Encryption

Science Fair Project Idea

Scientific Method

Want to send coded messages to your friends? Can you write a simple letter-substitution encryption program in Python or JavaScript? How easy is it to break the simple code? Can you write a second program that "cracks" the letter-substitution code? Investigate other encryption schemes. What types of encryption are least vulnerable to attack? Read more

Testing the Strength of Martian Bricks

Science Fair Project Idea

Scientific Method

For a colony of humans to survive and thrive on Mars, they will need to make the most of what is available on Mars. We know from prior space missions what the Martian ground cover looks like. In this project, you will see if this ground cover can be transformed into strong construction material. The first requirement for construction material is that it is strong so it does not collapse under its own weight. Because the mass of Mars is about 10 times less than the mass of Earth, its… Read more

Barometric Pressure and Weather

Science Fair Project Idea

Scientific Method

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

The Art & Science of Making Yummy Yogurt

Science Fair Project Idea

Scientific Method

Yogurt is a very versatile dairy product. It's yummy eaten straight from the container, it is good for your digestive system, and it can be used in several ways for cooking. There is historical evidence that yogurt-making developed 4,500 years ago! Humans depended on yogurt-making as a way to preserve milk. Yogurt is the result of bacterial fermentation of milk. In fermentation, the bacteria consume the milk sugar, lactose, and produce lactic acid. The end-product is a thick, creamy, and tangy… Read more

Killing 'Vampires': Saving Money and Power by Turning Off Computer Peripherals

Science Fair Project Idea

Scientific Method

What do you think about killing vampires? No, no, not the kind that drink people's blood, but the kind that suck your power and money away. Equipment like televisions, computers, printers, and fax machines all use electricity to operate, of course, but do you realize that this equipment might still be sucking electricity from the wall, even when you think it's turned off? These electricity-suckers are called vampire loads. In this science project, you will investigate how much power these… Read more

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

Skateboard Extremes: Which Wheels are Best for Speed & Turns?

Science Fair Project Idea

Scientific Method

Skateboarder alert: Extreme performance needed in this project. You can cruise and carve while you investigate which skateboard wheels produce the fastest (and slowest) rides on your terrain in these experiments. You pick the wheels and design the tests you think will produce the most extreme results for speed and turns. Do this project and you can work on your ride and learn some science about the speed, spin, and design of skateboard wheels. Read more

When the Sun Rises: The Effect of Light on the Movement of Daphnia

Science Fair Project Idea

Scientific Method

Changes in the environment, or stimuli, affect your behavior and movement over the course of a day: When you get cold, for instance, you might get up and put on a sweater. Or if it is sunny and warm, you might go outside to play sports or go for a walk. Different stimuli, including light, affect the movement of other organisms as well. But how does the type of light influence their movement? Do they respond differently to different kinds of light, depending on other factors in their… Read more

Ocean Currents and Weather

Science Fair Project Idea

Scientific Method

Ocean currents have a huge impact on our weather. If not for the ocean currents, the global climate would be similar to an ice age. Do you live near the coast? Find out which currents are near your coastline. How do they affect your climate? Where do they come from? Do they bring colder or warmer water to your area? Are they seasonal? What do you think your area would be like without them? Every three to seven years there is a weather phenomenon called El Niño, which is caused by… Read more

Talk About a Bad Hair Day!

Science Fair Project Idea

Scientific Method

Did you know that you can make a simple hygrometer (a device for measuring the relative humidity of the air) with hair? Search online for instructions to build one. 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 each hygrometer. To force… Read more
