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:
  • Grass
  • Weeds
  • Dirt
  • Ants
The first items come to mind quickly. But give it more time. What else is there?
  • Any other insects that can be seen if you watch for several minutes?
  • The roots of the grass or other plants
  • What is below the dirt?
  • What microorganisms are in this environment?
  • How do these plants get water? How much water is in the circle now?
  • What animals or insects are several inches below the grass?
  • What is several feet below the surface?
  • Is there anything hundreds of feet below? Does it affect the environment you are looking at?
  • What's in the air above your circle?
  • What animals come to this plot when you are not there? Does the plant life affect the animal? Does the animal affect the plant life?

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:
  • Living objects
  • Non-living objects
It also includes all
  • Solids, liquids, and gases
Specifically, an environment includes:
  • Plants
  • Animals and insects
  • Microrganisms
  • Air
  • Water and a system for moving water
  • Rocks and geology
  • Temperature and weather
AND the environment also includes:
  • Events that alter that ecosystem.

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:
  • Air Pollution
  • Water Pollution
  • Pollution on Land
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.

This is MatchCard #2 of the Botany Unit Study.
    The 1st page is the student worksheet. They how each of the five factors contributes to alterations in the environment.

    The 2nd page is instructor's key.

    The 3rd page has information pieces for students to cut apart and use on the MatchCard.

How to Use the MatchCards

MatchCard Science Instructor's Guide

MatchCards are a teaching tool and a game-like review system. Students have fun learning information and showing that they remember it. Better yet, as the school year progresses they build on to the information they have retained.

Learn more about using MatchCards by downloading the FREE MatchCard Science Instructor's Guide. You will find ideas for making a notebook to review and master science concepts.
