Wind Turbine Efficiency

Science Fair Project Idea

Scientific Method

Try different wind turbine/propeller (chord length, pitch) designs by making models from balsa wood. Connect the spinning axle to a DC motor and measure the voltage produced across a resistor to measure power output. Use fan as wind source. (Judge, 2004) Read more

NASA Asteroid Database: What Can You Learn About Our Solar System?

Science Fair Project Idea

Scientific Method

Did you know that in addition to the Sun and planets, our solar system is filled with millions of asteroids, which are chunks of rock left over from the early days of its formation, or from collisions between larger objects like planets? Agencies like NASA track asteroids, not only because they might pose a threat to humanity by colliding with Earth, but because they can provide us with information about the history of our solar system, and even be useful for mining raw materials in space! In… Read more

Why Do Birds Fly in a V-formation?

Science Fair Project Idea

Scientific Method

Have you ever wondered why geese fly in a V-formation? In this science fair project, you will build a wind tunnel to test how the formation of birds in flight actually affects their flight efficiency. Read more

Native Landscapes

Science Fair Project Idea

Scientific Method

Do your parents like to garden? Then you might have a beautiful lawn surrounded by flowers, or a vegetable garden. Humans have been introducing plants to our landscapes for centuries, which has dramatically altered the natural habitat of many environments. Chances are, the landscape you live in is not a natural landscape. One movement is to restore these habitats by re-introducing native plants. Conduct a survey in your area looking for native and non-native plant species. You can take… Read more

Rad Radishes: Effects of Irradiation on Seed Germination

Science Fair Project Idea

Scientific Method

DNA is the "instruction manual" for the successful growth of a living thing, from a single cell to a mature adult. When the DNA of an organism is somehow damaged, it can have an impact on the organism's development over time. In this plant science fair project, you will track how irradiation (exposure to radiation) of radish seeds affects germination (sprouting of a seedling from a seed). Read more

Motorizing a Robotic Hand

Science Fair Project Idea

Scientific Method

Imagine how cool it would be to have your own motorized robot hand. Well, stop imagining and turn that daydream into reality! Start out by designing and building a robot hand. The Science Buddies project Grasping With Straws: Make a Robot Hand Using Drinking Straws shows you a simple way to make a robot hand with drinking straws, or you can design a robot hand from any other materials you think are suitable. Your hand design will need sewing threads, or some other mechanism, for motors to… Read more

Do Plants Promote Pesticide Breakdown?

Science Fair Project Idea

Scientific Method

When pesticides are applied to protect crops, run-off of potentially harmful pesticides is a major problem. Can water plants such as hardstem bulrush, common cattail, parrotfeather and smooth scouring rush promote pesticide breakdown? If so, diversion of irrigation run-off into plant-filled ponds could help reduce pesticide pollution. Mix malathion at 12.5% of the recommended application strength (to simulate dilution by rain or irrigation water). Use 5-gallon buckets for testing various… Read more

Investigate the Vitamin C Level in Bell Peppers During Various Stages of Ripeness

Science Fair Project Idea

Scientific Method

Vitamin C is a water-soluble vitamin that has many functions in the body. Vitamin C is needed to bolster the immune system. It is an antioxidant that protects LDL cholesterol from oxidative damage, and it is needed to make collagen, a substance that strengthens many parts of the body, such as muscles and blood vessels. Our bodies do not make vitamin C, so we must get it from dietary sources. Citrus fruits, carrots, avocados, and spinach all have vitamin C. Bell peppers, like the ones shown in… Read more

Testing a Parabolic Reflector with Light from an LED

Science Fair Project Idea

Scientific Method

You can see examples of parabolic reflectors in flashlights, car headlights, satellite TV antennas, and even on the sidelines at football games. How do these "dish" antennas work to gather signals? What is the best position for placing the detector for these antennas? In this project, you can use an LED and a simple photodetector to find out for yourself. Read more

Science Fair CSI: Can You Predict the Spatter?

Science Fair Project Idea

Scientific Method

There is evidence to be gathered at every crime scene. The hard part is making sense of it all. That's where crime scene investigators and forensic scientists come in. In this science fair project, you will investigate blood spatter using fake blood. Your job, as an impartial scientist, is to deliver facts so that justice can be served. Are you up to the challenge?
