Review
Final Exam/ CBA #2
Flexible due to testing
* indicates Supporting Standard
Process Skills (8.1 – 8.4) are embedded throughout investigations.
Teachers will have to adjust time allotments to allow for lost teaching days due to testing or special campus activities. The order of topics may be rearranged
or integrated within a grading period, but topics shouldn’t flow into the next grading period.
Overview for Each Unit
Unit 1
When conducting laboratory and field investigations it is extremely important to follow safety procedures and use
environmentally appropriate and ethical practices.
Unit 2
There are characteristics of Earth and relationships to objects in our solar system that allow life to exist.
Relationships exist between organisms and their environment. Different environments support different living
organisms that are adapted to that region of Earth. Matter and energy are conserved throughout living systems.
Organic compounds are composed of carbon and other elements that are recycled due to chemical changes that
rearrange the elements for the particular needs of that living system. Radiant energy from the Sun drives much of the
flow of energy throughout living systems due to the process of photosynthesis in organisms described as producers.
Most consumers then depend on producers to meet their energy needs. Decomposers play an important role in
recycling matter.
Diversity is a result of changes in traits that sometimes occur in populations over many generations. One of the ways
changes can occur is through the process of natural selection.
Unit 3
Force, motion, and energy are observed the environment in several ways. Weather systems such as hurricanes, floods,
and tornadoes can shape and restructure the environment through the force and motion evident in them. Weathering,
erosion, and deposition occur in environments due to the forces of gravity, wind, ice, and water.
Unit 4
All living organisms are made up of smaller units called cells. All cells use energy, get rid of wastes, and contain genetic
material. Cells can organize into tissues, tissues into organs, and organs into organ systems. Living systems at all levels
of organization demonstrate the complementary nature of structure and function. Plant and animal cells have
specialized internal structures within them that allow them to obtain energy, get rid of wastes, grow, and reproduce in
different ways.
Plants are living organisms that have specialized internal structures within them that allow them to obtain energy, get
rid of wastes, grow, and reproduce. Force, motion, and energy are observed in living systems in several ways. Force and
motion can describe the direction and growth of seedlings, turgor pressure, and geotropism in plants.
Reproduction is a characteristic of all living organisms, including plants. Whether sexual or asexual, the instructions for
traits are governed in the genetic material that is found on genes within a chromosome from the parent.
Unit 5
All organisms obtain energy, get rid of wastes, grow, and reproduce. Our body systems function together to maintain
homeostasis and allow humans to carry out all the processes necessary for life. The integumentary system provides
protection and removes wastes, interactions between muscular and skeletal systems allow the body to apply forces and
transform energy both internally and externally, the nervous system responds to stimuli, circulatory and respiratory
deliver of oxygen and nutrients and get rid of wastes, digestive and excretory systems physically and chemically break
down food to extract nutrients and energy and excrete wastes, while endocrine and reproductive systems regulate
balance of chemicals and allow for continuation of the human species.
