1. Biogeochemical cycles
EQ: How does the movement of matter and energy through biological systems impact you?

2. Cycles of Matter
Unlike the one-way flow of energy, matter is recycled within and between ecosystems. - water and carbon cycle

3. What is the Water Cycle?
continuous process by which water moves from Earth’s surface (ground) to the atmosphere and back to the Earth’s surface

4. Water cycle Water enters the atmosphere through: Evaporation
Transpiration

5. Water cycle Water leaves the atmosphere through: Condensation
Precipitation

6. Processes of the Water Cycle
The Sun heats up the water in Earth’s oceans and lakes.

7. Processes of the Water Cycle
1. Evaporation: liquid water changes to a gas called water vapor.

8. Processes of the Water Cycle
2. Transpiration: water vapor is released by plants.

9. Processes of the Water Cycle
3. Condensation: Water vapor in the air gets cold and changes back into liquid, forming clouds. 

10. Processes of the Water Cycle
4. Precipitation:
Water vapor condenses and heavy droplets fall as rain, snow, sleet, or hail

11. The precipitation that falls on the land will soak into the soil and become groundwater or run off the land, eventually flowing back into the ocean to occur again.

12. The Carbon Cycle
carbon is present in the atmosphere as carbon dioxide (CO2)
This carbon dioxide came from
Feeding
Cellular Respiration
Burning of fossil fuels
Decomposition of organic matter

13. CARBON CYCLE SUMMARY: 1. Consumers take in carbon when they eat.
2. Consumers release carbon into the atmosphere during cell respiration.
3. Producers take in carbon during photosynthesis.
4. Decomposers release carbon into the soil through decomposition.
5. Humans release CO2 in the atmosphere when burning fossil fuels.

15. Carbon Cycle Game First round- notes Second round- no notes
Students are in groups of 4
1 game board and the cards are face down in a pile
Draw a card and try to place it on the board
If the student can play the card correctly, they place it on the board
If not sure, you can hold onto the card and play it at any point in the game
Points:
2 pts- play the card correctly when it is drawn
1 pt- plays the card correctly after holding it
-3 pts- plays card incorrectly
First round- notes
Second round- no notes

20. Question 4
Water continuously moves through the water cycle between land, oceans, and the atmosphere. When water evaporates from a puddle on the street, what happens to the water molecules? A. It is in the air as an invisible gas. B. It disappears and no longer exists. C. It immediately moves up to the clouds. D. It breaks up into hydrogen and oxygen atoms.

21. Question 5

From the atmosphere to the trees
