Science Fair Project Idea

Scientific Method

Does listening to classical music help or hinder concentration and performance on cognitive tasks? You'll need help from a teacher to design two short, age-appropriate worksheet tests for this experiment. The tests should be of equal difficulty. You'll also need the cooperation of several additional classroom teachers in order to test enough students (at least 50-100, see the Science Buddies resource: How Many Participants Do I Need?). Half the students will take test A while listening to… Read more

Classify Animals with Machine Learning

Science Fair Project Idea

Engineering Design Process

How do you tell the difference between a bird and a fish? Birds tend to have feathers and can fly, while fish have no legs and can breathe underwater. In this project, you will explore how to create a decision tree using machine learning that can classify different animals based on multiple characteristics. This project is designed for beginners and requires little to no coding experience. Ready to give it a shot? Read more

Classify Spam Emails with Natural Language Processing

Science Fair Project Idea

Engineering Design Process

Have you ever wondered how your phone or email automatically detects and filters junk messages into spam? This feature helps ensure you focus on the messages that truly matter. In this project, you’ll build your own spam detector using natural language processing (NLP) techniques. Read more

Clean Up The Water with a Trash-Skimming Robot

Science Fair Project Idea

Engineering Design Process

Engineers are trying to tackle the world's ocean pollution problem using robots. Some robots, like Mr. Trash Wheel and the ship featured in this Mark Rober video, are stationary and collect trash as it flows out of rivers before it gets into the ocean. Others, like the Jellyfishbot, are mobile and can squeeze into narrower spaces to collect trash: Can you build and test your own trash-skimming robot? If you do not have access to a natural body of water to test it in, you can use a bathtub or a… Read more

Click a Button Without Your Hands: Design a Puff Switch

Science Fair Project Idea

Engineering Design Process

Have you ever wondered how you could push a button without using your hands? How would you type on a computer or play a video game? You could use a puff switch - an electronic switch activated by blowing into a straw. This type of assistive device can help users with limited mobility or physical disabilities do everything from using a computer to steering a wheelchair. In this project, you will design, build, and test a puff switch that is connected to a tiny programmable board that you can use… Read more

Climb Every Mountain with Your Own LEGO® Cable Car

Science Fair Project Idea

Engineering Design Process

If you ever rode in a cable car, ski lift, or gondola, you know they make moving over obstacles like lakes, valleys, rivers, or even up steep mountains seem easy. Though it would be pretty difficult to build a full-size cable car in your home, if you have a Mindstorms® kit, you can build a working-model cable car of your own. The engineering challenge is to build a LEGO® cable car that can travel across a string you have suspended somewhere in your house (between two pieces of… Read more

Coffee Buzz: How Does Caffeine Affect the Physiology of Animals?

Science Fair Project Idea

Scientific Method

Caffeine is a type of chemical called a stimulant. When you drink a caffeinated beverage, the caffeine enters into your blood stream dilating the capillaries and causing blood to flow more quickly. This gives your body a feeling of speeding up which can cause the jitters and wakefulness. How does caffeine affect the physiology of other animals? You can use over-the-counter caffeine supplements, like Vivarin, to test the effects of caffeine on animals. Try dissolving the caffeine in… Read more

Cold Pack Chemistry: Where Does the Heat Go?

Science Fair Project Idea

Scientific Method

Instant cold packs are popular with coaches and parents for treating minor bumps and bruises. The instant cold packs are not pre-cooled—you just squeeze the cold pack and its starts to get cold. So how does it work? In this chemistry science fair project, you will investigate the chemical reaction that occurs in instant cold packs. Read more

Color Mixing with Red, Green, & Blue LEDs

Science Fair Project Idea

Scientific Method

This is a good project for someone who is interested in both electronics and color vision. The equipment needed is on the expensive side, but if you continue studying electronics, you can use it again and again. Read more

Colorizing Images from the James Webb Space Telescope

Science Fair Project Idea

Engineering Design Process

The James Webb Space Telescope (JWST) has shown us some amazing images of space, like its first "deep field" image (Figure 1). The JWST sees the universe in the infrared part of the electromagnet spectrum, which is not visible to the human eye. How, then, does it produce color images like the one in Figure 1? Scientists must colorize the images, or apply "false color." They map different bands of the infrared spectrum to colors of visible light, resulting in an image humans can view. Luckily,… Read more
