Download 7-1 Life Science Focus Guiding Question: How are organisms

Life Science Focus
Guiding Question:
How are organisms structured to ensure efficiency and survival?
Content Standards:
All organisms are made up of one or more cells; each functions more or less independently.
Multicellular organisms need specialized structures and systems to perform basic life functions.
Benchmark/ Expected performance
Students will:
1. Know the basic structures and functions of an
animal cell including nucleus, cytoplasm,
mitochondria and cell membrane and how they
function to support life,.
2. Know how the human muscular/skeletal system
supports the body and allows movement.

Guiding Question:
How do science and technology affect the quality of our lives?
Content Standards:
Technology allows us to improve food production and preservation thus improving our ability to meet the
nutritional needs of growing populations.
Benchmark/ Expected performance
Students will:
1. Know what bacteria are and how they replicate and
cause food spoilage.
2. Know the methods (refrigeration, freezing,
dehydration, pasteurization, pickling, irradiation)
that have been developed to prevent food spoilage
caused by bacteria.
3. Know how these methods prevent food spoilage
caused by bacteria.

Earth Science Focus
Guiding Question:
How do internal and external sources of energy affect the Earth’s systems?
Content Standards:
Volcanic activity and the folding and faulting of rock layers during the shifting of Earth’s crust affect the
formation of mountains, ridges and valleys.
Glaciation, weathering, and erosion change the Earth’s surface by moving earth materials from place to
place.
Benchmark/ Expected performance
Students will:
1. Know how folded and faulted rock layers provide
evidence of the gradual up and down motion of the
Earth’s crust.
2. Know how glaciation, weathering, and erosion
create and shape valleys and flood plains.
3. Know how the boundaries of tectonic plates can be
inferred from the location of earthquakes and
volcanoes.
