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 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

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

Column Chromatography: Can you Separate the Dyes in Grape Soda Using Space Sand™?

Science Fair Project Idea

Scientific Method

What color is grape soda? If you pour it into a clear glass you can easily see it is purple, but that is usually not its natural color. Manufacturers add red and blue dye to the soda. The dyes mix together and you get purple soda. What if you wanted to un-mix the dyes, could you? Yes! In a chemistry laboratory, using a technique called column chromatography, you could separate the two dyes again. But what about at home, can you use low-tech supplies to do the same thing? In this science… Read more

Come One, Come All! Explore the Effect of Light on the Speed of the Amazing Rotating Radiometer!

Science Fair Project Idea

Scientific Method

Radiometers are fun-to-watch novelty items, but they also have a distinguished scientific history, having been studied by James Clerk Maxwell and Albert Einstein. A radiometer has a set of four vanes (like small sails) connected to a spindle that is free to rotate. When the radiometer is placed in bright light, the vanes and spindle start to spin. It looks like a magic trick, but there is a scientific explanation for this weird behavior. In this science fair project, you will experiment with… Read more

1 review

In this lesson, students will employ the enzymatic decomposition reaction of hydrogen peroxide to investigate how chemical reactions are affected by enzymes and different substrate concentrations. Students will be challenged to control the rate of the reaction by adjusting the amount of substrate and thus changing the catalase activity. Foam production, created by the enzymatic breakdown of hydrogen peroxide into water and oxygen, will function as a proxy for the reaction rate. Based on their… Read more

NGSS Performance Expectations:

HS-PS1-5. Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.

Create a Facial Recognition System with Machine Learning

Science Fair Project Idea

Engineering Design Process

Have you ever wondered how your smart devices can recognize and distinguish your face from that of others? In this project, you will explore how to create and modify a facial recognition model using a type of artificial intelligence known as neural networks. This project is designed for beginners and requires little to no coding experience. Ready to give it a shot? Read more

CRISPR Gene Editing of Escherichia coli

Science Fair Project Idea

Scientific Method

Many scientists are currently very excited about CRISPR, as it has the potential to revolutionize gene editing. But what exactly is CRISPR and what does it do? CRISPR is a novel tool in gene editing that allows the modification of genetic DNA at specific target sites in many different organisms. Researchers have high hopes that this technology can, one day, cure genetic diseases, as mutated DNA sequences can easily be corrected. In this project, you will use CRISPR to mutate a DNA sequence… Read more

Crossed Up: Does Crossed Hand/Eye Dominance Affect Basketball Shooting Percentage?

Science Fair Project Idea

Scientific Method

Everyone's used to the idea that people are either right-handed or left-handed for particular tasks. That is, one hand is preferred (or dominant) over the other for a particular task. Did you know that people also have a dominant eye? This project is designed to look for consequences of having the dominant hand and eye on the same side of the body (uncrossed) vs. having the dominant hand and eye on opposite sides of the body (crossed). Read more

Death Rays: What Duration of Ultraviolet Exposure Kills Bacteria?

Science Fair Project Idea

Scientific Method

Ultraviolet light can damage DNA molecules. If a cell's DNA repair mechanisms can't keep up with the damage, mutations are the result. As harmful mutations accumulate, the cell eventually dies. How much ultraviolet light is too much for a bacterial cell? Read more
