Do you play or watch a sport where you use something (other than your hands or feet) to hit a ball? Golf, baseball, tennis, hockey—there are many different sports where players use something to hit a ball or a puck. In this activity you will design, build, and test your own sports equipment made from recycled materials. Read more

Building a Model Hydraulic Knuckle Crane

Science Fair Project Idea

Scientific Method

A ship is a busy place. When out to sea, naval, research, and fishing vessels pull or push heavy loads, like research equipment and crab pots, into and out of the water. But equipment and pots can weigh hundreds of pounds. So how does a ship's crew lift loads efficiently and accurately? With a hydraulic knuckle crane, of course. But what is hydraulics and why does hydraulics make certain tasks easier? Hydraulics is the study of liquids and their mechanical properties: how they move, resist… Read more

Building Banjos

Science Fair Project Idea

Scientific Method

The banjo's roots trace all the way over to Africa. The unique sound that a banjo makes depends, in part, on the resonator. The purpose of the resonator is to amplify and project the sound that is made by strumming and plucking the strings. In this music science fair project, you will experiment with a resonator on a banjo and see if you can hear the difference in sound. Read more

A day at the beach is a wonderful way to spend time with your family and friends. You can swim, play games and build sand castles. But have you ever wondered how the beach you are standing on came to be? How, for example, did all of that sand get there? Beaches are formed and continually changed by the ocean's waves moving rock particles onshore, offshore and along the shore. In this activity, you can investigate how beach formations are made by some parts of a beach that can resist erosion… Read more

If you have ever built a tower with blocks, you have probably knocked it over—either on purpose, or by accident. Sometimes your tower gets too tall and wobbly, and you just cannot keep it standing! In this activity, you will learn about the trade-offs you need to make when building a tower that is both tall and stable. Read more

Building Personal Medicine Apps to Help Patients

Science Fair Project Idea

Engineering Design Process

Remembering to take medication or perform a test regularly, consistently, and at specific times can be difficult for elderly people with short-term memory loss, or teenagers absorbed in activities. With mobile devices becoming our constant companions, could a smartphone or tablet offer a solution? The Massachusetts Institute of Technology (MIT) has created a simple tool making it possible for anyone who has a computer and Internet access to create a reminder app. It is easy, quick, and… Read more

Buoyancy of Floating Cylinders

Science Fair Project Idea

Scientific Method

This science project presents an interesting puzzle. A disk of wood will float face-up; that is, with its circular cross-section parallel to the surface of the water. A long log of wood, however, floats on its side with the circular cross-section perpendicular to the surface of the water. If you think about it, disks and logs are both cylinders. Is there some intermediate length of cylinder that floats with the circular cross-section at a tilted angle? Try this experiment to find out! Read more

Burning Calories—Literally!

Your students might know that they can burn calories, but do they know what a calorie really is? In this fun lesson plan, your students will measure the energy content of food by literally burning it using a device called a calorimeter that they will design and build themselves. This will get your students thinking about the chemistry of energy transfer as well as good nutrition, and gives a whole new meaning to the phrase "burning calories!" Read more

NGSS Performance Expectations:

MS-PS3-3. Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer.
MS-PS3-4. Plan an investigation to determine the relationships among the energy transferred, the type of matter, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample.

Computational thinking is a problem-solving process that is used in everyday life as well as computer programs. In this lesson, students apply their computational thinking skills to explore the life cycle of a butterfly. They'll create an algorithm, or set of instructions, to model the life cycle of a butterfly. They will write this algorithm using conditionals and then program it on a computer. Learning Objectives Students will: Analyze the life cycle of a butterfly. Develop an algorithm… Read more

Camera 'Shakes'

Science Fair Project Idea

Scientific Method

You can compare the picture quality for photos taken at different shutter speeds with the camera handheld vs. with the camera on a tripod. (This is best done with a camera that has manual exposure control.) Read more
