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 When a ship rocks back and forth, it can make people seasick. Even worse, it can make it dangerous for jets to land on aircraft carriers. For these reasons and many others, it's important for engineers to design bilge keels (or fins) to keep boats from rolling back and forth. Become an engineer for a day and discover the best way to keep from rocking the boat in this engineering science fair project! Read more

Science Fair Project Idea
thumbnail Do you love roller coasters and other kinds of exciting rides? Are you a thrill-seeker? Well, this is the science fair project for you! What makes a ride so thrilling that people want to ride it over and over again even though it scares them? Is it the speed, the twists and turns, the vertical drops? In this science fair project, you will build and use an accelerometer to figure out what makes a roller-coaster ride worth standing in line for. Oh, and if Mom and Dad ask what an amusement park… Read more

Science Fair Project Idea
thumbnail The ocean is a wondrous force of nature. It affects the weather, and provides us with food and free and renewable energy to power our lives. How can the ocean provide us with free and renewable energy? One way is to extract the energy that is in the waves. There are many kinds of power systems that can be installed to extract energy from the waves, depending on the location. In this energy and power science project, you will build and test a simple model of an oscillating water column device to… Read more

Time Required Average (6-10 days)
Prerequisites You should have fairly easy access to the ocean or to a deep body of water. Find a location where the surface of the water is within easy access of a pier, a dock, or a boat slip, and where the water is about 5 feet deep. You could also do this project in a swimming pool.
Material Availability See the Materials and Equipment list for more details.
Cost High ($100 - $150)
Safety Be sure to wear safety equipment, such as safety goggles and gloves, when working with power tools and other equipment. Parental supervision is required.
Science Fair Project Idea
thumbnail The world's oceans are home to the most strange and amazing creatures. What do scientists know about these deep-sea animals and how can they study them easily? One way to learn about these animals in their homes is to use underwater robots. Underwater robots can record data that would be difficult for humans to gather. But what are robots and how are they made? In this robotics engineering project, you will discover what makes up a simple robot and build and test your own underwater robot. Read more

- Less Details
Time Required Average (6-10 days)
Prerequisites None
Material Availability To build an underwater robot you will need a motor and a model boat propeller. See the Materials and Equipment list for details.
Cost Low ($20 - $50)
Safety You will need glue and epoxy to waterproof the motor for the robot. Follow the instructions that come with the glue and epoxy and always work in a well-ventilated area. If you have a latex allergy, you will have to exercise great caution with the balloon and ask a volunteer to help you. Keep fingers away from the spinning propeller to prevent injury. Do not test the robot in saltwater.
Science Fair Project Idea
thumbnail Did you know that throwing, kicking, and punting a football all involve the science of projectile motion? A star NFL® quarterback, kicker, and punter each need to have a very good understanding of how a football moves through the air in order to help them win games. In this science project, you will set up a rubber band-powered catapult to represent a field goal kicker, and study how changing the distance from the goalposts affects how hard it is to accurately kick a field goal.
