge

Science Fair Project Idea

Scientific Method

Did you know that you can tell how much information is on a CD-R without even using a computer? Find out how in this "reflective" experiment. 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

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

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
