1. Warm-up:  Open the Environmental Science Book to page 12 and read “Spaceship Earth”.

2. How is Planet Earth a system? Is it a complete system? Is the earth an open or a closed system?

3. DEEP SPACE 3000  Listen for instructions  3000 years  1000 member crew  On a spaceship that is orbiting the sun  Big windows  As large as physically possible  No items in or out  Nothing from outside except solar energy  Only use today’s technology  Brainstorm First: List material & nonmaterial needs before drawing.

4. What To Do:  Draw a picture of your spaceship.  List the contents of each compartment.  Show how the contents relate to each other. (A common theme in environmental science: Everything is related!)  List your outputs for each compartment (like we did in class) and show how they become the inputs for other compartments. For example, feces from the barnyard animals can be used to fertilize the greenhouse plants which are being grown for fruits and vegetables.

5. Prepare a Report on Your Spaceship (oral or written):  Identify the essential needs to sustain life on the spaceship.  How did you design the ship to meet those needs?  What issues might you encounter in the future (population growth, education, old age, etc.)?

6. You can assume…….  NASA engineers have developed an onboard energy and propulsion system that will provide travel, lights, heating and cooling.  Artificial gravity  Protection from harmful radiation

7. Cardinal Rules:  Nothing goes in  Nothing goes out  Every input must come from an output.

8. Exit Ticket  Which 1 ship would you want to call home?  List two ways the earth is different from a spaceship.  List three characteristics of the earth that let you know it is a closed system.
