ESSENTIAL QUESTIONS:
1. Why is Earth suitable for life?
STUDENTS WILL KNOW:
STUDENTS WILL BE ABLE TO:
a. The Arrhenius acid-base
theory.
1. Explain the chemical composition of acids and
bases.
b. Scientists use a variety of
instruments to measure pH.
2. Explain the change of pH in neutralization
reactions.
c. The reaction that describes
the formation of acid rain.
3. Identify neutralization reactions.
d. Earth’s atmosphere acts as a
thermal blanket, supports a
water cycle, is a source of
nitrogen and carbon, distributes
heat from warm to cool regions,
and shields a surface from
harmful radiation.
e. Chemical and physical
processes exist, which cause
carbon to cycle through the
major earth reservoirs.
f. Greenhouse gases absorb,
store, and re-radiate energy
from the sun.
4. Explain how the release of sulfur dioxide into
the atmosphere can form acid rain, and how
acid rain affects water sources, organisms, and
human-made structures.
5. Explain and illustrate the major characteristics
of Earth that enable it to sustain life.
6. Diagram the relationships between the living
and the non-living factors in the
biogeochemical cycles.
7. Identify general challenges of space
colonization.
8. Appreciate the vastness and complexity of the
universe.
9. Evaluate the habitability of planets and moons
g. The accumulation of CO2 in
beyond Earth in terms of temperature, water,
the atmosphere increases Earth’s
atmosphere, nutrients, and energy (TWANE).
greenhouse effect and causes
climate change.
10. Calculate the probability of life beyond Earth
applying the Drake equation.
h. The presence and
composition of a planet or
moon’s atmosphere can make
them warmer or colder then their
expected temperature.
i. The environmental conditions
of space provide significant
threats to the health and wellbeing of exposed organisms.
k. How the light-year is used in
measurement of space-time.
l. Humans and Earth are a small
piece of an enormous and
diverse cosmic system. No one
knows if the universe is infinitely
large, or even if ours is the only
universe that exists.
m. Earth is one planet of a single
star in a galaxy of hundreds of
billions of stars.
n. Biogeochemical cycles
contain both living and nonliving
factors, some of which can
theoretically be emulated in a
biosphere.
