Wily Waves: Build an Oscillating Water Column to Extract Energy from Ocean Waves

Science Fair Project Idea

Scientific Method

The ocean is a wondrous force of nature. It affects the weather, and provides us with food and renewable energy to power our lives. How can the ocean provide us with 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 create power. How… Read more

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

Winglets in Wind Tunnels

Science Fair Project Idea

Scientific Method

Winglets are the short vertical "fins" at the wingtips of some airplanes. Have you ever wondered why they are there? If you have access to a wind tunnel, you can build model airfoils with and without winglets and see for yourself. If you're really ambitious, you can also build your own wind tunnel. Read more

Have you ever been in an elevator and wondered what the many little dots on the buttons are for? You can also find these dots in public buildings on room number signs or on ATMs. These arrangements of dots are a special writing system for the visually impaired called braille. By feeling the dots with their fingers, people can read what is written on a sign or elevator button. Do you want to find out how to read with your fingers? This activity will show you how!

Write Your Own Calculator Program

Science Fair Project Idea

Engineering Design Process

When you need a calculator, what do you use? A physical calculator? An app on your phone? A web browser? What features does the calculator have? Does it just do basic arithmetic (addition, subtraction, multiplication, and division)? Can it do other mathematical functions, like square roots or exponents? Can you use parenthesis? Does it have a backspace button? That is a lot to consider for a seemingly very simple device or program! For a computer science project, can you write your own… Read more
