1
Labelling
WATER CYCLE: Read each process and label the diagram with the correct description.
Water droplets merge & fall from clouds
Water flows downhill to a stream/lake
Water seeps through spaces in soil
Water vapor cools and liquifies
Liquid water is heated, becomes steam
Evaporation from leaves
2
Open Ended
Based on your knowledge about desalination, how would you build a DIY device to get drinkable water at a desert island?
3
Labelling
WATER CYCLE: Read each process and label the diagram with the correct term.
Precipitation
Condensation
Transpiration
Runoff
Evaporation
Infiltration
4
Multiple Select
What are the 3 characteristics of places that suffer the most with water stress?
(more than 1 is correct)
Small population
Overpopulation
Extensive farming (irrigation for crops, and animals)
Arid/dry
Rainy
5
Hotspot
Which area(s) on this map suffer from high / extremely high water stress mainly due to overpopulation?
6
Match
Match the following standards for water quality / impaired waters
Coliform Bacteria
Heavy Metals
Nutrient Pollution
Oxygen-Depleting Pollution (lack of O2)
Persistent Organic Pollutants (POPs)
Bacteria from human sewage & manure
Neurotoxins from mining & fertilizers
N & P -> promote algae overgrowth
Organic matter consumed by decomposers
Chemicals that do not break down

Observe the steps of eutrophication below (from 1 to 9). Notice that once organisms start to die and decompose (starting at #6), this part of the process becomes a cycle (it keeps repeating over and over) until all life is gone. Also notice that once the plants die, they will not perform photosynthesis, which means there will be no oxygen production.
Eutrophication

Labelling
Now you try to order the steps in eutrophication.
Animals die
Algae overgrowth
Fertilizer in runoff
Plants can't do photosynthesis
Fertilizer leaching from the ground
Plants die
Decomposition
Algae dies
Algae blocks sunlight
O2 depletion
9
Steadily delivers water directly to the roots -- avoids water waste.
Drip Irrigation
Slows runoff & erosion, and increase infiltration (helps from groundwater reserves)
Contour plowing
Prevent leaks and block evaporation -- avoids water waste.
Lining irrigation canals
10
Open Ended
Why is there more focus on water conservation for agricultural practices than any other type of human activity?
11
Reorder
Reorder the following steps in wastewater treatment
Physical / Mechanical treatment (screening)
Physical treatment: Primary clarification (sedimentation)
Biological treatment (bacteria degrades organic compounds)
Physical treatment: Secondary clarification (sedimentation)
Treated water goes back to the river
12
Categorize
filtration
screening
sedimentation
degradation by bacteria
coagulation
disinfection
Organize these options into the right categories of water treatment
WATER CYCLE: Read each process and label the diagram with the correct description.
Evaporation from leaves
Liquid water is heated, becomes steam
Water vapor cools and liquifies
Water flows downhill to a stream/lake
Water droplets merge & fall from clouds
Water seeps through spaces in soil
