Lesson Plan Grade: 6th-8th

Students use ultrasonic sensors and LEGO© MINDSTORMS© EV3 robots to emulate how bats use echolocation to detect obstacles. They measure the robot's reaction times as it senses objects at two distances and with different sensor threshold values, and again after making adjustments to optimize its effectiveness. Like engineers, they gather and graph data to analyze a given design (from the tutorial) and make modifications to the sensor placement and/or threshold… Read more

NGSS Performance Expectations:

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.

Bits, Bytes, and Bases: Write a JavaScript Binary/Decimal/Hexadecimal Converter

Science Fair Project Idea

Scientific Method

This is a challenging first computer science project. You'll learn the basics of how digital devices can represent numbers using only 0's and 1's, and you'll write a JavaScript program to convert numbers between binary, decimal and hexadecimal notation. Read more

Coming up with new ideas is hard! How do engineers design new things or improve existing ones? Engineers and inventors use different brainstorming techniques to help them think outside the box and come up with new ideas. In this lesson plan, your students will practice brainstorming with a method called SCAMPER. Read more

Build a Light-Up Activity Timer

Science Fair Project Idea

Engineering Design Process

Do you have trouble remembering when to stop playing and clean up? Have you ever had little kids throw a tantrum about cleaning up while you were babysitting? If so, this project is for you! You will convert a stuffed animal into a light-up activity timer. You can use the timer for different activities like play, exercise, or doing homework. What you use it for is up to you! Read more

Build an Adaptive Game Controller for a Raspberry Pi

Science Fair Project Idea

Engineering Design Process

People with limited mobility, especially in their hands, may not be able to use traditional video game controllers. Adaptive game controllers use a variety of peripherals, like larger buttons, foot pedals, or specialized joysticks, to let people with limited mobility play video games. This video shows how to build a very simple adaptive controller that works with Scratch games on a Raspberry Pi. Can you build an adaptive game controller for a hardware platform and game of your choice? If you… Read more

Build Your Own Xylophone Out of Copper Pipe

Science Fair Project Idea

Scientific Method

Did you know that making a musical instrument is not just an art, but a science, too? You can discover just how scientific by building your own xylophone (or a set of chimes) from copper pipe. First you'll need to do some research about the math and physics involved in the sounds of a xylophone. For example, there are equations that describe the transverse (side-to-side) vibrations of a pipe. These vibrations create the sounds you hear. So, to get specific sounds, xylophone makers must apply… Read more

"Diver and Lemon shark" © 2004 Hpm~commonswiki What helps SCUBA divers, sharks, fish, and other marine organisms stay in the water column? In this hands-on investigation, students will explore the concepts of buoyancy and mass to create a device to help an action figure stay neutrally buoyant, just like a scuba diver. Read more

NGSS Performance Expectations:

MS-PS2-2. Plan an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and the mass of the object.

Calling It Quits: What Is the Most Effective Way to Quit Smoking?

Science Fair Project Idea

Scientific Method

Maybe you know someone who smokes, and you want to help them to quit. They've probably already told you how hard it is to stop once a person has started smoking. This project tries to answer the question: What is the most effective way to stop smoking? Read more

Can Copper Foil Snails?

Science Fair Project Idea

Scientific Method

If you have a garden, you probably know about snails (or their shell-less relatives, slugs). You may even be looking for a good way to keep them from getting into your garden and eating up the results of all your hard work. In this science project, you will take a scientific look at one method of discouraging this garden pest. Read more

Can Garlic Prevent Crown Gall?

Science Fair Project Idea

Scientific Method

Crown gall is a plant disease caused by the soil bacterium Agrobacterium tumefaciens. This project uses tomato plants to investigate whether garlic extract can prevent crown gall infection. Read more
