35.Water FiltrationEQ: 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.POU: 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.
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?
Go to www.goo.gl/
vta7d1 to record your
response
A. Shale B. SandstoneC.Limestone
Which rock type is least permeable?
A. Shale B. SandstoneC.Limestone
Which rock type would I find in an Aquifer?
Well Simulation http://www.classzone.com/books/earth_science/terc/content/investigations/es1401/es1401page02.cfm?chapter_no=investigationA well Simulation for the different types of rocks
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?
Compare a moist sponge to a completely dry sponge
Finish up – 10 minutes1. Finish the
conclusion questions for the lab
2. Tape into your Notebook on page 23
3. Work on uploading any missing assingments to your google drive folder
Water Treatment Video
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 to liberate dissolved 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 – drinkable water Safe water: water that will not harm you if you come in contact with
it.

BANKYou will work in your lab groups to answer
questions. When I call time, flash me your Ipad with only
the Letter of the answer choiceSome questions you will be silent (No Help
from your group!)Some I will let you come to a consensus
