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 make observations about rock type vs. permeability • I will draw and label the steps for water filtration • I will work with my group to review water filtration concepts. • Warm Up • Intro to Water Filtration • Build Water Filter
Welcome! Warm Up 3/20/14 • 1. Why would clay be found at the bottom of a well? • 2. Why are we running out of groundwater? http://goo.gl/cE3HIG
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
B. Sandstone C.Limestone A. Shale Which rock type is least permeable?
B. Sandstone C.Limestone A. Shale Which rock type would I found in an Aquifer?

How long can an aquifer last?http://www.classzone.com/books/ml_science_share/vis_sim/ewm05_pg39_aquifer/ewm05_pg39_aquifer.html
Demo: What happens when an aquifer runs dry? • Show a moist sponge vs. a completely dry sponge
Finish up • Finish the conclusion questions for the lab • Submit on Google Drive QRCODE • How did you observe permeability in today’s activity? • Use Impermeable in a sentence

Water Filtration Vocabulary 24 • Runoff – is precipitation that flows over land into streams and rivers. This water later enters oceans. • Filtration – process of passing water through a series of screens that allow water through but not large particles • Aeration – The water is mixed toreleasedissolved gases and to suspended particles in water column. • Coagulation – The process by which particles in a liquid clump together • Sedimentation– The water left undisturbed to allow the heavy clumps of particles and coagulants to settle out • Disinfection – The water is treated to destroy any remaining disease causing pathogens • Potable Water – water safe enough to drink by humans
