Science Fair Project Idea
thumbnail Did you know that there is plastic in the ocean? It probably isn't too hard to imagine that some of the plastic that litters roadways, sidewalks, and parks finds its way into the ocean. So, how much do you think is in there? Hundreds of pounds of plastic? How about thousands of pounds? No one knows for sure, but estimates, based on scientific surveys, suggest the amount is in the range of millions of pounds of plastic! Of course, the ocean is big, over 300 million square kilometers, so… Read more

Prerequisites To do this science project you will need access to an urban or suburban community. Rural communities may not be suitable for this project as they are unlikely to have a stormwater drainage system.
Material Availability See the Materials and Equipment list for details.
Cost Low ($20 - $50)
Safety Use caution when using the utility knife. Adult supervision is recommended.

thumbnail This project shows you how to build a simple model system to simulate underground water flow. Underground water flow is important for understanding replenishment of underground aquifers, migration of underground contaminant plumes, and cave formation. With your model system, you can simulate various underground conditions, and test your predictions about the effects they have on water flow. 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

Science Fair Project Idea
thumbnail Renewable energy is the energy that is extracted from natural sources, such the Sun (solar), earth (geothermal), wind, and water (hydropower). These sources are renewable because they can be replenished by the same natural sources within a short period of time. Hydropower energy is extracted from moving water, like ocean wave energy and tidal energy. In this energy science fair project, you will make a model of a tidal barrage (also known as a dam) and investigate how emptying the tidal barrage… Read more

Science Fair Project Idea
thumbnail People often call cardiovascular disease a "silent killer." This disease sneaks up and causes damage, but patients don't realize it—until serious symptoms start. That is why physicians recommend keeping your cardiovascular system healthy. A healthy cardiovascular system gives us the energy and the stamina to do all of the things that we want to accomplish, such as do our best in school and perform well in sports. But what makes a cardiovascular system unhealthy, and what are the… Read more

Science Fair Project Idea
thumbnail If you'd like to investigate the physics of amusement park rides, then this project is for you. You'll build a roller coaster track for marbles using foam pipe insulation and masking tape, and see how much the marble's potential energy at the beginning of the track is converted to kinetic energy at various points along the track.

Science Fair Project Idea
thumbnail In this project, you'll investigate the physics of standing waves on guitar strings. You'll learn about the different modes (i.e., patterns) of vibration that can be produced on a string, and you'll figure out how to produce the various modes by lightly touching the string at just the right place while you pick the string. This technique is called playing harmonics on the string. By the way, we chose a guitar for this project, but you can do the experiments using any stringed instrument, with… Read more

This is a great project for a musician who is interested in the physics of stringed instruments. If you've every played an acoustic guitar, you may have noticed that picking a single string can make one or more of the other (unpicked) strings vibrate. When this happens, it's called sympathetic vibration. What intervals lead to the strongest sympathetic vibrations? Find out for yourself with this project. Read more

Prerequisites To do this project, you will need a properly tuned acoustic guitar (or other acoustic stringed instrument). You'll need to know enough about playing the instrument to produce clear, ringing tones by picking (or plucking) the string while changing its effective length by fretting (or fingering) it.
