Presentation Transcript

  1. Science Starter • Take the green paper at the door. • Supplies Needed: • Clipboard • Pen or Pencil • Purple Vocabulary Sheet

  2. Watershed stations and vocabulary review: • Stations 1-9 will be answered on the green paper. • Station 10—Making a watershed • Station 11—Vocabulary Review with Flashcards • Station 12—Succession Review (at completion of all other stations) • Rotate at your own pace • Only 3 people per station maximum • Green paper is due at the end of class!

  3. Water Cycle- Fill in your diagram Step 1- Sun heats water.

  4. Water Cycle- Fill in your diagram Step 2- Water evaporates as water vapor into the atmosphere.

  5. Water Cycle- Fill in your diagram Step 3- Water condensates into clouds.

  6. Water Cycle- Fill in your diagram Step 4- Clouds release water as precipitation- rain, snow, hail

  7. Water Cycle- Fill in your diagram Step 5- Water runs along the ground or soaks into the soil

  8. What is a watershed? • All the water underground and above ground that flows into the same place (river, lake) • Can be large, or small

  9. What is a watershed? • 2,110 watersheds in the US • Also called a drainage basin

  10. What is surface water? • All surface water drains into a major body of water- lake or river • Eventually most water flows into the ocean

  11. What is a runoff? • Water enters the watershed through precipitation • Most precipitation falls on land and becomes runoff • Runoff is water that does not soak into the soil but “runs” into lakes, river, etc

  12. What is groundwater? • Water that does soak into the soil is called ground water. • As water soaks into the ground it passes through layers of porous rock.

  13. What is groundwater? • Rock that is porous allows water to flow through it. • Soil can have different levels of porousness. • This flow of water through the soil is called percolation.

  14. What is percolation? • Some soil allows a lot of water to flow through and some does not let hardly any • Water sinks down until it reaches a layer of rock or clay that it cannot pass through

  15. What is percolation? • Water that collects on top of that layer is called groundwater. • The layer of rock that is saturated (filled) with water is called an aquifer.

  16. What is the water table? • The very top of an aquifer is called the water table. • The water table can be on the surface, close to the surface or hundreds of feet down.

  17. What is a watershed divide? • Surface water is divided by watershed divides. • A watershed divide is a high point on the land that divides one watershed from another. • Rivers are divided into tributaries- smaller streams that connect off the larger river.

  18. Watershed- Fill in your diagram • Step 1- Precipitation adds water

  19. Watershed- Fill in your diagram • Step 2- Water runs down the watershed divide.

  20. Watershed- Fill in your diagram • Step 3- Water runs into tributaries.

  21. Watershed- Fill in your diagram • Step 4- Water soaks into the ground- called percolation.

  22. Watershed- Fill in your diagram • Step 5- Water settles into as groundwater in an aquifer.

  23. Notes & Diagrams - Tape or glue the notes and diagrams to the RIGHT side of your notebook!

  24. Watershed Worksheet 1- Read the information. 2- Answer the questions. 3- Label the diagram. 4- Draw the well. 5- Turn in completed work. THIS IS DUE AT THE BELL!
