How Do Bacteria Produce Power in a Microbial Fuel Cell?

Science Fair Project Idea

Scientific Method

Bacteria are powerful little creatures. They can dispose of contaminants, make us sick and did you know they can even generate electricity? In devices, called microbial fuel cells (MFC) they can extract electrons from their food sources such as organic materials and feed them into an electrical circuit to generate power. This way they can even turn plain soil into a source of energy! Does it matter though what kind of food the bacteria "eat"? Find out how bacteria grow in a microbial fuel cell… Read more

Butterfly Wings: Using Nature to Learn About Flight

Science Fair Project Idea

Scientific Method

Have you ever seen butterflies fluttering around outside, gliding through the air and landing on flowers? While they are delicate and fragile, butterflies are actually excellent flyers. They are so good, in fact, that scientists at Harvard University studied butterfly wing shapes as an inspiration for building a miniature flying robot. In this science project, you will do your own version of the Harvard scientists' experiment to measure the flight performance of butterfly wings. Read more

Make Your Own Wireless Alarm System

Science Fair Project Idea

Engineering Design Process

Have you ever wished you could have an alarm to prevent your little brother or sister from sneaking into your room? How about an alarm to prevent someone from stealing your favorite toy or from taking cookies out of the cookie jar? In this project you will learn how to program your own customized, wireless alarm systems to send you alerts about whatever you want! Read more

Can Biodegradable Materials Replace Plastic as Protective Food Packaging?

Science Fair Project Idea

Scientific Method

Many foods, such as fresh fruits, vegetables, or eggs, are packaged in plastic to protect them from damage during handling and transport. But is plastic the best choice? What if a more sustainable and biodegradable material could replace it? Researchers have begun exploring hydrogels—squishy materials that can hold a lot of water—as alternative packaging materials. In this science project, you will make your own hydrogels from gelatin and cornstarch and investigate what ratio of… Read more

From Contaminated to Clean: How Filtering Can Clean Water

Science Fair Project Idea

Scientific Method

Living in the industrialized world, like the United States, we are fortunate because we don't have to worry about the quality of our drinking water. Your community has the means to clean and provide water to you. But in many parts of the world, people don't have this luxury. Whether it is due to war or poverty, the lack of clean water leads to many health and social problems. In this environmental engineering science project, you will learn about different methods to filter out impurities in… Read more

Test the Webb Space Telescope's Amazing Multiple Mirrors and Sunshield

Science Fair Project Idea

Scientific Method

Can you imagine designing and building a space telescope the size of a tennis court? Believe it or not, that is someone's job! Hundreds of engineers were involved in getting the James Webb Space Telescope (JWST) into space. This telescope has the potential to enable astronomers to see light from when the Universe was first formed. No one knows what amazing discoveries this might lead to, but already, JWST has delivered astounding deep space images that offer an unprecedented look at… Read more

Asteroid Mining: Gold Rush in Space?

Science Fair Project Idea

Scientific Method

You've heard of gold mining and coal mining, but think outside the box...or the planet...what about asteroid mining? Scientists, engineers, and business people believe asteroid mining is feasible, and they are in the beginning stages of long-term plans to mine asteroids for valuable resources during space missions. You don't want to miss out on all the fun; in this science project, you will come up with your own scientific plan for an asteroid mining company. We will help get you started by… Read more

A Model of Gravity in Our Solar System

Science Fair Project Idea

Scientific Method

Why do the planets orbit the sun without flying off into space? Do they move in perfect circles or do their orbits take a different shape? And how could you possibly do a science project about any of this—you can't do an experiment with the planets! However, you can build a model of our solar system that demonstrates the concept of gravity, using balls of different sizes to represent the sun and planets. Watch the summary video for an excellent introduction to the model. Think about how… Read more

Forensics: How Does It Matter? Measure the Spatter!

Science Fair Project Idea

Scientific Method

Every criminal leaves behind evidence at the crime scene. The trick to catching the criminal is collecting all of the evidence and making sense of it. This is what the forensic expert does. In this science project you will be correlating the size of blood stains to the distance they fell, but do not get too grossed out. You will be doing it with fake blood. If you like figuring out mysteries, this is the science project for you! Read more

Water from Air: Experimenting with Dew Traps

Science Fair Project Idea

Scientific Method

Most of us live in areas where sources of water exist nearby as oceans, rivers, lakes, ponds, streams, reservoirs, wells, or even underground streams. But in some places, like the desert, water is hard to find and a precious resource. In this environmental engineering science project, you will investigate one way that people living in arid regions can collect water inexpensively: dew traps. Read more
