Strand 3: Characteristic and Interactions of Living Organisms
2. Living organisms carry out life processes in order to survive
Major Objectives IS Suggested Activities
These samples activities offer ideas and are not
Concept A: The cell contains a set of structures
called organelles that interact to carry out life
processes through physical and chemical mean
Scope and Sequence – Cells and Body Systems
meant to limit teacher or student resourcefulness.
Grades 6 & 8
Suggested Assessments
These samples assessments offer ideas and are not
meant to limit teacher or student resourcefulness
a. Recognize that the cell membrane helps regulate
the transfer of materials in and out of the cell
R
a. Students will model a cell membrane using
diffusion membranes (1.2; 1.3)
a. Compare a cell membrane to a structure in a
city or factory.
b. Recognize that the function of the chloroplast is
photosynthesis
Concept B: Photosynthesis and cellular respiration
are complementary processes necessary to the
survival of most organisms on Earth
Scope and Sequence – Cells and Body Systems
b. Students will use Elodea or a similar plant to
produce Carbon Dioxide. (1.2; 1.3)
Grade 6 & 8
b. Students will test for carbon dioxide
production with Bromothymol blue or other
test chemical.
a. Recognize that photosynthesis is a chemical
change with reactants (water and carbon dioxide)
and products (energy-rich sugar molecules and
oxygen) that takes place in the presence of light
and chlorophyll
R
a. Using plants, students will perform a test in
which varying levels of light are used. They
will discuss its effect on photosynthesis. (1.2;
1.3;4.5)
a. Students will predict the effects of a lack of
oxygen on the cell.
b. Recognize that oxygen is needed by all cells of
most organisms for the release of energy from
nutrient (sugar) molecules (Do NOT assess the
term cellular respiration)
R
b. Students will discuss the work of Priestly and
his discovery of oxygen. (2.3; 4.6)
b. Students will prepare a report on the work of
Joseph Priestly and assess the importance of
his isolation of oxygen to the understanding of
life.
c. Describe the importance of the transport and
exchange of oxygen and carbon dioxide to the
survival of the organism
c. Students will model and discuss the Carbon
Cycle. (1.2; 1.3)
c. Students will trace the flow of carbon as it
moves though the environment and explain its
relationship to the production of oxygen.
