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?

Demo: What happens when an aquifer runs dry?

Compare a moist sponge to a completely dry sponge

Finish up – 10 minutes

1. 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.
