th
This benchmark is currently being taught in the 7 grade Health Class. It is the responsibility of the
7th grade science teacher to be sure this is taught. Should the Health Class be changed, this
benchmark will be taught in 7th grade science.

Generate scientific questions about the world based on observation.
Use sources of information in support of scientific investigations.
Evaluate the strengths and weaknesses of claims, arguments, or data.

Vocabulary/Key Concepts
Context
Systems/Processes:
• digestion
• circulation
• respiration
• endocrine
• reproduction
• skeletal
• muscular
• nervous
• excretion
• transport
• growth
• repair
Interrelations of body systems during selected
activities:
• skeletal
• muscular
• nervous
• circulatory
• respiratory systems during physical exercise
Knowledge and Skills
Students will:
• Explain how selected systems work
together to carry out body functions
• Integrate key concepts through illustrations
of relationships between systems
• Examine how these functions take place in
both complex and simple organisms
Students will explain the relationships between
skeletal, muscular, circulatory, nervous and
respiratory systems during physical exercise.
Examples:
• The circulatory system transports the food and
oxygen to the cells and carries carbon dioxide and
other waste products away from the cells.
• The digestive system breaks down food into small
particles and enables them to be absorbed into the
blood stream (part of the circulatory system).
• The skeletal, muscular, circulatory, nervous, and
respiratory systems during physical exercise
All body systems work together for optimal
functioning of an organism. Students will integrate
key concepts through illustrations of relationships
between systems. Students will examine how
these functions take place in both complex and
simple organisms.

Instruction
Assessment
In small groups students will research two body
systems and determine how these two systems are
interrelated.
Using any technology available to them, students will
create a multi-media presentation on their results.
Peer review of initial presentation and / or showing
of entire project to group other than their class
such as the PT0, other classes, and civic groups.
(Give students rubric before activity.)
Scoring Rubric:
Have students work in small groups to write and
create a multi-media presentation that shows the
functions and interactions among the circulatory,
respiratory, and digestive systems.
In their groups, students will:
• Select and research a body system
• Assign roles for each group member/organ
• Write a short skit connecting the actor’s action
with their specific organ(s) or other activity to
present organ function
• Create a presentation for the class
To culminate the activity, the class will create a
presentation that combines the three body systems.
The cumulative presentation could review:
• The function of the body systems
• How systems work together to carry oxygen
and nutrients to the cells and remove waste
from the cells
Criteria: Accurate explanation of functions:
Apprentice - Explains functions of one to two
systems, but gives sketchy details.
Basic - Explains functions of three systems, but
gives little detail about how they interrelate.
Meets - Explains functions of all three systems
and discusses how they work together.
Exceeds - Explains in detail the functions of all
three systems and discusses how they work
successfully together.
Criteria: Effectiveness of collaboration:
Apprentice - Participates with some team
members in writing, performing, or producing the
project.
Basic - Participates with most team members in
writing, performing, or producing the project.
Meets - Participates with all team members in
writing, performing, or producing the project.
Exceeds - Participates with all team members
equally in writing, performing, or producing the
project.
Teacher Notes:
“The human organism has systems for digestion, respiration, reproduction, circulation, excretion, movement, control, and
coordination, and for protection from disease. These systems interact with one another.” (NSES) For example, the
skeletal and muscular systems work together to provide support and locomotion; the digestive, circulatory, respiratory and
excretory systems work together to get energy-containing substances to the cells and waste products out of the body; the
nervous and endocrine systems work together to allow the organism to respond to events in its environment.(JCISD)
The benchmark about systems and processes in animals does not require students to name the parts of each system.
They need to learn the functions of each system and how systems work together to accomplish those functions.
The emphasis in this unit is on human body systems, although what students learn is applicable to many other animals.
