2. Why Teach Environmental Science?
1. Environmental topics relate to
everyday life.
Air
Water
Energy Resources
Waste Management
3. 2. It promotes environmental
literacy among students.
So they can make informed decisions
to protect themselves, their families,
and their communities against
environmental problems.
4. 3. We live in a vulnerable
world.
How we care for the environment now
will determine our future.
5. How should we teach
Environmental Science?
1. Conduct investigative activities.
Apply the methods of science – observe,
determine the problem, gather and
analyze data, infer, make conclusions.
6. 2. Bring students outside the classroom.
to observe and understand the local environment
to know what’s going on in their community
7. 3. Teach students how to think.
Provide situations / exercises where they will explore
different perspectives of an environmental issue.
Role –play.
8. 4. Do service – learning.
Combine environmental lessons with community service:
waste recycling programs
water quality monitoring
cleanliness campaign
promote environmental awareness through various media
11. 6. Update using newspapers /
magazines, the Internet
Know about what’s going on in the community.

19. Properties of Water
•Water is a polar substance, with hydrogen bonds that make the forces of
attraction between the molecules of water stronger

20. •It has a high heat capacity--it can store a large amount of heat
without a large change in temperature.
21. It has a high heat of
vaporization
(540 calories per gram of
H2O).
It absorbs a large amount
of heat energy as it
evaporates.
It also releases a large
amount of heat as it
condenses.
22. •boiling point at sea level = 1000C
melting point = 00C
It has a high
surface tension,
and a high
wetting ability.
23. Major Indicators of Water Quality
Transparency
Water temperature
Dissolved oxygen
pH
Electrical Conductivity
Salinity
Alkalinity
Nitrate
24. Soil and Land Resources
Soil Characterization
Growing a Vegetable Garden
Hydroponics
25. Energy Resources
A Study of a Coal-Fired Power Plant
(Production and Distribution of
Electricity)
Estimating Electricity Consumption
A Study of a Geothermal Power Plant
26. Integrated Waste Management
Types of Wastes – Biodegradable,
Nonbiodegradable
Plastics in Our Lives (Comparing
Polymers)
Reuse, Recycle
