1. Unit 5: Cycling of Matter and Energy
What topics do you think will be included in this unit?

2. Biogeochemical Cycles
Bio – living organisms
Geo – geological processes
Chemical – chemical processes
*A pathway in which chemical substances move through the living and non-living parts of the earth.

3. Nutrient
A chemical substance that an organism must obtain from its environment to sustain life and to undergo life processes
Examples: carbon, nitrogen, hydrogen & oxygen

4. Can you think of any Biogeochemical Cycles?

5. Topic #1: Cycling of Water How does water move through the water cycle?

6. Water “cycles” through the environment
The hydrologic (water) cycle is the continuous path of water on Earth.
On a white board, draw the water cycle using the correct terms

7. Water Cycle Simulation
Imagine you are a drop of water on your journey through the water cycle…

8. Conclusion:
The water cycle is continuous, but not a step by step process.
