of MATTER and ENERGY
3. OPEN SYSTEM CLOSED SYSTEM
•Energy and matter are •Energy but NOT
exchanged with matter is exchanged
surroundings. with surroundings
•Example: Lake •Example: Closed
Michigan….How is Aquarium…How is this
energy and matter different from the Lake

5. • Read the material provided…Find out what
each sphere is and write it in the appropriate
place in your notes
• FINAL QUESTIONS: Are each of the 4 spheres
open or closed systems? Why? Is the entire
Earth System open or closed? Why?
6. ASSIGNMENT:
Foldable for the 4 “spheres”
Geosphere-Hydrosphere-Atmosphere-Biosphere
• Requirements are as follows…
– On the cover-Title, 4 labeled flaps (one for each of the “spheres”) and
Decoration/Illustrations
– Inside: - On the flipside of each corresponding “sphere” write and
illustrate what it is.
– Underneath the flaps, describe and show how each of the spheres
interacts or affects one of the other spheres. For example, the smoke
from a forest fire in the biosphere will end up affecting the
atmosphere. Winds will carry ash and smoke to other parts of the
world.
• Foldable should also be neat, have color, and be the result of effort.
