  1. EQ: How can we determine the safety and drinkability of our water supplies? • LT: I can describe the processes that can be used to convert unusable water to usable resources. • LT: I will describe groundwater. I will determine which type of soil is most permeable to water. I will explain why groundwater is becoming a non-renewable resource.

  2. Welcome! Warm Up 3/19/14 • What are three properties of the ocean? • 2. What reasons have people studied the ocean? http://goo.gl/cE3HIG

  3. Intramural Sign up Eligible: NO Bounce No Tardies Reading Plus

  4. LATE WORK in GOGGLE DRIVE • QR CODES AROUND the Room • Do NOT CHANGE THE NAME OF THE ASSIGNMENT TO YOUR NAME • MAKE SURE PDF AND YOUR NAME IS IN THE DOCUMENT

  5. Review • Google "Troubling signs in Paradise"    • http://video.msnbc.msn.com/nightly-news/50152559#50152559 • Explain how the tsunami in Japan has affected other ecosystems. • http://www.NBCnews.com

  7. DEMO: Soil TestingSoil Testing Data Table * Look at the sample at your table for the observation sections

  8. Groundwater Notes 23 Groundwater – water that soaks in the ground & collects in rocky pores (pores – space between rocks) Permeable – allows water to flow easily through (ex: sandstone) Impermeable – Doesn’t allow water to move through b/c of small, few or no pores (ex: clay) Aquifer – layer of permeable rock that lets water move freely

  9. NB 23: Groundwater

  10. How does groundwater travel? NB 23 Interconnecting pores How do you replace groundwater? Time and precipitation Why is groundwater becoming a non-renewable resource? We are using it up faster than nature can replace it. (Avg. person use 397 Liters per day) Also pollution

  11. Finish the conclusion questions for the lab

  12. EXIT: • How did you observe permeability in today’s activity? • Use Impermeable in a sentence

  13. For Teacher Demo: 4 150 ml beakers 1 large beaker (1000ml) or 1 gallon container 3 cups 9 oz tall clear cups with hole in center 3 pieces of filter paper placed in cups Each cups filled about ½ way with sand, clay (powder) or gravel Ended up using the same gravel, sand and clay all day At end of the class just poured out the excess water (Each lab tray had clear cups with samples of clay, sand and gravel, magnifying glass, color pencils)

  14. For Teacher Had class go ahead and make observations on handout • Have 4 student volunteers handle the timing. I had one person pour 100 ml of water into each of the cups. (Stoff used 50 ml) Three other students did the timing. I had the students take the cups to their seats while the water was still dripping . • Told students to let me know when at least 90 ml had poured through • Then went over definitions and picture slide. Came back to the time slide. Had students finish questions 1-3 from lab. Next went over questions slide finishing with them answering all the questions.
