From Black to Clear with the Magic of Photochemistry

Science Fair Project Idea

Scientific Method

The rates of some chemical reactions can actually be increased by adding light. Light sometimes interacts with one or more of the chemicals and provides an "energy boost" that dramatically speeds up a normally slow reaction. In this photochemistry science project, you will experiment with the effect of light on a chemical reaction. The reaction converts iodine, which forms a dark-orange solution, to iodide, which is colorless! Read more

From Genes to Genetic Diseases: What Kinds of Mutations Matter?

Science Fair Project Idea

Scientific Method

Our genes are made up of hundreds to millions of building blocks, called DNA nucleotides, and if just a single nucleotide of DNA becomes mutated it might cause a devastating genetic disease. But sometimes a mutation actually does no damage. What kinds of mutations have to occur to cause a genetic disease? In this science project, you will explore online genetic databases to identify how a mutation in a gene can result in a dysfunctional protein, and how other mutations may have no effect at all.

From Your John to the School Lawn: Is Recycled Water Really Safe?

Science Fair Project Idea

Scientific Method

Reclaimed (treated) wastewater can be used for many purposes, including landscape watering and freeing up valuable fresh water for other purposes (like drinking water). It's a great way to conserve water, but is it really safe? This science fair project is designed to find out. Read more

Fuel Cells—Fueling the Future!

Science Fair Project Idea

Scientific Method

You probably know that turning off the lights and the water, and not wasting paper are all ways to help the environment and conserve our resources. Did you know that another way is to use fuel cells? A fuel cell is a device that converts the energy in chemicals to electricity and it creates no pollution. The starting chemical does not have to be something complex — in fact you it can even be water! In this science fair project try your own hand at converting water to electricity with the… Read more

Game of Life

Science Fair Project Idea

Scientific Method

The Game of Life is the invention of the mathematician John Conway. It is a cellular automaton, consisting of a grid of squares that turn "on" or "off" depending on simple mathematical rules that involve neighboring squares. Depending on how the grid is first set up (i.e., the initial conditions), various interesting patterns appear. Can you write a Game of Life program in a programming language of your choice? If you are new to programming, check out these resources from the Raspberry Pi… Read more

Gamers: Myth or Man?

Science Fair Project Idea

Scientific Method

Male or female? Fat or skinny? Outgoing or quiet? What is your stereotype of a "gamer"? Do your friends have the same mental picture of gamers? How about your parents? This science fair project will help you examine whether the stereotypes of "gamers" actually matches the reality of who plays video games. Read more

Genetically Engineer Yeast to be Fluorescent

Science Fair Project Idea

Scientific Method

Can you imagine a glowing loaf of bread? You might not be able to make the whole loaf glow, but you can get baker's yeast to fluoresce! The way to do this is to modify the genetic information of the yeast organism. The technology that is used to do this is called genetic engineering. With genetic engineering, you can insert a fluorescent protein gene from a jellyfish into yeast cells, so they start glowing under blue light! Do this project to see for yourself! Read more

Genetically Modified Foods

Science Fair Project Idea

Scientific Method

Genetically modified organisms (GMOs) are organisms whose DNA have been manipulated to give them new traits. In genetically modified (GM) food crops traits like resistance to drought or pesticide might be added, or the crop may have been made more nutritious, or the taste may be altered to give you something like the impossible burger. Are there GMOs in your favorite foods? Many countries have implemented or are in the process of implementing GMO labeling on foods, but with a little bit of… Read more

Genetically Modified Organisms: Create Glowing Bacteria!

Science Fair Project Idea

Scientific Method

Have you ever heard or read about GMO? GMO stands for genetically modified organisms. Scientists can deliberately modify the DNA of organisms, such as bacteria or plants, to change their properties for a specific purpose. For example, crops can be modified to become more drought- or pest-resistant. Genetic engineering is a very powerful tool in biotechnology that has already found many different applications in agriculture, medicine, and industry. In this project, you will engineer a… Read more

Geology and Energy Resources

Science Fair Project Idea

Scientific Method

How is geology important for our energy resources? Coal, oil, and natural gas are formed by geological processes over millions of years. Certain geological formations can indicate a reservoir of coal, oil, or natural gas. Also, geothermal processes can be used as an energy resource. How are these formations identified? How are the resources extracted? You can use the National Geospatial Program to access, view, and download information from geospatial databases containing a broad spectrum… Read more
