Student Exploration: Water Cycle
Directions: Follow the instructions to go through the simulation. Respond to the questions and
prompts in the orange boxes. This should NOT be word for word like another student. If
so, you will need to redo the assignment
Vocabulary: aquifer, condensation, evaporation, freezing glacier, melting, phase change, precipitation,
reservoir, runoff, transpiration, waler cycle
Prior Knowledge Question (Do this BEFORE using the Gizmo.)
The xvaler thal comes oul of your faucet at home used to be in the ocean. How did the ivaler get from the
ocean Io your waler faucet?
Waler goes through lhe water cycle. it gets evaporated, then condenses into a cloud which then
precipitates in the form of rain snow, hale sleet and many more. The water is deposited into
fresh water rivers and it then gets transported to people s homes through pipe systems after it
gets treated in order to be consumed.
Gizmo Warm-up
Waler on Earth is always in motion. These motions form a
repealing circuit called the water cycle. The Water Cycle Gizmo
allows you Io explore lhe different paths water lakes as it moves
from Earth s surface to lhe atmosphere and back.
1. Click Oceans. Whal percentage of Earth's waler is found in
lhe oceans?
97.25%
2. Click Atmosphere. How does the Sun cause water I o move
from lhe oceans Io the atmosphere?
Water gels transported into the atmosphere through evaporation where the water gets healed
up and it rises into the atmosphere as vapor.
3. Click Clouds. How do clouds form?
The evaporated water vapor gets cooled and condensed into small water droplets that form
clouds.
4. Click Precip {rain}. ('Precip" is short for precipitation or water falling to Earth s surface ) What causes il
I o rain?
The water droplets get bigger and heavier, and then they drop onto the Earth in many forms

like rain, snow, hail, and many more
5. Click Oceans again, and then choose the PATH tab. Because it has the same beginning and end. the path
is a complete cycle. How many steps does this cycle have?
It has around 4-5 steps.
Activity: Getthe Gizmo ready:
The water cycle Select the SIMULATION lab. and click Reset
Question: What are the parts of the water cycle?
1. Collect djt a: Create two water cycles using the Gizmo. Each cycle should have al least four steps and
should begin and end al the same location. Choose any starting point from the list on the right. When the
cycle is complete, choose the PATH tab and write the steps below.
Cycle 1: Oceans atmosphere, clouds, percip(rain), vegetation
Cycle 2: Reservoir. Industry, atmosphere, clouds, precip(snow)
2. Analyze: Use the information presented in the Gizmo to answer the following questions.
A. What percentage of Earth s waler can be found in soil?
B. What percentage of Earth s waler is stored in ice and snow?
C. What percentage of Earth s freshwater is stored in ice and
snow?
D. What percentage of Earth's water is found in lakes?
E. What is transpiration? (Hint: Click lhe Vegetation button.)
0.005% of water in soil
1.9% total water in ice &
snow
68.7% of freshwater in
ice & snow
0.009% of water in lakes
Plants use their roots Io
absorb water from soil,
and release water vapor
from their leaves in
trans porta lion.
About 70% of waler used
by people is used for
agriculture.
In lhe United Stales 35%
water is spent on
agriculture but 50% is
spent on industry.
F. What human activity uses the most water worldwide?
G. What human activity uses the most waler in the United
States?
