https://www.youtube.com/watch?v=evH2r5dOq5Q (2:47) The Water Cycle Rap

(w/ lyrics)

The water cycle is

taught in multiple

grades. Here is a

refreshing rap to

review. Before

diving into runoff.

Demo 1: Fresh Water Materials: Empty gallon containerShot glass or small clear measuring cup A little over one ounce of a colorful liquid (soda or water with food dye)Eyedropper or Petri dishA selection of empty containers or glasses, for example: Half-gallon container Two-liter soda bottleQuart container One-liter soda bottlePint-sized container or pint glassSmall, empty glass

Procedure:

1. Line up the containers—except the eyedropper or Petri dish—from large to small so all students can see2. Explain that if the gallon represented all the water on earth, how much of it is fresh water for people to use?3. The students who selected the shot glass are correct—sort of.4. Remove about 1/3 or roughly 1 teaspoon of water in the shot glass by using an eyedropper or pouring it into the Petri dish. The water that remains in the shot glass represents fresh water that cannot be accessed—it’s too deep in the ground or it’s frozen. The liquid in the eyedropper or Petri dish represents fresh, accessible water that humans can use. Compare it tothe volume of a gallon.

•Water may seem abundant, but drinkable water is rare

• Freshwater = relatively pure, with few dissolved salts

–Only 25% of Earth’s water is fresh

–Most freshwater is tied up in glaciers and ice caps

6

*

*Where is that fresh water?

*20% Great Lakes of North America

*20% Lake Baikal in Russia

*60% in the rest of lake, rivers,

groundwater and soil

Faith the Fish

An Adventure Down

Stream

Faith the fish started life in a clean fresh water river. The river meanders through a protected wilderness area. She has lived in this stretch of the river all of her life. Now she is going on an adventure – traveling downstream.

I need 9 volunteers to lead Faith down stream.

I need 8 volunteers to contribute to the stream. (It is all scripted, just follow

instructions)

Everyone draw out a data table:

1. Record observations and data as she swims.

2. Then discuss as a large group

*The result of polluted

storm water, or “Urban Stew,” entering streams and the Mississippi River can cause damage to ecosystems. When the streams are polluted, plants, aquatic insects, birds and other animals that depend on the streams for survival, suffer.

Ultimately, humans also suffer. Streams and rivers provide urban wilderness areas, and they are used for recreation, agriculture and drinking water. It is only with pollution prevention efforts by local citizens that waterways will remain clean and safe.

* Types of Pollution:

* Nutrient pollution from agriculture and industry

* Pathogens and waterborne diseases

* Hazardous waste

* Bug spray, nail polish, oil paints, furniture polish

* Toxic chemicals from natural and synthetic sources

* Pesticides, petroleum products, synthetic chemicals

* Arsenic, lead, mercury, acid rain, acid drainage from mines

* Sediment

* Clear-cutting, mining, poor cultivation practices

* Thermal pollution (what’s this?)

* Downspouts direct water to lawn

* Rain Barrels to capture water from the roof

* Trees catch rain and filter it

* Prairie plants have deep roots to slow water runoff and filter water

* Rain gardens capture runoff from driveways

* Pavers instead of cement

allow water to seep through

to soil

*Green Roofs capture and

use water while insulating

and dampening noise

* Re-grading slope of land for

slow runoff and increased

infiltration

Be a storm water hero. Stop rain where it drops.

Have students generate ideas in a discussion before explaining them.

**1. Using your adjectives and creativity to draw cartoons

depicting Faith’s adventure.

*2. Devise an educational activity to teach others about storm

water pollution and its prevention.

*3. Write a contrast story describing what it would be like to

be a fish living in a clean stream vs. a polluted stream.

*4. Make fish dioramas, yes the old fashioned kind can be fun

– using paper plates or shoe boxes, etc.

*5. Use picture books on the topic of water pollution,

conservation, aquatic habitat, etc.

*6. Visit a nearby pond and do a pond study, collect data:

temp. D.O., pH, turbidity, use field guides to identify

organisms.

*7. Paint river or pond ecosystems19

*

*Explain chemically why water picks up so many pollutants? Draw molecular bonding.

*Create a model depicting on the molecular level why in winter ponds do not freeze from the bottom up.

*Explain why some pollutants won’t dissolve in water.

*Soaps can have phosphates in them. Why are phosphates harmful to streams or lakes?

*Write a story explaining how phosphates can lead to a dead zone in waterways.

*Research social justice issues regarding access to clean drinking water.

b. (1 group sit down)

c. By 2025 ½ of the countries worldwide will face water stress or shortages

d. (2 more groups sit down)

e. How many groups do you think will have clean water by 2050?

f. (1 ½ groups sit down)

g. In 2050, if the water crisis continues as it is going 75% of the world’s population will not have access to clean usable water and will be affected by water scarcity.

h. Write down how when/if 75% of humans are deprived of the water they need will this affect you.

Millions Lack Safe Drinking Water

22

Areas where water use exceeds supply

23

*

• 1.1 billion people live without clean

drinking water

• 2.6 billion people lack adequate

sanitation

– (2002, UNICEF/WHO JMP 2004)

• 1.8 million people die every year from

diarrheal diseases.

• 3 900 children die every day from water

borne diseases

– (World Health Organization)

• Solutions:

• Treat sewage

• Disinfect drinking water

• Public education to encourage

personal hygiene

• Government enforcement of

regulations

*

*“National Geographic reported in Sept.

2002 that bone-dry Dubai had 2.6 million

gallons of expensively desalinated seawater

coursing through its popular Wild Wadi

Water Park.”

*“Time Magazine reported in April 2004 that

the 2.5 billion gallons of water used to

irrigate the world’s golf courses each day

would be enough to support 4.7 billion

people at the U.N.’s daily minimum of

water.”* CHEM In Your World Ed 1 Joesten and Hogg p. 208

Botswana• How a culture treats water shows

how it is valued. For example, the importance of water can be seen in the flag of the Republic of Botswana (a landlocked country south of the equator in Africa.) The blue represents water - the motto on the Botswana national arms is PULA, meaning "let there be rain." The word for water in Setswana is PULA the word for money in Setswana is PULA. The black and white stripes symbolize the racial harmony of the country's people, as well as the pluralist nature of their society. The stripes were inspired by the national animal of Botswana, the zebra. (Pronounced zebra not zeebra)
