BE AN H2O HERO: CONSERVATION
Lesson Ten
Overview
Water is absolutely essential for life. All
living things require water for survival.
Water is one of our most precious
resources and because of its
importance in our lives, we must
respect it. The practice of water
conservation is an important concept to
teach students.
If we conserve water by changing our
lifestyles, we can have plenty of water
for the future. Although there is plenty
of water on Earth, it is not always
available in sufficient quantity. The
impact of everyone conserving water at
home can make a huge impact.
At the end of this lesson, the students
will be able to give an oral definition of
the new term: conservation, tell one
personal demand he or she places on
water, and write ways to conserve
water around the home.

Materials
1. Copies of Rain Gauge Journal Page(Journal page #11-enough for each
student)
2. Sophie’s Garden (Story CD-Story
#1)
3. H2O Hero C.O.R.E. Values Poster
Advanced Preparation
1. Gather the materials
2. Ask the students to collect all of their Rain Gauge Journal pages and
bring them when they go outside. Before going outdoors, ask the
students to add up all the rain they have measured during the last four
days (if any). Lead a class discussion about how much rain (if any) they
have had during the last four days.
Setting the Stage
1. Remind students that in Lesson Seven, we discussed how the lack of
water resources can affect a community. In Lesson Eight, we discussed
the lack of fresh water that exists on the Earth. Finally in Lesson Nine,
we discussed systems that sometimes need to be developed to deal
with limited water supplies. With a growing Earth population, it is
important that we conserve the water we have. What does water
conservation mean?
Water Conservation- To save and not waste water.
Do you think we have had enough rain over the last five days to
fill up the area creeks, rivers, lakes, and aquifers?
What do you think might happen if we didn’t get any rain for a
long period of time (maybe six months or a year)? (A: These
water bodies would begin to dry up).
Do people get their drinking water from any of these water
bodies? (A:Yes)
So what might happen if these water bodies dried up? (A:
Drinking water supplies might also begin to dry up)
Water conservation is one way that H2O Heroes can help save our
drinking water when we do not get a lot of rain.
Activity
1. Begin by reading the story, Sophie’s Garden (Story CD-Story #1) to
the class as they follow along.
[TEACHER: The purpose of this story is to show the class that students
their own age can become H2O Heroes and make an impact on their
community by saving water. When the story is completed, ask the
students to point out actions that the main character(s) took to help
save water resources. You might even need to have the students read
the story a second time for them to understand.]

Lesson Ten
2. After the story, lead a discussion with the class on what characteristics makes an H 2O Hero.
Another way to say that you are a water saver is to say that you are an H 2O Hero. H2O is another way to say water.
An H2O Hero is any girl or boy who is dedicated to protecting our water. H 2O Heroes come in all shapes and sizes.
But they all have one thing in common—H2O Heroes learn all they can about saving water and share what they learn
with others.
In this story, Sophie shows us how to be an H2O Hero. H2O Heroes here in San Antonio know how important it is to
conserve water and not pollute the water we have. In this lesson, we are going to talk about why it is important to
conserve water and what you can do to be an H2O Hero and help out.
Discussion
Discuss with the students how they can become H2O Heroes and help out their community by saving water. Tell the
students that H2O Heroes are committed to the C.O.R.E. values. Using the H2O Hero C.O.R.E. values poster, point
out the C.O.R.E. values that H2O Heroes should follow:
Community
H2O Heroes are good citizens and make their community a better place to live.
Ownership
H2O Heroes take ownership by identifying water issues in their community and offering solutions.
Responsibility
H2O Heroes do their part by conserving and protecting water around them.
Education
H2O Heroes learn all they can about saving water and share what they learn with others.
Outside Activity
1. Begin the outdoor exploration by having the class check the rain gauge placed in the school yard during Lesson
Five one final time. Is there any water (precipitation) today in the gauge? If so, how much water is there? Using the
Rain Gauge Journal Page (Journal page #11), have the students color in the amount of water found in the rain
gauge on the rain gauge illustration marked Day 5 with their blue crayon or colored pencil. If the gauge is empty, the
students should not color anything on the illustration.
2. Ask the students to add any rain fall amount from Day 5 (if any) to the total number that you discussed in the
classroom. Discuss with the students the total rain fall amount (if any) for the last five days of this exercise.
3. Ask students,
From what we have already learned in this program, how important are weather conditions to the water
cycle? (A: Vitally important. Energy from the sun which produces heat drives evaporation and heat
can be measured by the air temperature. The process of condensation forms clouds and wind speed
drives the clouds across the planet. The air is full of water that comes from evaporation,
transpiration, perspiration, and exhalation. Precipitation falls to the earth forming water bodies
including rivers, lakes, oceans, and aquifers).
Extension
Ask your students to take home the worksheet “Ways You Can Help Cactus Callie Conserve Our Water” and have
them discuss this with adults at home. They may wish to post up on the refrigerator or on a bulletin board at home to
remind them about how they can be an H2O Hero and help out.
