Science Fair Project Idea
thumbnail 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

thumbnail When an earthquake happens, how are scientists able to determine the original location of the quake? In this project, you'll use archived data from a network of seismometers to find out for yourself. You'll create your own seismograms from the comfort of your own computer with an easy-to-use webpage interface. Then you'll analyze your seismograms to determine the distance of the quake from each seismometer station. By mapping your analyzed data, you will be able to determine the location of the… Read more

thumbnail Most of us live in areas where sources of water exist nearby as oceans, rivers, lakes, ponds, streams, reservoirs, wells, or even underground streams. But in some places, like the desert, water is hard to find and a precious resource. In this environmental engineering science project, you will investigate one way that people living in arid regions can collect water inexpensively: dew traps. Read more

Science Fair Project Idea
thumbnail Native plants are important for both ecological and medicinal reasons. However, most native plants are not very well studied. One way to know more about these plants is to understand which other species of plants they are most closely related to. In this science project you will sequence part of the chloroplast genome from a native plant and use this information to determine its evolutionary relationship to other species of plants. If the plant you chose has not been sequenced before, you can… Read more

Prerequisites High school biology class; familiarity with using the PCR machine and gel electrophoresis equipment, and/or using the equipment with a mentor.
Material Availability You will need specialized pieces of equipment, including a PCR machine (thermocycler) and a gel electrophoresis apparatus. If your school does not have this equipment you might want to seek out a mentor at a junior college, university, or biotechnology company. If you have the resources you can do the DNA sequencing yourself, otherwise you can send the samples to Dr. Baysdorfer at California State University, East Bay, see Experimental Procedure for more details.
Cost High ($100 - $150)
Safety This project uses ethidium bromide, which is a carcinogen. Always wear gloves and safety goggles when handling. Dispose of the ethidium bromide according to your school or institute's hazardous waste protocols. If you have concerns, ask your teacher or mentor for advice.

thumbnail Electronic devices can be designed to detect dangerous fumes or other hazards, such as smoke or carbon monoxide. In this electronics project, you will build another potentially life-saving detector—a radon detector. Radon gas is radioactive and can pose a hazard to your health if you live in an area where it leaks from the ground. In this electronics science project, you will learn how to collect radon with an ordinary dusting cloth mounted on the intake of a fan, and then measure its… Read more

Time Required Very Long (1+ months)
Prerequisites Since the goal of this science project is to measure radon gas, you should have access to an area that has previously tested positive for radon with a commercial radon detection system. See the Experimental Procedure section for details. This is an advanced science project that will require creative problem solving on your part.
Material Availability While most of the parts for this science project are readily available, you might need to be creative about finding or making some of the parts.
Cost High ($100 - $150)
Safety Wear safety goggles when drilling and soldering. Adult supervision is recommended.
Science Fair Project Idea
thumbnail Have you ever had fun playing with sand and water, observing how little rivers you create carve their way down to the lowest point of the sandbox, backyard or beach? Some meander, others braid, and some carve a path straight down. Hyrdologists (or scientists who study water) do very much the same thing! Only they set up the model in a particular way, so observing their mini-rivers helps them answer questions about how water flow affects the environment.In this geology science project, you… Read more

Science Fair Project Idea
One thing that all living things have in common is that they grow through cell division. How is this growth regulated? Sometimes growth occurs when it is not supposed to, leading to cancer. Scientists are trying to discover how growth is regulated, hoping to find potential cures for cancer. One idea is that cells keep track of growth using special regions of the chromosome called "telomeres" that count how many divisions a cell has made. If this is true, then growth, cell division and age are… Read more

Science Fair Project Idea
thumbnail It's hard to believe that the same water that you use every day to quench your thirst, cook with, bathe in, swim in, and wash your clothes and dishes, is capable of another trick—it can make electricity! Electricity can be generated through the flow or through the fall of water. A big, fast-flowing river, for instance, contains a lot of moving energy that provides enough pressure to turn the blades of a turbine and run an electric generator. This same pressure can also be created though… Read more
