1. Get to work… 1.Pick up the two handouts from the front table. 2.In your ISN table of contents, fill in pages 48 & 49 as Biogeochemical Cycles. 3.On the top of ISN pages 48 & 49, put Sept 28 and Biogeochemical Cycles. 4.Finish filling in the water cycle diagram you started Friday.

2. Reminders … 1.Cell phones 2.Backpacks, food/drink 3.There are zeroes in the gradebook. Office hours. 4.Unit summative test on Friday !

3. Today … 1.We will fill in the water cycle diagram we started on Friday. 2.We will talk about human impacts on the water cycle. 3.You will research and takes notes on biogeochemical elements.

5. Water Cycle … Precipitation Snow melt Run off Flow

6. Water Cycle … Run off Infiltration Percolation Aquifer

7. Water Cycle … Plant uptake Groundwater flow

8. Water Cycle … Condensation Transpiration Evaporation Run off Transpiration Respiration Perspiration

9. Water Cycle … 1.What parts of the water cycle do humans change?

10. Water Cycle … Precipitation Snow melt Run off Flow Dams change …

11. Water Cycle … Run off Infiltration Percolation Aquifer Paved areas … When aquifers…

12. Water Cycle … Condensation Transpiration Evaporation Run off Transpiration Respiration Perspiration Pollution affects… Cutting down trees …

13. Other cycles… 1.We will learn about biogeochemical cycles later, but we need to know a few things first. 2.Highlight headers. (vast) 3.Do research in the textbook and handout. 4.10 minutes on your own. 5.5 minutes check in with partner. 6.True/False check up. 7.Tape to ISN page 49.

14. True/False… 1.Matter is destroyed and created on a regular basis. 2.Carbon is important to life because it bonds with other elements and other carbons easily. 3.There is a lot of phosphorus in the biosphere. 4.Humans use phosphorus for fertilizer. 5.There is a lot of nitrogen in the atmosphere. 6.Nitrogen cycles out of the atmosphere easily. 7.Plants make their own food. 8.Consumers get their nutrients from other organisms. 9.Decomposers break down music.

15. Paved areas (roads, parking lots) prevent infiltration. This creates unnatural run off or flooding. Cutting down trees prevents some plant uptake and transpiration. This results in unnatural run off and even changes in weather. Dams change water flow. This affects life used to the natural flow. Pollution affects life that lives in the water or depends on the water. When aquifers are drained, the water can’t be easily replaced. This affects our drinking water.
