Antlion Pits in Open Sand or Under Leaf Cover

Science Fair Project Idea

Scientific Method

Antlion larvae are known for their predatory ways. In sandy areas, they dig pits to trap ants or other crawling insects that happen to stumble in. This project shows you how to create a mini-environment for antlion larvae to test their preferences for pit-building sites. Read more

Are Enzymes in Laundry Detergents Effective Stain Removers?

Science Fair Project Idea

Scientific Method

Some laundry detergents have added enzymes that break down proteins, helping to remove them from the cloth fibers, and thus remove stains. You can perform a scientific test of these enzymes' stain-fighting ability. Do background research on the enzyme(s) in the detergent, and on the substances you choose for making the stains. Try to predict for which substances the enzymes will be effective. Cut a piece of light-colored cotton cloth into identical 10 cm squares. Choose different… Read more

Are Laminates Stronger?

Science Fair Project Idea

Scientific Method

If you love to hit the half pipe with your snowboard or skateboard, then you have tested the strength and durability of laminates. Laminates are sandwiches of different materials that are glued together in layers to give strength and flexibility to an object. In this experiment, you can test if laminating wood can make it stronger and able to support a heavier load. How much weight can it take before it breaks? Read more

Are More Expensive Golf Balls Worth It?

Science Fair Project Idea

Scientific Method

There is a bewildering selection of different golf balls to choose from for playing the game. Some less expensive, some more expensive, all with different claims for the advantages they will bring to your game. This project can help you determine which type of golf ball is right for you. Read more

Are Soil Microorganisms Important for Plant Health?

Science Fair Project Idea

Scientific Method

Soil may look like a bunch of dirt, but good quality soil is actually a complex mixture of dirt, nutrients, microorganisms, insects and worms. What type of benefit do these microorganisms offer a growing plant? You can test this by baking soil in the oven to sterilize and kill the microorganisms. Do plants grown in sterile soil do better than plants in unsterilized soil? What about adding worms to one plant, but not to the other. Will the plant with worms grow better? Some insects are bad… Read more

Are We There Yet? Test How Migratory Birds Navigate

Science Fair Project Idea

Scientific Method

How do you figure out how to get places? Do you ask for directions, look at a map, or consult a compass? There are many ways for people to figure out how to travel from one place to another, but how do other animals do it? In this science fair project, you'll use real data, collected by biologists, to figure out how migratory birds manage to navigate more than 2,000 miles from their breeding grounds to their wintering grounds.

Have you ever wondered how gels are made? You probably have several kinds of products around your house—some that you eat—that use gels: puddings, diapers, shoe insoles, packaging, ice cream, toothpaste and many more. A gel is a mixture of solid particles suspended in liquid. The solid particles in the gel can absorb water, causing the gel to swell and increase in volume. If you ever dunked a diaper in a tub of water, you have seen this in action; the diaper will swell as it… Read more

Around the World: The Geometry of Shooting Baskets

Science Fair Project Idea

Scientific Method

Take shots at a set distance from the basket, but systematically vary the angle to the backboard. For a basic project: How do you think your success rate will vary with angle? Draw a conclusion from your experimental results. A bar graph showing success rate at different angles can help to illustrate your conclusion. For a more advanced project: Use your knowledge of geometry and basketball to come up with a mathematical expression to predict your success rate as a function of angle… Read more

Asteroid! Identify Space Hazards with Computer Vision

Science Fair Project Idea

Engineering Design Process

Space is a dangerous place for astronauts and spacecraft. Earth's orbit is full of potential hazards like meteoroids, space debris, and other satellites that you do not want to crash into! How do scientists detect these objects in space? If you do detect an object, how can you tell what it is? In this project you will make your own computer program that can recognize and react to three different models of objects that can be found in space. No previous programming experience is required!
