Science Fair Project Idea

Scientific Method

Plants need nitrogen to grow healthy stems and leaves. Although nitrogen is the most abundant element in the air we breathe, that form of nitrogen cannot be used by plants. Nitrogen contained in fertilizer, on the other hand, is readily taken up by plants. In this experiment, you will compare plants grown without nitrogen fertilizer to plants grown with nitrogen fertilizer. Read more

An Experiment on Seed & Fruit Dispersal

Science Fair Project Idea

Scientific Method

Up, up, and away! If you have ever made a wish and blown the fluff of a dandelion, you have witnessed how some plants are adapted to spreading their seeds using the wind. The tiny, furry parachute allows the seeds to be picked up by the wind and to be carried far away from their parent plant. In this experiment, you will make models of seeds and fruit to investigate dispersal by wind and to evaluate the relationship between the structure of the seed and its ability to be dispersed by the wind.

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

Apparent Motion & Animation

Science Fair Project Idea

Scientific Method

Have you ever heard the phrase, "Seeing is believing"? Well, it is more accurate than you might think! In this science project, you can investigate the phenomenon of apparent motion by making your own flip-book animations Read more

Archimedes Squeeze: At What Diameter Does an Aluminum Boat Sink?

Science Fair Project Idea

Scientific Method

Where do you get your best ideas? At school with your friends? When you are out for a bike ride? Over 2,200 years ago, a scientist named Archimedes got one of his best ideas when he sat down in his bath. Eureka! He went running through the streets without even bothering with his clothes. What was he so excited about? He had discovered that when objects, like his body, are placed in water, water is pushed out of the way. Have you noticed that, too? The weight of the water that is pushed out of… Read more

Are Childproof Containers Really Childproof?

Science Fair Project Idea

Scientific Method

Have you ever woken up in the middle of the night just not feeling well? Maybe your mom or dad gave you some medicine and you felt better after taking it. Medicine is a great tool in the fight against an illness, but medicine can be a poison if too much is taken. Similarly, household products can clean your home and make it smell great, but if eaten, can be poisonous. That is why most medicines and household products are stored in childproof containers. But are childproof containers really… 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 There Bugs Under Your Feet?

Science Fair Project Idea

Scientific Method

Look out! When you walk on the grass, you are squishing millions of micro-invertebrates! Just kidding, these animals are too small to squish. Learn how to catch them by making a Berlese funnel in this fun project that will teach you about soil. Read more

Are There Dangerous Levels of Lead in Local Soil?

Science Fair Project Idea

Scientific Method

The element lead is a neurotoxin that is particularly dangerous to young children. Among other uses, lead compounds were common paint additives until being phased out for safer titanium-based additives beginning in the 1960's. Lead compounds were also added to gasoline to prevent engine knocking, until being phased out beginning in the 1970's. Although paint and gasoline sold today no longer contain lead, soil can have contamination from older sources of lead, such as paint from old buildings.… Read more
