6. Make your own Watershed Make your own Watershed 1.Take out a sheet of paper, ball it up and smooth it out 2 times. 2.Use blue water based maker to color the tips of the peaks – The Divides 3. You are about to make it rain. What do you think will happen? 4. Lightly spray the paper 5. Where did the water collect, why? This is your lake. 6. The path the water took to the lake is a stream. 7.

7. Watersheds 173a

8. What is a watershed? 173b What is a watershed? 173b o The land area that supplies water to a river system o Also called a drainage basin WATERSHED

9. What is a river? 173c o A large stream RIVER

10. What is a stream? 173d What is a stream? 173d o A channel through which water is continuously flowing downhill STREAM

11. What is a tributary? 173e o A stream/river that flows or contributes water into a larger river The stream is a tributary to the river. Tributary STREAM RIVER

12. Bell work: Block 1 & 2 1. What is another name for a drainage basin? 2. Which layer of the atmosphere contains all weather? 3. Silicon has an atomic number of 14 and an atomic mass of 28.0, how many electrons does it have?

14. What is a Riparian Zone? 173f What is a Riparian Zone? 173f o Filters out pollution before it gets to the water- ocean

15. What is a wetland? 174 o Absorbs water from floods o Filters water going into the river or stream o Habitat for animals and plants RIPARIAN ZONE

16. What is a Fertilizer? 175 What is a Fertilizer? 175 o Increases the growth of algae. The algae uses up all the oxygen and blocks the sun to other plants and animals.

17. Why are pH levels important? 176 o Factories dump chemicals into the water which changes the pH levels. Too high or too low pH levels kills life.

18. What is an estuary? 177a What is an estuary? 177a o A coastal inlet or bay where fresh water mixes with salty ocean water o Estuaries contain brackish water – partly fresh and partly salty water ESTUARY

19. What is a divide? 177b o A ridge of land that separates one watershed from another DIVIDE

30. Is there another place water in Virginia can go? Rivers in Virginia and 30 other states drain into The Gulf of Mexico. That’s about 33 major Rivers. Gulf of Mexico USA Canada Mexico 183

31. Bell Work: Monday 1. What is the northern most state that has a river in the Chesapeake Bay watershed? 2. Rivers in southern VA drain to what watershed? 3. How many atoms are on 1 side of this equation: CH 4 + 2O 2 CO 2 + 2H 2 O

32. Bell work Tuesday 1. 44% of our rivers in VA drain where? 2. What are divides? 3. Name 3 abiotic factors in an ecosystem.

33. Where can airborne pollutants come from? Air over our region comes from various areas that change each day. Most of the air comes from the Midwest and is polluted from power plants and vehicles this doubles the pollution in our area. Pollutants are washed out of the air by rain and goes into the Chesapeake Bay and its Tributaries. 183

34. What is a ecosystem made up of? An ecosystem is made up of the living community and the non-living factors that affect it. The health of an ecosystem is directly related to water quality.

35. What abiotic factors affect an ecosystem? Abiotic factors determine ecosystem type, its distribution of plants and animals as well as the usage of land by people. Abiotic factors include water supply, topography, landforms, geology, soils, sunlight, and air quality/O2 availability. Abiotic factors determine ecosystem type, its distribution of plants and animals as well as the usage of land by people. Abiotic factors include water supply, topography, landforms, geology, soils, sunlight, and air quality/O2 availability. 184

36. What human factors can alter the abiotic factors in an ecosystem? Human activities can alter abiotic components and thus accelerate or decelerate natural processes. For example, people can affect the rate of erosion (a natural process). Plowing cropland can cause erosion, while planting trees can prevent it. Flood protection/wetland loss is another example.

37. What is water quality monitoring? Water quality monitoring is the collection of water samples to analyze chemical and/or biological parameters. Simple parameters include pH, temperature, salinity, dissolved oxygen, turbidity, and the presence of macro-invertebrate organisms.

38. What are found in healthy and unhealthy water systems? Healthy Systems: 1.Clear water 2.Algae levels balanced 3.Adequate oxygen 4.Abundant finfish 5.Aquatic plants flourish 6.Bottom habitats are healthy Unhealthy Systems: Nutrients feed algae Blooms which decreases oxygen and water clarity. So plants cannot grow, animal life is stressed and Decreased so the food chain is broken and human health concerns begin 186
