Science Fair Project Idea
Objects that glow in the dark hold a special place in the imagination of both children and adults. The lights go out at night, but these odd things refuse to disappear. Where does the light come from? Do they work in any climate? In this science fair project, you will make a very simple electronic device to measure the light given off by luminescent materials. The device will be used to study how temperature affects luminescence. Read more

Though the Sun provides heat and light, which are essential for life on Earth, ultraviolet (UV) rays in sunlight can cause damage to DNA. In this science fair project, you will experiment with a strain of yeast that is super-sensitive to UV light. This project will demonstrate the lethal effects of UV light when DNA damage is not repaired. Read more

The rates of some chemical reactions can actually be increased by adding light. Light sometimes interacts with one or more of the chemicals and provides an "energy boost" that dramatically speeds up a normally slow reaction. In this photochemistry science project, you will experiment with the effect of light on a chemical reaction. The reaction converts iodine, which forms a dark-orange solution, to iodide, which is colorless! Read more

"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. Read more

Have you ever had to adjust to a new time zone and noticed that it takes a while before you start to feel normal again? By shifting your sleep and activity schedule, you have altered the pattern of your body's circadian rhythms. Human beings, like many other living things, have a number of internal processes that show a distinct circadian rhythm. The most obvious is our sleep cycle, with activity during the day, followed by sleep during the night. Circadian rhythms have also been demonstrated… Read more

Have you ever thought about how fortunate you are to have safe and clean water coming out of your faucet? Many people in undeveloped nations don't have this luxury. But does that mean they can't have clean water at all? Is there an inexpensive way they could use to make their own clean water? In this microbiology science fair project, you will investigate whether or not sunlight can disinfect contaminated water. Read more

Prerequisites You should have access to a local stream or creek.
Material Availability Specialty items are required. You will need to purchase tryptic soy agar plates, droppers, and glass rods for streaking. See the Materials and Equipment section, below, for more details.
Cost Average ($50 - $100)
Safety This science fair project deals with potentially dangerous pathogens. Wear gloves when conducting the experiment. Read and follow the instructions in the . Do not drink any of the water that results from the SODIS process. See the Experimental Procedure for more information. You should always exercise caution when obtaining a water sample from a creek or a stream.
Science Fair Project Idea
The Pilobolus fungus has an interesting way of making sure the next generation has a good start on life. At high speed, the fungus shoots a sac that contains spores toward a light source. Why toward a light source? Because that is where it is most likely to find an open area with grass. Once the spore is placed on grass, it is eaten by a cow or a horse, which is a critical step in its life cycle. The spore passes through the animal's digestive track and ends up in a pile of manure. For a fungal… Read more

You have probably seen light bulbs with different wattages, for example 50 W or 100 W. Higher-wattage lights are brighter but they also consume more electrical power. Are some bulbs more efficient than others, meaning they produce more light per unit of electrical power? You can find out for yourself by making a simple photometer to compare the light output from different bulbs. This project shows you how. Read more
