Grade 8 Science - Unit II Overview
|
Earth Systems
| In the
second unit, Earth Systems, the students will predict
changes in areas of the Earth that may occur over time,
such as plate movement, with the use of pictures and
stories.
Students will identify events that have led to
endangered species and make recommendations on how to
protect our future species.
Students will identify and describe human impact on
our soil, water and air quality.
Students will be able to identify the processes of
the rock cycle.
Students will analyze a water cycle diagram and show
the role of oceans, the sun and weather on the cycle.
Students will be able to analyze ocean data, such as
El Nino, La Nina and relate the data to the occurrence
of hurricanes and rainfall patterns in the U.S. Students
will be able to predict the climatic change when given a
particular weather effect.
Critical Questions:
- Why is the Earth constantly changing?
- How are the Earth's features altered by natural
events?
- What are the effects of human activities on
Earth's systems?
- Why is it important to conserve and recycle our
resources?
Suggested Time Frame: 6.5 weeks |

Predict land features from
crustal movement, such as plate tectonics and continental drift;
and changes in land forms, such as mountain building, erosion,
deposition and subsidence. (8.14 A) T8 |
|
Analyze and construct
topographic maps. (8.2 C & E) T8 |
|
Analyze and predict
the sequence of events in rock cycles, such as sedimentary,
igneous and metamorphic rocks, weathering, erosion,
sedimentation, deposition, heat and pressure. (8.12 A) T8 |
Describe interactions on the
Earth such as, weather, climate and the water cycle.
Relate the role of oceans to climatic changes through the
processes, such as evaporation, condensation, precipitation and
temperature regulation. (8.10 B, 8.12 B) T8 |
|
Analyze how natural
disasters, such as flooding, drought, asteroid impact and
climate change; and human activities, such as encroachment, over
hunting, pollution and conservation can alter Earth systems.
