Science Fair Project Idea
Farmers face a variety of challenges in their efforts to grow crops. One of the chief challenges is the presence of unwanted plants (weeds) that compete with the crop plants for water, nutrients, and light. If the weeds are not suppressed, they can reduce or completely eliminate the amount of food derived from the crop at harvest. In this biotechnology and plant science fair project, you will simulate the competition between crop plants and weeds, and determine whether the use of an herbicide,… Read more

Do you have any great-grandparents who lived through the Great Depression in the United States during the 1930's? If so, they might have stories to tell about terrible dust storms that blackened the skies, from the Midwest to the east coast. Severe drought was a factor in causing this "Dust Bowl" era, but decades of poor farming practices contributed to it, too. In this environmental science fair project, you'll learn about farming methods that help keep dirt from drying up into dust, and help… Read more

Have you ever wondered why a plant that grows well in one environment may not survive in a different environment? For example, plants that grow well in a wet jungle would probably not do so well in a dry desert, lacking enough water. This is because plants have adapted to their specific environment. Some plants have even adapted to tolerate chemicals that would usually be toxic, such as various heavy metals. In this plant biology science project, you will investigate whether different… Read more

Have you ever experienced heartburn after eating a large, greasy meal? Or have you heard of someone complaining about heartburn pains? It's very common; over 60 million people in the U.S. have heartburn at least once every month. Heartburn pain usually results from stomach acids escaping from the stomach and irritating the esophagus above it. Luckily, there are medical drugs, called antacids, which can help relieve heartburn pain. But how do antacids work, and how effective are they? In this… Read more

If you have ever prepared a cup of coffee or tea with sugar, you have probably seen that the grains of sugar quickly dissolve and completely disappear in hot water. But sugar is not the only type of solid that can readily dissolve in a liquid. In fact, there are some types of rocks that can be dissolved by common liquids. It might be hard to imagine large, hard rocks being eaten away by some ordinary fluids, right? But it actually happens all the time! In this geology science project, you will… Read more

You have probably seen it on You Tube™ — the exploding Coke® and Mentos® experiment. But what is it that makes the reaction happen, and what factors cause a larger or smaller eruption? In this science project, you will see if using crushed Mentos candies, instead of whole Mentos candies, will affect the reaction. Read more

Every spring, gardeners around the world get ready to plant their summer gardens. They turn the soil over in their garden plots and add nutrients to the soil. Then they plant their seedlings and wait for nature to provide a bounty of fruits, vegetables, and flowers. But nurturing the garden doesn't stop there. In order to get lots of fruits and vegetables, the gardener must eliminate factors that can hurt the plants. Sometimes, chemicals in the soil from other plants and trees can hurt a… 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

Interested in helping the environment, and don't mind getting dirty? In this project you get to mix it up with earthworms, soil, and various types of organic kitchen scraps. The basic idea is to set up small earthworm colonies to compost different types of food waste. You test the soils in each type to see how diet affects both the earthworm population and the nutrients they put back into the soil. This project takes a little time, but it's worth it. You'll help the environment and learn… Read more
