Science Fair Project Idea
You might not know it, but plants are able to sense their environment and actually respond appropriately. One of the key parameters that every plant must respond to is the direction of gravity: stems go up (opposite to the pull of gravity) and roots go down (in the same direction as the force of gravity). In this project, you will construct simple devices that hold several germinating seeds, which allow you to watch how growing rootlets respond as you rotate the devices, effectively altering… Read more

We all know that plants need sunlight and water to grow big and tall. But did you know that inside seeds are baby plants, and that the fragile baby plant inside the seed needs to be protected? If you've ever had a sunburn, you also know that the sun gives off harmful radiation and heat. How much radiation and heat can a seed handle? Find out using some radish seeds, an oven, and your microwave! Read more

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

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
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

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

Science Fair Project Idea
Do you realize that you are constantly bombarded by particles? You do not feel them, you cannot see, hear, or smell them, but they are always there! These particles — collectively called background radiation — might even travel through you without ever interacting with the molecules in your body. In this science project, you will build your own cloud chamber to prove the existence of background radiation. You will then use your cloud chamber to determine if the background… 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

Every day, no matter where you are, you will see people using their cell phones. People use their cell phones for more than just making calls though. They use them for texting and searching the Internet, too. But some health groups are concerned that using your cell phone too much can be hazardous to your health as it exposes your body to electromagnetic radiation. In this electricity and electronics science project, you will investigate how much radiation your cell phone emits when used… Read more
