Properties of Water
Warm Up: The answers are in last classes
notes on properties of water.
1. Describes the tendency of water
molecules to stick to other water
molecules.
2. Why is water called the universal
solvent?
3. What causes the uneven heating
and cooling of the earth?
4. Draw and label the charges of the
ends of a water molecule. (label the
positive and negative ends)
Homework: Study for Properties of Water quiz
(next class)
pH and all of the properties of water

1. You find a piece of metal with a specific
heat of .65 J/g ⁰C. Identify the metal.
2. Coolants keep warm materials cool.
Explain why water might be used as
coolant?
3. Describe the relationship between
density, buoyancy and the ability of an
object to float or sink.
4. Ice floats in water. Why is solid water
less dense than liquid water?
5. Why is polarity such an important factor
in the properties of water?

Parts of a River Basin Vocabulary
Activity: Where Oh Where does my Water Flow?
Divide: Boundary that marks the outermost limit of a
watershed. It is the boundary between one river basin and
another river basin.
Headwaters: Also called the source. It is the beginning of the
river. The headwaters are often located in mountains.
Watershed/River Basin/ Drainage Basin: The tract of land that
supplies water to a river system. People’s actions within a
watershed can affect the overall quality of its rivers.
Tributary: A smaller stream or river that joins a larger stream
or main river
Main Channel/Main River: The main river channel is the
primary channel and course of a river
Infiltration
Homework:
1. Summarize a River Basin in a flow chart or para.
2. Study for Distribution of Water, Water Cycle, and
River Basin Quiz
3. Review pages 16C – 22C

Floodplain: The floodplain is relatively flat land through which
a river flows, which may flood during heavy rain. The soil here
is usually very rich and good for growing food.
Mouth: The mouth is the place where a river flows into a
Aquifer
larger body of water, such as another river, a lake or an ocean

Crumple the white paper. Unfold the white paper. Do NOT flatten the paper. The
paper should have ridges and valleys created by the crumpling process.
Tape the edges of the crumpled paper to the cardstock so that it looks like a relief
map with ridges and valleys.
Place the cardstock in the shallow pan.
Use a different colored marker to “highlight” each ridge.
Draw the landscape that has been created by the crumpled paper in the data
section. Be sure to show the colored ridges.
Gently spray the ridges with the water bottle. Continue to spray the ridges until
the pattern of flow for the water is evident.
Draw the landscape after the “rain” in the data section. Be sure to show the flow
of water (how the color spread).
