Science Fair Project Idea

Scientific Method

The funny thing about friction is that you couldn't get anywhere without it, yet it still acts to slow you down as you're getting there. Here is an easy project to measure the effects of friction. Read more

Rubber Band Elasticity and Temperature

Science Fair Project Idea

Scientific Method

Many materials expand when heated and contract when cooled. What do you think will happen to the elasticity (stretchiness) of a rubber band when it is heated or cooled to various temperatures? Read more

Why buy it when you can build it? That is the attitude you will need for this project. You have probably seen cell phone holders or stands around the house or in a car. They might seem like a very simple object, but they are a great way to learn about the engineering design process. In this project, you will design and build your own working phone stand. Read more

Combine Newton's third law of motion with engineering design in one fun lesson! Your students will learn about equal and opposite reaction forces as they design and build a bumper to protect a toy car during a crash. Read more

NGSS Performance Expectations:

MS-PS2-1. Apply Newton's Third Law to design a solution to a problem involving the motion of two colliding objects.
MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

Give Yourself a Lift: Lightening the Load with Pulleys

Science Fair Project Idea

Scientific Method

Before the Industrial Age, people relied on muscle power for moving and lifting heavy objects. Here's a project that shows you how you can use your head to make heavy lifting easier on your muscles–and your back! Read more

Applying Hooke's Law: Make Your Own Spring Scale

Science Fair Project Idea

Scientific Method

Hooke's law says that the opposing force of a spring is directly proportional to the amount by which the spring is stretched. How accurately Hooke's law describe the behavior of real springs? Can springs be used to make accurate scales for weighing objects? Spring into action and find out for yourself with this project. Read more

Do your students ever wish they could block out an annoying noise or music they don't like? In this fun lesson plan, they will design sound-insulating containers and measure how well they work using a mobile phone and a sensor app. Read more

NGSS Performance Expectations:

MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.

Solar-Powered Cars for Junior Solar Sprints

Lesson Plan Grade: 5th-8th

Help your students learn about solar energy, physical forces, and other science topics with this hands-on engineering experience. This lesson plan will show you how to get your classroom started building solar-powered cars that your students can enter, if desired, in regional Junior Solar Sprint competitions. No previous experience with electronics or building things is necessary. Get the dates and location for your regional competition. Read more

NGSS Performance Expectations:

3-5-ETS1-3. Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

Have you ever played a game at a carnival, trying to win a stuffed animal or other prize? It might look easy, until you try it. Why are those "simple" games at the fairs and carnivals so hard? Is it really lack of skill or coordination or do those concessionaires use some basic laws of science to help them set up the games in their favor? In this science activity, you will investigate how physics can help you win — or lose — at the classic game of trying to knock over a pyramid of… Read more
