This activity demonstrates how potential energy (PE) can be converted to kinetic energy (KE) and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by understanding conservation of energy and using the equations for PE and KE. The equations are justified as students experimentally measure the speed of the pendulum and compare theory with reality.Engineering Connection Mechanical engineers design a wide range of consumer and… Read more

NGSS Performance Expectations:

MS-PS3-5. Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object.
MS-PS3-2. Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system.

Take a Hike: Train Your Robot Dog to Walk with a Virtual Leash

Science Fair Project Idea

Scientific Method

Have you ever walked a dog on a leash? Depending on how well-behaved the dog is, it can be very easy or very difficult. It would be great if you could tell your dog exactly how to behave, right? With that in mind, in this project you will build a robotic dog using a LEGO® Mindstorms® kit that you can teach to "walk" using the beam from a flashlight as a virtual leash. But your robot dog will not know how to walk on a leash on its own — you will have to "train" it, just as you… Read more

Tasty Arrangements: How to Position Food in Microwave Cooking

Science Fair Project Idea

Scientific Method

When you think of successful inventions from the 1900's that have dramatically changed how people live, what comes to mind? The car? Radio? TV? The computer? What about the microwave oven? You might not remember a time when microwave ovens were not a standard part of most kitchens, but your parents or grandparents probably do. They can remember when heating leftovers took a good 30 minutes in a traditional oven. Or thawing a food from the freezer meant leaving it in the refrigerator overnight.… Read more

Tee Time: How Does Tee Height Affect Driving Distance?

Science Fair Project Idea

Scientific Method

If you're an avid golfer, this might be a fun project for you. When you're setting up to tee off out on the course, how much attention do you pay to putting the tee in the ground? The height of the tee can affect both where in the swing the club makes contact and where on the clubface the ball makes contact. Are you placing your tees at the right height to get the most distance from your swing? Read more

Tee Time: How Fast is Your Golf Swing?

Science Fair Project Idea

Scientific Method

The goal of every golfer is to hit the golf ball as far as possible down the fairway. A key factor in determining the distance that the ball will travel is the velocity of the club when it strikes the ball. In this sports science fair project, you will determine exactly how distance is related to club velocity. Time to tee off! Read more

Testing Behavioral Incentives

Science Fair Project Idea

Scientific Method

What motivates you to clean your room/mow the lawn/wash the dishes (substitute your own responsibility at home)? What motivates you to do something you really like to do? Or think about this: you'd like to get your younger brother or sister to do you a favor. What strategy works best? Here is a project designed to test which incentive strategy works best for encouraging small children to complete a task. Read more

Testing the Strength of Martian Bricks

Science Fair Project Idea

Scientific Method

For a colony of humans to survive and thrive on Mars, they will need to make the most of what is available on Mars. We know from prior space missions what the Martian ground cover looks like. In this project, you will see if this ground cover can be transformed into strong construction material. The first requirement for construction material is that it is strong so it does not collapse under its own weight. Because the mass of Mars is about 10 times less than the mass of Earth, its… Read more

That's a Pretty Tough Baby! A Study of Gender Stereotypes in Children

Science Fair Project Idea

Scientific Method

Have you ever seen a baby in the park and wondered if it was a boy or a girl? Maybe once you found out the gender, you thought how sweet, mischievous, or cute the baby was. But wait…do you think that the words you used to describe the baby might be based on your own gender stereotypes? A gender stereotype is when you expect someone to act a certain way simply because he or she is a boy or a girl. In this human behavior science project, you will investigate whether young children use gender… Read more

The Art & Science of Making Yummy Yogurt

Science Fair Project Idea

Scientific Method

Yogurt is a very versatile dairy product. It's yummy eaten straight from the container, it is good for your digestive system, and it can be used in several ways for cooking. There is historical evidence that yogurt-making developed 4,500 years ago! Humans depended on yogurt-making as a way to preserve milk. Yogurt is the result of bacterial fermentation of milk. In fermentation, the bacteria consume the milk sugar, lactose, and produce lactic acid. The end-product is a thick, creamy, and tangy… Read more

The Chills and Thrills of Roller-Coaster Hills

Science Fair Project Idea

Scientific Method

Think it's a good idea to stream music, watch videos, or check social media while doing homework? 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… Read more
