1 What do you know about groundwater? SWBAT describe an aquifer and explain how water moves through the soil.

2 Water Underground Not all surface water ends up in lakes and ponds. Much of the water soaks into the soil, but where exactly does it go? Even though many communities use reservoirs, man-made lakes that provide water, there is still a large population of people that rely on underground wells. Today, we will look at how aquifers, or underground sediment that holds water, form.

3 Here is a close-up drawing of soil. What are pores?

4 Soil is composed of different sized particles. The composition of soil has an effect on the amount of water it can hold.

5 Watch the simulation and consider what the terms permeable & impermeable mean. Discuss with your partner: From a farmer’s standpoint, why would clay be the worst type of soil for farming?

6 TEXTBOOK Use the picture & information on page 626 to define the terms: saturated zone, unsaturated zone, water table.

7 Describe how you would collect water from an aquifer. Be sure to include vocabulary that identifies which layers are present.

8 How are wells replenished with water? Any water that enters the aquifer from the surface is call RECHARGE. Discuss with your partner: What makes the water table rise and fall?

9 How is an artesian well different from other wells? quifers.htm

10 Use the textbook page 627 or the link below to describe/define a spring.
