Science Fair Project Idea
It's true that the light from the Sun provides the heat and light we need to survive here on Earth, but it also poses a threat. Ultraviolet (UV) rays in sunlight cause damage that can lead to early skin aging and even skin cancer. In this science fair project, find out when you need the most protection from UV rays by using a personal UV monitor to measure how the level of ultraviolet light changes during different parts of the day.

Science Fair Project Idea
Ultraviolet light can damage DNA molecules. If a cell's DNA repair mechanisms can't keep up with the damage, mutations are the result. As harmful mutations accumulate, the cell eventually dies. How much ultraviolet light is too much for a bacterial cell? Read more

Cost Average ($50 - $100)
Safety Adult supervision required. Read and follow the safety note below on ultraviolet light. Follow standard precautions for handling bacterial cultures.
Science Fair Project Idea
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

Safety Gloves and safety goggles are required. Oxalic acid is toxic and an irritant. Avoid breathing oxalic acid dust and avoid contact with skin. Ammonia is an irritant. Iodine is also an irritant and stains clothes and skin. Adult supervision is required.
Science Fair Project Idea
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

Do you think worms are gross? Or that they are only good for birds or fish to eat? Well, in this zoology science project, you will find out that this lowly animal helps to put food on your table, too, by all the hard work that it does in the dirt. In this science project, you will discover in what kind of soil it likes to do its work. It is wiggly good fun! Read more

Science Fair Project Idea
A nice hot cup of tea sure can wake and warm you up in the morning. In this science fair project, you will investigate the chemistry of tea. The longer you steep a tea bag in hot water, the stronger the tea will be. But how does the strength of the tea change with longer brewing time? In this food science project, you will make a very simple electronic device to measure the strength of tea. The device will determine how strong the tea is by measuring the amount of light the tea absorbs. Read more

Safety No issues
Science Fair Project Idea
Have you ever seen a product labeled "biodegradable" or "compostable" and wondered just how well it decomposes? A lot of different products claim to be biodegradable or compostable, such as food containers, bags, packaging materials, and spoons and forks. Not only do they clearly come in different shapes and sizes, but they are made of different materials as well. Do they decompose differently, and, if so, which decomposes the fastest? In this science project, you will make your own indoor… Read more

Science Fair Project Idea
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
