Picture This: Building a Cell Phone Microscope

Science Fair Project Idea

Scientific Method

Imagine you are on a trip and see something interesting that you want to share with your friends. What do you do? You take a picture with your cell phone and e-mail it to them, of course. But did you realize that the same technology can be used to save lives? Using their cell phones modified as inexpensive microscopes, medical personnel can look at blood smears to help diagnose diseases like malaria and cholera. In this photography science project you will build a simple and inexpensive cell… Read more

Pounding Papyrus: How Ancient Egyptians Made the World's First Paper

Science Fair Project Idea

Scientific Method

It's hard to imagine a world without paper. You wouldn't have things like books, cards, comics, newspaper, construction paper, notebooks, cereal boxes, or that nice sound of shredding wrapping paper on your birthday. There was a time, though, when the only thing people had to write on were slabs of soft, squishy clay. When these slabs dried in the sun, they preserved simple ideas, but they were heavy, like carrying around a load of rocks. Not exactly easy to put in your pocket and carry around.… Read more

Predicting Future Water Quality with Machine Learning

Science Fair Project Idea

Scientific Method

Understanding the water quality of our rivers, streams, and lakes is critical for maintaining healthy ecosystems and sources of drinking water. Dissolved oxygen is one key water quality measurement that impacts aquatic life. But how can we predict how water quality might change in the future so we can intervene to keep our water healthy? With machine learning! In this project, you will gather water quality data for a location of your choice and use a random forest model to predict future… Read more

Predicting Wildfire Intensities and Locations with AI

Science Fair Project Idea

Scientific Method

Have you ever wondered what causes wildfires and how resources are allocated to prevent their spread? In this science project, you will use machine learning to predict areas of wildfire susceptibility and their intensities. Read more

Proving Charles' Law: Volume vs. Temperature of a Gas at Constant Pressure

Science Fair Project Idea

Scientific Method

This is a modern version of a classic experiment by Jacques Charles on the volume of a gas at different temperatures. Charles discovered the relationship between volume and temperature of gases that now bears his name. This project shows you a simple method for re-creating this famous experiment. Read more

Riding on Air—Build a Real Hovercraft

Science Fair Project Idea

Scientific Method

Looking for an exciting new mode of transportation? In this science fair project, you will build a working hovercraft that will glide over surfaces on a cushion of air. And it's simpler to build than you might think! 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

Have you ever wondered why rubbing a balloon or a blanket—or even a winter hat—on your head makes your hair stand up? The effect is due to static electricity, but how is the static electricity made, and why does it make your hair stand on end? Static electricity is the buildup of electrical charge in an object. Sometimes static electricity can suddenly discharge, such as when a bolt of lightning flashes through the sky. Other times, static electricity can cause objects to cling… Read more

Rubbing Up Against Static Electricity

Science Fair Project Idea

Scientific Method

A tried and true balloon activity is to rub a balloon on your head to make your hair stand up. How does the rubbing build up static electricity? Do this experiment to see if the number of rubs makes a difference. Read more
