The Carbon Cycle

Objectives:

1. To describe how carbon cycles naturally through living and nonliving parts of an ecosystem.
2. To understand that carbon is essential for living things
3. To understand that burning fossil fuels adds carbon to the cycle and contributes to global warming

Directions: Read The Carbon Cycle sheet and make a list of all the places in which carbon is found on Earth. Then you will play an online interactive game in which you will play the role of a carbon atom. As you play the game take notes so that you can answer the assessment questions that follow.

The link below is provided for you on the Ecology power point.

Post-game questions:

1. How many stops DID you make on your trip?

1. How many stops CAN you make? Will your journey ever end?

1. Is everyone’s journey the same? Why or why not?

“Window to the Universe: The Nitrogen Cycle”

Objectives:

1. To recognize and explain the nitrogen cycle
2. To explain why nitrogen is essential to living things
3. To recognize that the nitrogen cycle is complex and nonlinear traveling between organisms and the physical environment

Directions: Read the page The Nitrogen Cycle and answer the following questions. Please do not write on the article because there is only a classroom set. Please return when done!

1. Where is nitrogen found on Earth?

1. Does it move from place to place or stay still?

1. Why is it important?

Directions for activity:

Nitrogen travels with the help of bacteria, water, lightning, plants and animals. Nitrogen reservoir signs are placed around the room and these are the places to which nitrogen can travel. For this activity you are playing the role of a nitrogen atom. You will travel through the nitrogen cycle (i.e., to different stations around the room) based on rolling dice. You will carry a nitrogen passport and stamp it each time you get to a nitrogen reservoir station. Then toss the die at the reservoir to find out what your next destination will be. Write a note in the passport to indicate how you are getting from one place to another based on what the die says.

Discussion questions (use the article to help with questions d, e and f):

1. How many stops DID you make on your trip?
2. Will your journey ever end?
3. Was everyone’s journey the same? Why not?
4. What would happen if a farmer used too much fertilizer? (In this game, that would mean that everyone started from the fertilizer station at the same time.)

1. What would happen if we burnt too many fossil fuels?

1. Livestock farming creates a large amount of animal waste. How would this affect the nitrogen cycle?

The Phosphorus Cycle

Directions: Study the diagram and describe how phosphorus cycles through the ecosystem. If you need additional help read the section in your textbook titled the phosphorus cycle.

______

How is the phosphorus cycle different from all of the other nutrient cycles?
