Water Cycle
I am the water that falls from the sky in the form of rain, snow, sleet, or hail.
Precipitation
Which of the following is the best example of a new substance forming as a result of an interaction?
A. lighting a match
B. cutting a piece of paper
C. popping a balloon
D. hitting a nail with a hammer
A. Lighting a match
Name a quantitative property.
Any kind of property that can be measured.
Weight, height, length, temperature, how many, etc.
Name a frozen form of precipitation.
snow, sleet, or hail
How does the Sun's energy impact the water cycle?
It turns liquid water into water vapor.
I flow across the surface of the Earth after a rain or when snow melts.
Runoff
Does slicing pizza result in a new substance forming?
No, it is still pizza after it is sliced.
Name a qualitative property.
Anything that can be observed using the senses.
color, texture, odor, flexibility, etc.
When water warms up it changes from a liquid to a gas. In the water cycle, what source of energy causes this change?
the sun
How might precipitation affect runoff on Earth? Give an example to support your idea.
Example response: Too much precipitation could cause a lot of runoff causing flooding.
My heat energy evaporates the accumulated water on the Earth.
Sun
Does melting cheese result in a new substance being formed?
No, the cheese is still cheese.
True or false. Qualitative properties of a banana are it is yellow and has pointy ends.
True
Which of the following is an example of transpiration?
A. Rain falls from clouds and flows over Earth’s surface.
B. The Sun’s energy changes dew drops to water vapor.
C. Snow melts and forms puddles that will freeze again.
D. The leaves of a tree release water vapor into the air.
D. The leaves of a tree release water vapor into the air.
How are evaporation and transpiration alike?
Both involve water turning into vapor.
Water vapor cools down and turns back into a liquid causing clouds to form.
Condensation
Does baking a cake result in a new substance being formed?
Yes.
Before it was baked, it was not cake.
True or False A quantitative property of my car is that it is large.
True. This has to do with size, which can be measured.
Water condensed on the outside of my glass forming droplets, but sitting in the sun, the water droplets disappeared. What caused the water droplets to disappear?
evaporation
How are evaporation and condensation connected in the water cycle?
Evaporation causes water vapor to rise into the atmosphere. Condensation cools the vapor to form clouds. Without evaporation there would be no clouds.
I am the evaporation of water from the leaves of plants.
Transpiration
Does burning your toast result in a new substance being formed?
Yes. The change in color shows a new substance formed.
Qualitative or Quantitative?
The toothbrush is wet, sticky, and is 7 inches long.
Both!
Name 2 parts of the water cycle that would cause the water level to rise in a pond.
Precipitation and runoff
How is heat energy involved in the process of condensation?
Heat energy cools or gets less which allows the water vapor to cool and turn back into liquid, causing condensation.
