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

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.
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.

When your students think of robots, they probably think of materials like metal or plastic—but what about paper? In this lesson plan, your students will learn to make robotic parts from readily available classroom materials. Optionally, they can apply the engineering design process to improve the design or come up with their own designs. Read more
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

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

Add a twist to a traditional "build a catapult" engineering project with this fun lesson plan based on the 2018 Engineering Challenge. Your students must build a device to launch a ball as far as possible—but they also have to build another device to catch it! With detailed rules and guidelines for a class-wide competition, this lesson is a great way to teach your students about the engineering design process. Read more
NGSS Performance Expectations:
  • MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
  • 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.

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.

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

In this fun engineering lesson plan, your students will build devices from paper, tape, string, and paper clips to pick up and retrieve a ping pong ball. The challenge is to pick up the ball from as far away as possible! Elementary school and high school versions of this lesson plan are also available. The 2023 competition is over, but you can see what students built and learn about the winners on the 2023 Engineering Challenge summary page. Read more
