thumbnail Do you like getting something for nothing? Everybody likes getting things for free. How about getting energy and power for free? The Sun sends us free energy every second and all we have to do is collect it. Taking advantage of free energy can reduce our dependence on fossil fuels, which are harmful to our environment. In this science fair project, you will work with a solar panel, which is a collector of free energy, and investigate how varying the angle of the solar panel, and thus the amount… Read more

What causes the most stress for teenagers? Is it school? family relationships? peer pressure? worries about the future? Design a survey to find out what contributes to teens' stress levels. Possible variations include: How do teenagers deal with stress? Are today's teens more or less stressed than their parents were as teenagers? Were the sources of stress the same for your parent's generation or different? (Idea from De Biasi, 2003) Read more

thumbnail A ship is a busy place. When out to sea, naval, research, and fishing vessels pull or push heavy loads, like research equipment and crab pots, into and out of the water. But equipment and pots can weigh hundreds of pounds. So how does a ship's crew lift loads efficiently and accurately? With a hydraulic knuckle crane, of course. But what is hydraulics and why does hydraulics make certain tasks easier? Hydraulics is the study of liquids and their mechanical properties: how they move, resist… Read more

The concept of beauty changes over time and often differs among societal groups. How strongly do societal conceptions of beauty shape an individual's self-image? There are many fascinating questions you could choose to explore with surveys on this subject. For example, how well do girls' ideas of what is attractive in boys agree with boys' expectations about what girls find attractive (or vice versa)? Try your survey with different generations to see how conceptions change over time. If you… Read more

Did you know that you can make a simple hygrometer (a device for measuring the relative humidity of the air) with hair? This type of hygrometer is easy to build (for instructions, see: ). Does the type of hair used in the hygrometer affect the accuracy of the results? Do some types of hair respond faster than others? Do some types of hair give a larger (or smaller) response? You could get hair samples from classmates, or a local beauty shop. Use hair samples of equal length to construct… Read more

How does temperature change as barometric pressure changes? You can make a device to test this using a barometer and a thermometer on your stovetop. You can collect your own weather data from a barometer and thermometer over a period of a week or month. You can also use data from a weather station to plot the relationship between barometric pressure and temperature. Does the pressure change as humidity changes? Measure the pressure in a humid and non-humid environment (like your bathroom… Read more

Sunspot activity has been monitored continuously since about 1700. The historical data shows that sunspot activity rises and falls in a roughly 11-year cycle. This project shows you how you can use a spreadsheet program to perform both graphical and statistical analysis to look for patterns in cyclical data. You'll learn how to use a t-test, which is a measure of statistical significance. . Read more

Here's a project idea for all of you bakers out there. What happens if you try your favorite muffin recipe with different types of flour (e.g., white, whole wheat, rye, soy, etc.)? Think of ways you can measure the results. How would you measure the density of a muffin? A kitchen scale would definitely be useful for this project, both for measuring the results and for portioning out the batter for equal-sized muffins. What other measures might be of interest?

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
