Ecological Footprint Analysis

Science Fair Project Idea

Scientific Method

The sustainability of our planet's resources ultimately depends upon our actions as citizens. How much we drive, what we eat, whether we have pets, and whether we recycle are all individual actions that affect the sustainability of the Earth's resources. Learn how ecological footprinting works and figure out how big your footprint is. How big is your family's footprint? Your school? A local business? Can you propose ways to increase or decrease the size of your ecological footprint? Develop… Read more

Track the Journey of Harbor Porpoises

Science Fair Project Idea

Scientific Method

Have you ever wondered what life is like for different animals, and where it is that they roam? For example, how large is the area they live in, and why do they go to different locations? While we can set up cameras to watch animals that live on land, it can more challenging to see the lives of animals that live underwater, especially in the vast oceans. In this ocean science project, you will use satellite tracking data to learn about the activity patterns of harbor porpoises. How far do they… Read more

Lung Capacity and Age

Science Fair Project Idea

Scientific Method

Our metabolism changes as we get older, a sad fact of life that we cannot change. Old age affects our bodies in many ways. Changes in musculature, bone strength, energy, diet and breathing are some of the many ways we change as we age. You might notice that people often get out of breath when they are older and doing a physical activity. Why do some people feel out of breath, while others do not? Does this change correlate with age? Could this reflect a difference in lung capacity between… Read more

Can Machine Learning Solve a Maze?

Science Fair Project Idea

Engineering Design Process

Using artificial intelligence (AI) is easier and more accessible than ever! In this project, you will teach an AI to solve any maze. This project requires little to no coding skills; instead you will need curiosity, creativity, and a critical eye. Why not give it a try yourself? Read more

Grow Vegan Kombucha Leather

Science Fair Project Idea

Scientific Method

Do you love the look and feel of leather? Many luxury items like handbags, belts, wallets, and coats are made from leather. What if you could make your own vegan leather in a few weeks? Could it be a greener, more sustainable option than cowhide leather? In this science project, you will grow your own vegan leather from kombucha and see how different growing conditions affect the resulting leather. Read more

Fish + Food = Science of Aquaponics

Science Fair Project Idea

Scientific Method

How are we going to feed the more than 9 billion people that will live on Earth by 2050? This is a major question for farmers, ranchers, and food scientists around the globe. It's a big problem, considering that from 2017 to 2050 we will be adding 1.5 billion people and need 20% more food. Linked to this problem of producing enough food is having enough land, water, and other natural resources to make that happen. The final solution will surely be made up of many different approaches working… Read more

Taming the Tsunami: Investigating Different Structures to Reduce Tsunami Damage

Science Fair Project Idea

Scientific Method

On December 26, 2004, a magnitude 9.2 megathrust earthquake off the west coast of Sumatra, Indonesia unleashed a powerful tsunami that hit the coasts of 14 countries and caused the loss of over 200,000 lives. The devastation that the tsunami left in its wake was heartbreaking, and people across the world united to help the survivors. Tsunamis are a powerful force of nature that can change the features of a coastline and result in millions of dollars in economic loss, but can… Read more

Efficient LED Circuit Design

Science Fair Project Idea

Engineering Design Process

LED lighting can add a cool ambient effect to a room, a device, or even the inside of a car. You may know that LED lights are more efficient than incandescent bulbs, but do you know how to design and build your own LED circuit? How would you minimize power consumption and maximize efficiency? In this project you will learn how to design and build your own LED circuits so you can add LED lighting effects wherever you want. Check out this page for more LED science projects. 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

Measuring Antimicrobial Effectiveness with Zones of Inhibition

Science Fair Project Idea

Scientific Method

Have you heard that garlic powder is supposed to inhibit the growth of bacteria? Which do you think would make a better disinfectant: a solution of garlic powder or a solution of bleach? This project shows you a straightforward way to compare the effectiveness of different disinfectants (or other antimicrobial agents), by measuring zones of inhibition on a culture plate. Read more
