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.

Study the Effect of Fertilizers on Algal Growth

Science Fair Project Idea

Scientific Method

You might not know it, but a lake without algae would be a very dull place. If there were no algae, there would be no small animals feeding on the algae, and there wouldn't be any fish eating the small animals that eat the algae. You might conclude that since some algae is good, more algae is even better, but algae growth has a down side. If there is too much algae, they can deplete the oxygen in the water, killing off other species in the water. What is one culprit that leads to algal growth?… Read more

Going Green as You Clean: Are 'Green' Detergents Less Toxic Than Conventional Detergents?

Science Fair Project Idea

Scientific Method

There is strong interest in "going green," including using products that cause less environmental damage when they are disposed of. In this environmental sciences project, you will compare the toxicity of "green" and conventional liquid detergents using worms as test organisms. Read more

Heavy Metals and Aquatic Environments

Science Fair Project Idea

Scientific Method

You might know that lead can be toxic, and that you can get lead poisoning from eating or inhaling old paint dust. Lead is called a heavy metal, and there are other sources of heavy metals that can be toxic, too. Silver, copper, mercury, nickel, cadmium, arsenic, and chromium are all heavy metals that can be toxic in certain environments. In this experiment, find out if one common heavy metal, copper, can be toxic to an aquatic environment. 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

Chemical Analysis of Rainwater

Science Fair Project Idea

Scientific Method

Here is an interesting project that could be approached from several different scientific angles: Environmental Science, Weather & Atmosphere, Chemistry, or Plant Biology. You can probably think of your own variations to emphasize the scientific area that most interests you. Read more

Sandy Beaches and Reef Disturbance

Science Fair Project Idea

Scientific Method

When you go to the beach, you may not know if the beach is natural or man-made. The popularity of sandy beaches prompted developers in the past to bring in sand to cover rocky shorelines and turn them into more popular sandy beaches. However, the actions of the tides, currents and waves carried the extra sand out into the reef, endangering the reef and the creatures living on it. You can use a water table to conduct experiments with sand movements and reefs. How is sand moved by water? How… Read more

Biodiversity Survey

Science Fair Project Idea

Scientific Method

Survey your area to find out which species of plants and animals live there. You might be surprised to find out that something you grew up thinking was very common, is actually quite unique! For example, if you live in the great plains, then you may think that prairie dogs are a nuisance or a pest. Actually, some species of prairie dogs are only found here, and have a very important role for short and tall grass prairie ecosystems. The prairie dogs are an important part of the food-chain, and… Read more

Air Pollution

Science Fair Project Idea

Scientific Method

Smog days are often posted in your local newspaper. Check how many smog days your city has had in the last year. How does it compare to to other years? You can also take pictures of your city landscape on high and low smog days. How do the pictures compare? How does smog in the atmosphere affect visibility? What is smog made of? You can use tongue depressors smeared with Vaseline to check for smog particles in different areas; just stick in the ground and look at them a few days later. … Read more

Home Sweet Biome: How Do Plants Grow in Different Environments?

Science Fair Project Idea

Scientific Method

Have you ever looked around and noticed the plants and animals that grow in your neighborhood? Have you ever visited friends in another part of your city, state, or even another part of the country? Have you noticed whether the plants and animals where they live are similar to those growing near you? What would it be like to live where they do? Why do certain plants and animals grow in one area, but not in another? In this science fair project you will learn about biomes and how different… Read more
