1 34.Ground Water 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 3/18/14 1. What are three properties of the ocean? 2. 2. What reasons have people studied the ocean? Go to goo.gl/vta7d1 to record your response

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

4 Table of Contents 1 Title Assignment Water Properties Webquest 8 Water Cycle Brainpop9 Water Cycle Vocabulary10 Water on Earth Notes11 River Basin Notes 12 River Basin Vocab13 River Basin Scavenger Hunt14 Estuaries Notes 15 Wetlands16 Diagram River Basin to Estuary17 Wetlands and Estuaries Vocab 18 Estuary Ecosystems 19 Ocean Food Webs20 Ocean Properties 21 Ocean Zones and Layers 22 Groundwater Notes and Soil Testing (Handout) 23

5 DEMO: Soil Testing Soil Testing Data Table MaterialsTime for Water to Stop Dripping Sand Clay Gravel * Look at the sample at your table for the observation sections

6 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

7 NB 23: Groundwater

8 How does groundwater travel? 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 NB 23

9 Finish the conclusion questions for the lab

10 EXIT: I. How did you observe permeability in today’s activity? II. Use Impermeable in a sentence
