Transcript Slide 1

Warm-up (Day One)
1.
Name the 6 biomes that you have studied.
2.
What 2 abiotic factors determine climate,
and the type of biomes that can exist?
3.
Name the 3 global cycles that you have
learned.
4.
What tools could a scientist use to observe
how the biomes and cycles relate to each
other?
1
Observing relationships & changes in Biomes:
We can use satellites to look at the “big picture.”

Relating global observations to our local environment

Our Biome

Warm-up (Day Two)
1.
What are some ways that humans have
altered our biome to suit our lifestyle?
2.
Can altering a biome impact temperature and
precipitation in the region?
3.
Can altering a biome impact cycles: water,
nutrients and carbon?
4
We saw how different biomes change with the
seasons, and observed human made changes to
in our own biome.
Now we are going to look at changes in
different biomes over time due to human
impacts
For the following images, decide whether or
not the: water, nitrogen, and carbon cycles are
effected by changed in these biomes.

What are three examples of human
activities that impact to the surface of
the earth?
What is an example of evidence that
the earth’s climate has been impacted?
Name one thing that humans can do to
lessen these impacts.
