Teaching Point: “To analyze water infiltration and its connection to soil saturation.”
Do now Group Discussion: Compare and contrast these soil layers in as many ways as you can.
Infiltration is the movement of water through soil or fractured rock.
TP: “To analyze water infiltration and its connection to soil saturation.”
Water in the Ground
The water table is the boundary between unsaturated and saturated soil in the ground.
Underground Boundary for Water
TP: “To analyze water infiltration and its connection to soil saturation.”
The zone of aeration is the unsaturated soil or rock above the water table
The zone of saturation is the saturated soil or rock below the water table
Zones Near the Water Table
TP: “To analyze water infiltration and its connection to soil saturation.”
Task- Question: How might the red house’s groundwater well no longer be able to draw up water?
Underground Boundary for Water
TP: “To analyze water infiltration and its connection to soil saturation.”
Factors controlling the water table:
The Water Table Rises and Falls
TP: “To analyze water infiltration and its connection to soil saturation.”
Seasonal Fluctuations in Water
TP: “To analyze water infiltration and its connection to soil saturation.”
Task- Think/Pair/Share: Which parts of the water cycle might lead to the rise of the water table in the winter and fall in the summer?
Cities Draw from Aquifers
TP: “To analyze water infiltration and its connection to soil saturation.”
Aquifers are groundwater locations used by cities or local towns to draw drinking water from.
Task- Discussion: How could this town begin to stop the intrusion of salt water into their fresh water supply?

Task: Using what we just learned about saturated soil and infiltration…
Student 1- make connections between water infiltration, soil saturation and the water cycle
Student 2- create an illustration showing how the water table can go up and down depending on how much precipitation falls
Student 3- create a thinking map showing how infiltration and soil saturation might be connected
Class Activity- Soil Saturation
TP: “To analyze water infiltration and its connection to soil saturation.”
Let’s Review in Groups
In your group, go back into your notes and make a list of the three (3) most important concepts we learned today. Place those the three in order from the most important concept to least important.
