Daily Objective:
By the end of today I should be able
to…
•Identify and clarify
misunderstandings in chapter 3
•Differentiate between weather and
climate
•Identify factors that influence
climate
Entrance Activity:
•Grab a test reflection sheet off of
the first counter and glue it onto
your test reflection page please.
Weather and Climate



Weather: day-to-day condition of Earth’s atmosphere.
Climate : average conditions over long periods and is
defined by year-after-year patterns of temperature and
precipitation.
Microclimates: mini changes within a climate
Example: Northern Hemisphere, south-facing sides of trees and
buildings receive more sunlight, and are often warmer and
drier, than north-facing sides. These differences can be very
important to many organisms.

Daily Objective:
By the end of today I should be able
to…
•Describe the greenhouse effect
Entrance Activity:
•Open your book to page 97.
•Copy/draw figure 4-1 in your
notes. (it should take up a
1/4 of a page)
Factors That Affect
Climate
 solar energy trapped in the
biosphere
Latitude
transport of heat by winds and
ocean currents
Solar Energy and the
Greenhouse Effect
O
The main force that shapes our climate is solar
energy that arrives as sunlight that strikes Earth’s
surface.
O
Some of that energy is reflected back into space,
and some is absorbed and converted into heat.
Solar Energy and the
Greenhouse Effect
– Some of the heat also radiates back into
space, and some is trapped in the
biosphere.
– The balance between heat that stays in
the biosphere and heat lost to space
determines Earth’s average temperature.
Solar Energy and the
Greenhouse Effect
– Earth’s temperature is largely controlled by
concentrations of three atmospheric gases—
carbon dioxide, methane, and water vapor.
– These “greenhouse gases” function like
glass in a greenhouse, allowing visible light
to enter but trapping heat through a
phenomenon called the greenhouse effect.
Solar Energy and the
Greenhouse Effect
– If greenhouse gas concentrations rise, they
trap more heat, so Earth warms. If their
concentrations fall, more heat escapes, and
Earth cools.
– Without the greenhouse effect, Earth would
be about 30°C cooler than it is today.
Latitude and Solar Energy
• Do warmer particles sink or float? Why?
•
Air that is heated by
warm areas of Earth’s
surface—such as near
the equator—rises,
expands, and spreads
north and south, losing
heat along the way.
•
As the warm air
cools, it sinks.
•
The unequal
distribution of heat
across the globe creates
wind and ocean
currents, which transport
heat and moisture.
•
Earth has winds
because warm air is less
dense and rises, and
cool air is more dense
and sinks.
•
In cooler regions,
near the poles, chilled
air sinks toward
Earth’s surface,
pushing air at the
surface outward.
•
This air warms as it
travels over the
surface and rises.
•
These upward and
downward movements of air
create winds.
•
Winds transport heat from
regions of rising warmer air to
regions of sinking cooler air.
•
Earth’s rotation causes
winds to blow generally from
west to east over the
temperate zones and from east
to west over the tropics and the
poles.
•
•
•
Similar patterns of heating and cooling occur in
the oceans.
Surface water is pushed by winds.
Ocean currents, like air currents, transport
enormous amounts of heat.
•
Warm surface currents add moisture and heat to
air that passes over them.
•
Cool surface currents cool air that passes over
them.
•
In this way, surface currents affect the weather
and climate of nearby landmasses.
•
Deep ocean currents are caused by cold water
near the poles sinking and flowing along the
ocean floor.
•
This water rises in warmer regions through a
process called upwelling.

Daily Objective:
By the end of today I should be able to…
•Define a niche
•Describe the role of competition
plays in shaping communities
Entrance Activity:
•Please, write a score about how well
you feel that you meet each of
today’s objectives RIGHT NOW.
Rate yourself 1-5, 1 being you have
absolutely no idea, 5 being you know
it well enough to teach it to others.
TOLERANCE!!
 Organisms occupy different places because each
species has a range of conditions under which it can
grow and reproduce
What happens when an organism
is pushed outside of its tolerance?
DEATH
Habitat is an organism’s address
NICHE
WHAT IS THE
DIFFERENCE BETWEEN
HABITAT AND NICHE?
Keystone Species

A single species that can cause
dramatic changes in the structure
of a community
The sea otter is another example of a keystone
species in the Pacific Northwest. These mammals
feed on sea urchins, controlling their population.
If the otters didn't eat the urchins, the urchins
would eat up the habitat's kelp. Kelp, or
giant seaweed, is a major source of food
and shelter for the ecosystem. Some species of
crabs, snails, and geese depend on kelp for food.
Many types of fish use the huge kelp forests to
hide from predators. Without sea otters to
control the urchin population, the entire
ecosystem would collapse.

Daily Objective:
By the end of today I should be able to…
• .Describe the role of competition
plays in shaping communities
Entrance Activity:
Without USING YOUR NOTES,
Try to describe the difference between
a niche and a habitat.
Community interactions:
COMPETITION
Space
Mates
Water
Resources

Predation: One animal
captures and feeds off of
another
Symbiosis: two species live closely
together
You and your group members will create a QUICK
skit about one of the types of community
interactions…
It should explain the type of interaction (PG 102104)

You will present them in 15 minutes

• Describe how ecosystems recover
from a disturbance
0000000000
Entrance Activity
1. Please grab two pieces of plain white
paper (you can grab them off of the
lonely stool at the front of the room)
2. Open Your book to page 106and
quickly read through the two types of
succession.
{
Ecological
SUCCESSION
Predictable changes that occur in a
community over time
Example: Older inhabitants die out, new
ones come to inhabit
Primary Succession
-Inhabitation that occurs on surfaces
where there is no soil
-Example: after volcanic eruptions or
when glaciers melt
Pioneer species
The first species
to populate
an area
Example:
LICHENS
Combo of
fungus and
algae.
BREAK DOWN
ROCK AND FIX
NITROGEN!
Why might this be
an awesome
thing in a
primary
succession
example?
When a
disturbance
removes the
community but
leaves the soil
Example:
wildfires,
abandoned
farm land
