"Giant Kelp Forest" © 2010 Tom Thai Could you describe the kelp forest food web as a system? Your students will design and use a simple model to test cause and effect relationships or interactions concerning the functioning of a marine food web, ranking their hypothetical ecosystems according to their stability when faced with a natural or man-made disturbance.

NGSS Performance Expectations:

5-LS2-1. Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment.
MS-LS2-3. Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
MS-LS2-4. Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
HS-LS2-6. Evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem.

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

Oceanic Circulation: What Keeps the Ocean in Motion?

Why is the ocean vital to our planet? There are many reasons, but one important one is that the ocean is a major player in regulating our weather and climate through currents. In this lesson plan, your students will model ocean currents with cups, water, and food coloring, and explore how temperature and density differences set deep ocean waters in motion to create a global oceanic circulation system.

NGSS Performance Expectations:

MS-ESS2-6. Develop and use a model to describe how unequal heating and rotation of the Earth cause patterns of atmospheric and oceanic circulation that determine regional climates.

Ozone Depletion

Science Fair Project Idea

Scientific Method

The ozone layer is important for blocking most of the harmful radiation that comes from the sun. You can find maps of the ozone layer and compare different regions of the globe for ozone coverage. Where are the problem areas? Is there a difference in ozone coverage between different hemispheres? Between populated and un-populated areas? In atmospheric regions over land masses or over bodies of water? Some scientists think that aerosols in the air are breaking down the ozone layer. You can do… Read more

Recycling Greywater: Can Plants Tolerate It?

Science Fair Project Idea

Scientific Method

One way to conserve water is to find safe ways to use it more than once. Here is a project to test whether greywater (water that has been used for washing or bathing) can be used for watering ornamental plants. Read more

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

Global warming, pollution, and deforestation are just a few examples of how human actions affect our planet. How can we reduce our impact on the environment? In this lesson, students will find out by using an online tool called Your Plan, Your Planet. Based on their findings, students will come up with their own action plans aimed at reducing their personal ecological footprint and assess its effectiveness after implementation. Read more

NGSS Performance Expectations:

MS-ESS3-3. Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment.

Using Daphnia to Monitor Water Toxicity

Science Fair Project Idea

Scientific Method

One way to test for the presence of toxic compounds in a water sample is a bioassay. In a bioassay, a living organism serves as a detector for toxins—the same way canaries were used in coal mines to detect invisible toxic gases. In this project, water fleas (Daphnia magna), a freshwater crustacean, are used in a bioassay to monitor water quality. Many variations of this experiment are possible. Read more

What Do We Do With Our E-waste?

Science Fair Project Idea

Scientific Method

If you made a pile of all the electronic devices (cell phones, computers, stereos, televisions, MP3 players, video game systems, remote-control toys, etc.) that your family has gotten rid of since you were a baby, how big would that pile be? Would it be taller than you? Would it fit better in a wheelbarrow or in a pickup truck? And did they just throw it in the trash? In this science project, you'll explore what people in your community do with electronic waste, commonly called e-waste, and… Read more
