Have you heard that garlic powder is supposed to inhibit the growth of bacteria? Which do you think would make a better disinfectant: a solution of garlic powder or a solution of bleach? This project shows you a straightforward way to compare the effectiveness of different disinfectants (or other antimicrobial agents), by measuring zones of inhibition on a culture plate.

How can seawater from the oceans be turned into fresh water that is suitable for people to drink? Through a process called solar desalination! In this science project, you will make a solar desalination apparatus using readily available materials, and a power source that is free. How much water can the device produce, and is it still salty at all? What factors affect how effectively saltwater is turned into fresh water?

Have you ever noticed that on a hot day, it's more comfortable to wear a light-colored shirt than a dark one? Or that it's cooler in a park than walking down a street? This happens because different surfaces absorb and reflect heat in different ways. Urban heat islands are parts of cities where man-made surfaces like pavement and buildings replace natural surfaces like grass and trees. In this project, you will use temperature and satellite data to see if certain areas in a city have higher…

Isn't it nice to take a nice, hot shower or bath after a long day of playing outside? But have you really thought about how the hot water in your shower or bath gets hot? Sure, the water heater in your house gets it hot, but what makes the water heater work? Water heaters are powered by natural gas or electricity. But are there any other ways to heat water? What about using the Sun? In this science fair project, you'll give it a try by capturing energy from the Sun to heat water.

Remembering to take medicine at the right time can be hard, especially if you need to take multiple medications at different times of day. It might not be a big deal if you forget to take your daily multivitamin, but for some people, forgetting to take medication at the right time can be dangerous. What if you had a device that could not only set off an alarm at the right time, but also automatically dispense the right pills for you? In this project, you will build an automatic medicine…

Did you know that the color of your house could save money? Do this experiment to see which colors regulate temperature best in different environments. Then convince your parents to paint the house and save some money on their energy bill. Maybe they will be so happy they will also increase your allowance!

What do humans need to survive? We need food, water, and warm shelter. We all need a warm place to live, particularly when it's chilly outside. How do many of us warm our houses or apartments? We depend on fossil fuels to supply gas and electricity to our heaters. But burning fossil fuels to create energy is harmful to the environment. What if there was a way to warm our homes without burning fossil fuels and it was free? In this science fair project, you will build a solar air heater and see…

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…

"How do you frighten a grasshopper? And what does that have to do with light?" These are a couple of questions you're probably asking yourself after reading the title. Well, The Frightened Grasshopper Solar-Powered Bug is actually a toy grasshopper that vibrates when it is placed in sunlight or near a lightbulb. It stores up the energy from light, and converts it into motion. You will use this fun toy to explore how the brightness of the light affects the motion of the solar-powered insect.

Solar cells are an alternative method for generating electricity directly from sunlight. With this project, you can get down to the atomic level and learn about the world of solid-state electronics as you investigate how solar cells work. Your experiment will measure the effect of changing light intensity on power output from the solar cell. A possible variation would be to investigate the effect of changing the color of the light.
