Live Webcast with NASA September 22, 2011 @ 10:00am ACS and NASA partnered to launch a live webcast on NASAs Digital Learning Network (DLN). Pacific High school was selected along with 2 other schools in the United States to participate in a live webcast, with ACS and NASA scientists (located at Johnson Space Center) who explained and answer questions related to water purification processes, the IYC global water experiment, and water purification on NASAs International Space Station.

Slide 3

Lab Water: No Dirt, No Germs Possibly the biggest chemistry experiment ever.

Slide 4

Purpose To raise awareness of the critical use of chemistry to provide one of the most basic human needs - Safe, Clean Drinking water.

Slide 5

Research This lab will explore the role water has in society and the environment.

Slide 6

Water: No Dirt, No Germs Use household materials to build a water filtration unit and identify the efficiently of different filtration materials

Slide 7

Background By 1911, water treatment was becoming common in Europe and North America.

Slide 8

Waterborne disease In developing countries 4 out of 5 illness are caused by waterborne diseases. 1.1 billion people still lack access to improved drinking water. 2,213,000 deaths annually.

Slide 9

After Tsunami in 2004 and Japan in 2010 and Hurricanes like Katrina, there is always large increase in water bourn diseases such as cholera, Hepatitis A, Typhoid fever, Malaria, and Dengue Fever. Natural Disasters

Slide 10

Waterborne disease Waterborne diseases such as typhoid fever and cholera are still around, killing thousands of people each year, even though chemical technology tools for clean water are available.

Slide 11

Number of cases of waterborne disease

Slide 13

Transmission of disease through water

Slide 14

Eliminating Waterborne Disease With simple household materials, water can be filtered and disinfected to produce clean safe drinking water for the world, virtually eliminating waterborne disease.

Slide 15

Lab No Dirt, No Germs This lab will replicate two main steps of drinking water treatment: 1. Clarification 2. Disinfection

Slide 16

Clarification To remove solid debris from natural or waste water Involves four steps: 1. Aeration 2. Coagulation 3. Sedimentation 4. Filtration

Slide 17

Clarification Step 1: Aeration Aeration: adds air to water Allows gases trapped in water to escape. Adds oxygen to the water

Slide 18

Clarification Step 1: Aeration Done by shaking and pouring water back and forth between two containers

Slide 19

Slide 20

Clarification Step 2: Coagulation Coagulation: removes dirt and other floating solid particles by chemically sticking them together in FLOCS (clumps of Alum and sediment).

Slide 21

Clarification Step 2: Coagulation Done by adding ALUM and stirring for 5 minutes

Slide 22

Slide 23

Clarification Step 3: Sedimentation Sedimentation: gravity pulls particles of FLOC to bottom of container. Clear water remains at top and is drained and filtered.

Slide 24

Clarification Step 3: Sedimentation Done by letting ALUM treated water sit for 20 minutes.

Slide 25

Clarification: Step 4 - Filtration Filtration: sand and pebble filter removes most impurities that remain in the water

Slide 26

Filtration Unit

Slide 27

Clarification: Step 4 - Filtration Done by pouring the top of the untreated water into a filter and collecting the treated water.

Slide 28

Disinfection Disinfection: Drinking water chlorination A small amount of chlorine is added to large volumes of drinking water. Destroys germs (Bacteria & Viruses).

Slide 29

Disinfection Done by adding enough chlorine (bleach) to destroy germs, plus a little more to fight new germs that water may encounter before water reaches your home. Extra chlorine is called chlorine residual

Slide 30

Slide 31

Disinfection Chlorine test strips detect the chlorine residual.
