Growing Plants on Mars

Science Fair Project Idea

Scientific Method

To be able to live on Mars, humans need breathable air, clean water, and nutritious food. Spacesuits can provide oxygen to breathe, ice on Mars can be a source of water, but how could we get nutritious food? Today's astronauts bring food with them. But a manned trip to Mars would require food that was either successfully grown in space or on Mars, as taking the extra weight of food for such a long time—it takes 6–9 months one way—is just too costly. In this project, you will… Read more

Which Is the Better Insulation Material?

Science Fair Project Idea

Scientific Method

You've probably noticed that the price of gasoline has been going up and up lately. Heating oil will probably cost more this winter than last winter, too. Using good insulation material is one way to conserve energy and save money. What insulation materials work better than others? Read more

Rock On! Recording Digital Data with Magnets

Science Fair Project Idea

Scientific Method

This is a straightforward project that shows you how data can be digitized and stored on magnetic recording media. You'll learn how alpha-numeric characters are digitized, and you'll use bar magnets to represent the individual data "bits." You'll also learn about how much information can be stored in a small space (recording density), and how magnetic data can be erased. Read more

Comparing Different Types of Irrigation Systems

Science Fair Project Idea

Scientific Method

With heat waves impacting the world globally, many gardeners, farmers, and scientists are turning to passive irrigation systems that reduce fossil fuel emissions while keeping plants well-watered and alive in the sweltering heat. In this science experiment, you will compare and contrast the effectiveness of passive irrigation systems compared to traditional surface irrigation systems and their impact on overall plant growth.

Cold Room? Heat It Up with A Homemade Solar Air Heater

Science Fair Project Idea

Scientific Method

What do humans need to survive? We need food, water, and warm shelter. We all need a warm place to live, particularly when it's chilly outside. How do many of us warm our houses or apartments? We depend on fossil fuels to supply gas and electricity to our heaters. But burning fossil fuels to create energy is harmful to the environment. What if there was a way to warm our homes without burning fossil fuels and it was free? In this science fair project, you will build a solar air heater and see… Read more

High-Speed Magnets: Exploring Faraday's Law and Lenz's Law

Science Fair Project Idea

Scientific Method

Safety Notes about Neodymium Magnets: Neodymium magnets are very strong. Adult supervision is recommended when using them. Be careful not to drop the magnets, and do not let them slam together or fall. They may pinch your fingers, crack, or shatter. Keep magnets away from small children, pets, credit cards, and pacemakers. In the Science Buddies project Human-Powered Energy, you can learn about the basics of magnetic induction, or how moving magnets can be used to generate an… Read more

How Much Sugar Is Really in That Soda?

Science Fair Project Idea

Scientific Method

You know there is sugar in non-diet soda, but just how much sugar? Sure, you can look on the ingredients label, but how do food scientists actually measure the amount of sugar in a solution? They use a simple scientific device called a hydrometer. The hydrometer floats in the solution that is being tested, and the higher it floats, the more sugar there is! In this science fair project, you will use a precision hydrometer to measure the amount of sugar in soda. Read more

Investigating the 'Mpemba Effect': Can Hot Water Freeze Faster than Cold Water?

Science Fair Project Idea

Scientific Method

This physics project seems like it should have an easy answer. Instead, it turns out to be a great illustration of why it is important to base scientific conclusions on the outcome of controlled experiments. Things don't always turn out as we expect! Read more

Rocking the Boat

Science Fair Project Idea

Scientific Method

When a ship rocks back and forth, it can make people seasick. Even worse, it can make it dangerous for jets to land on aircraft carriers. For these reasons and many others, it's important for engineers to design bilge keels (or fins) to keep boats from rolling back and forth. Become an engineer for a day and discover the best way to keep from rocking the boat in this engineering science fair project! Read more

DNA Fingerprinting

Science Fair Project Idea

Scientific Method

Are you interested in the technical and ethical aspects of genetic screening, forensic science, and DNA fingerprinting? Scientists use different forms of a gene, called alleles, to differentiate between two fingerprints. One such sequence used in human DNA fingerprinting is the Alu repeat (a 300 base pair repetitive sequence of DNA) on chromosome 16. During evolutionary time, up to 1 million copies of the Alu repeat have become randomly inserted throughout the human genome. Within a specific… Read more
