Ecology Activities

Your Own Backyard

Go outside in your yard or a grassy field. Let your students cut a piece of yarn or string - approximately ten feet long would be fine. They use their string to create a circle on the ground. This is the ecosystem they are going to investigate for a few minutes.

What's in their ecosystem? List their responses: The first items come to mind quickly. But give it more time. What else is there?

Your Miniature Ecosystem

If you did not make a terrarium when studying different types of ecosystems, now is a great time to do so.

You will have your own little ecosystem to watch and nourish.

What parts of the ecosystem do you have control over? What are you not able to control?

What kinds of things would be a risk to your ecosystem?

What Comes, Must Go

Discuss the last time you had a major grocery shopping trip. What kinds of things did you buy? How many bags did you bring into your house?

Before discussing it further, can they quickly list ten items that came from that shopping trip? Better yet, you can save this activity until a time when you lug all the bags into the house. Then have them choose ten items without knowing what will be done next.

Where did it come from?
Think of where those different products came from. What ecosystems did they originate in? Was the environment changed in anyway in the process of getting them to your house?

Where will it go?
Predict what is going to happen to those products. How long will they be in your house? Where will they go afterwards? Does that have any impact on the environmnet?

Make a poster showing where those (or other) items come from and where the final materials go.

What Is An Environment?

The environment is everything in an ecosystem that interacts with all the other elements. It includes: It also includes all Specifically, an environment includes: AND the environment also includes:

Factors that Alter Ecosystems


forest fire

Fire is bad, right?

Well, much of the time it is. Especially if it is your house that catches on fire. No person or animal wants to see their home burnt down.

Fires can be manmade or natural. Lightening produces fires at times. While it is often detrimental, sometimes natural fires are beneficial. For instance, it can burn trees that might encroach on grasslands and eliminate that particular ecosystem with its unique wildlife.

But a downside of fire is that plant and animal communities are quickly destroyed. Fires may get out of control and threaten animal and human life as well as their habitats.


farm fertilizer

Fertilizer is good, isn't it? Of course, we want plants to grow for food for animals and humans.

Fertilizer is used to make soil richer in minerals in order to grow more plants. The problem is that it may drain from the soil into streams after a rain. Then the mineral rich environment causes algae to grow on top of the water. Due to the additional algae, sunlight may not reach the plants and fish at the bottom of the stream.

Acid Rain

Sulfur and nitrogen from factories change the water in the clouds over cities. As the acid rain falls, stone and brick buildings are damaged with time.

Soil also becomes more acidic making it harder for plants to grow.

Greenhouse Effect


Carbon dioxide acts like a blanket and traps the sun's heat in the earth's atmosphere. This may increase the temperature of the earth and change the climate in parts of the planet.

The greenhouse effect is increased by burning fossil fuels which release carbon dioxide into the air.



Pollution is the negative effect of humans on nature. There are different types of pollution: Thankfully, much pollution can be avoided or reversed by making good decisions. Recycling materials reduces land pollution by decreasing the amount of garbage in landfills. Re-using the materials may require less factory output as well.

Ecology Science Experiments

Algae and Fertilizer

What concentration of fertilizer will affect the growth of algae?

For this experiment, you need to obtain four different samples of the same species of algae. You may obtain it from a local pond, aquarium store, or on-line science supplier.

You will need four different glass containers the same size and shape. Have different amounts of fertilizer in each container (one should have no fertilizer.)

Record the growth of the algae over three weeks. Take pictures to document the differences.

If you hold the glass up and shine a light through the top, is there a difference in the amount of light that penetrates?

Acid Rain and Plant Growth

If you use a mild acid (like vinegar) to alter the pH of the water, will it affect plant growth?

You will need cuttings of plants like a strawberry plant or philodendron that will sprout roots in water. You will also need pH paper to analyze the pH the water the cuttings are in.

Have three or four different containers, and add different amounts of vinegar to decrease the pH. Analyze the difference in the amount of new roots grown and the pH of the water.

How To Use MatchCards


MatchCards make science concepts and corresponding vocabulary interactive. As students move the information pieces on the MatchCards they review the material they have already learned.
