In the next
month or so, we will learn about ecosystems, biomes, and human
impacts on the environment. By the time we have finished this
unit, you should be able to explain the following Big Ideas:
- Matter and
energy together support life within an environment.
- Living
things within an ecosystem interact with one another and the
environment.
- Humans and
human population growth affect the environment.
Listed below is
an activity you can do at home. The activity involves
abserving an ecosystem in your own neighborhood and predicting how
it might change over time. Note that an ecosystem can be any
area where living and nonliving factores interact. It might be
a tree, a wall, a park, or a city block. It could be your
backyard.
- Take a
walk. Find a place where you can identify at least three
different organisms that live together in that area.
- Talk about
how the organisms interact. In what ways do the organisms
help one another? Do they compete? If so, how?
- Discuss how
the area you are observing might change over the next week,
month, or year. What might change? What might stay
the same?
