Eleventh Grade, Environmental Science Science Experiments (Page 4)

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

Here Today, Gone Tomorrow: Saving Migratory Animals

Science Fair Project Idea

Scientific Method

Extinct might be a word you associate with animals that lived long ago, like the dinosaurs, but did you know that over 18,000 species are classified as "threatened" (susceptible to extinction) today? Scientists involved in wildlife conservation have a tough job; they are in charge of determining what needs to be done to prevent a species from becoming extinct. Habitat, food supply, and impacts of local human populations are just a few of the factors these scientists take into account. It is a… Read more

How Does Soil Affect the pH of Water?

Science Fair Project Idea

Scientific Method

Did you know that soils can be alkaline, neutral, or acidic? Most plants grow best in soil near neutral pH, but some plants prefer slightly acidic and others slightly alkaline soil. What is the pH of the soil in your garden? What happens to the pH of water that comes in contact with soil? In this science project you will get to find out. Read more

How Does Soil Change with Depth?

Science Fair Project Idea

Scientific Method

What covers less than 10% of the Earth's surface, yet is a vital natural resource for terrestrial life? What filters ground water and supports most of our food production, not to mention the production of building materials and paper? The answer, often overlooked, is: soil. With this project you can get all the dirt on soil formation, soil horizons, and the composition of different soils. Read more

How Long Does Trash Last?

Science Fair Project Idea

Scientific Method

Even though many cities have recycling programs, a lot of trash still ends up in the dump. Find out which materials will break down and which materials won't. Will the results of this experiment change which products you often buy? Read more

Invasive Species

Science Fair Project Idea

Scientific Method

Invasive species are organisms (either plant or animal) that have been introduced into a new, non-native area and spread rapidly in the new environment due to a lack of regulation by predators. Frequently, invasive species will out-compete native species for resources which can put native species at risk. This is an especially big problem for threatened habitat and endangered species, which are already at risk. Survey your area to document cases of invasive species invading a local… Read more

Macroinvertebrates as Indicators of Pollution

Science Fair Project Idea

Scientific Method

In this science project, you will collect macroinvertebrate samples from multiple points along a body of water, ideally a small creek or stream, and test the pollution burden and biodiversity of small organisms or insects to see if pollution impacts biodiversity. Read more

Maybe you have grown vegetables or flowers, but have you ever grown the flowerpot? Yes, you read that right! In this activity, you will use mushroom roots to grow a biodegradable material that can be molded into a product of your liking, like a flowerpot! Growing a set of bowls, a lampshade, or a pot is easier than you might think. Once you try it out, you just might feel inspired to replace some of your plastic objects with ecological counterparts that you created from mushroom roots! Read more

Measuring Soil Erosion

Science Fair Project Idea

Scientific Method

When you think of environmental challenges facing the world, the first things that come to mind might be global warming, or loss of biodiversity, since these are often in the newspapers. A serious problem that you may not have heard about is soil erosion. Why is soil so important? What is the danger of erosion? How can we measure soil erosion? What can be done to prevent it? Check out this project and you can start finding answers. Read more

Modeling Your Local Watershed and Nutrient Pollution

Science Fair Project Idea

Scientific Method

Have you ever been unable to swim in a body of water because it was polluted? Have you ever wondered where the water came from, or what contributed to its pollution? In this science project, you'll learn how water drains to common areas to create bodies of water and how the land surrounding a waterway can contribute to its health and pollution. Read more
