Klein ISD
Unit Overview: Systems
CONCEPT/S:
Science Curriculum
Grade 9
ENDURING UNDERSTANDING:
(Is worth remembering for a lifetime and has lasting value for the student)
 Organization
 Interactions
 A system is a collection of cycles, structures, and
processes that interact.
TOPIC/S:
 Change and constancy occur in systems, and are an
integral part of maintaining homeostasis in
organisms.
Interactions of Human Body
 Regulation
o Nervous
o Endocrine
 Nutrient Absorption
o Digestive
o Circulatory
 Reproduction
 Defense
o Integumentary
o Immune
Interactions of Plants
 Transport
o Roots
o Stems
o Leaves
 Reproduction
o Spores
o Flowers
o Cones
 Response
o Tropism
o Adaptation
Organization of Living Things
 Kingdoms/Domains
 Binomial Nomenclature
 Dichotomous Key
 Cladograms
 Phylogeny
ESSENTIAL QUESTIONS:
GUIDING QUESTIONS:
(Universal questions worth contemplation and exploration by the student)
(Fundamental queries that guide the search for student
understanding)
1. How do you organize your closet?
2. What are some signs that indicate that you are sick?
1. What advantages are there for categorizing
living things in both the Scientific
Community and Public?
3. Does a plant always grow toward the sun?
4. How do plants help and harm you?
2. How does taxonomy use hierarchal
classification systems to illustrate the
relatedness of organisms?
3. How are plant structures such as roots,
stems, and leaves, related to their functions?
4. How are animal structures such as blood,
muscle, and epithelium related to their
functions?
5. How do organs and organ systems work to
perform the functions of regulation, nutrient
absorption, reproduction, and defense?
6. How are microorganisms beneficial to the
health of animals and plants, and to the
ecosystems that they live in?
TEKS/SEs
CONTENT (TEKS)
PROCESS (SE)
The student will…
By…
(5)…know how an organism grows and the
importance of cell differentiation.
5(B)…examining specialized cells, including roots,
stems, and leaves of plants; and animal cells
such as blood, muscle, and epithelium.
(8)…know that taxonomy is a branching classification
based on the shared characteristics of organisms
and can change as new discoveries are made.
8(A)…defining taxonomy and recognizing the
importance of a standardized taxonomic
system to the scientific community.
8(B)…categorizing organisms using a hierarchical
classification system based on similarities
and differences shared among groups.
8(C)…comparing characteristics of taxonomic
groups, including Archaea, bacteria, protists,
fungi, plants, and animals.
(10)…know that biological systems are composed of
multiple levels.
10(A)…describing the interactions that occur among
systems that perform the functions of
regulation, nutrient absorption, reproduction,
and defense from injury or illness in animals.
10(B)…describing the interactions that occur among
systems that perform the functions of
transport, reproduction, and response in
plants.
10(C)…analyzing the levels of organization in
biological systems and relate the levels to
each other and to the whole system.
(11)…know that biological systems work to achieve
and maintain balance.
11(A)…describing the role of internal feedback
mechanisms in the maintenance of
homeostasis.
11(C)…summarizing the role of microorganisms in
both maintaining and disrupting the health of
both organisms and ecosystems.

STUDENT OBJECTIVE
5 E LESSONS
Lesson 1:
Lesson 2:
Lesson 3:
(“I can” statements should
be displayed for students)
I can:
…identify and describe the
specialized cells in plants,
such as roots, stems and
leaves.
…identify and describe the
specialized cells in
animals, such as blood,
muscle and epithelium.
…define taxonomy and can
recognize the importance
of the taxonomic system.
…categorize organisms into
the classification system
by their similarities and
differences.
…identify and compare the
major characteristics of
organisms in each
Kingdom.
…describe how systems work
together to carry out
processes such as
regulation, nutrient
absorption, reproduction,
and defense from injury or
illness in animals.
…describe how plants
transport nutrients,
reproduce, and respond to
their environment.
…analyze the levels of
organization and know the
order from cell to
organism.
…relate each level of
organization to the entire
system as a whole.
…describe what homeostasis
is and how it works as an
internal feedback
mechanism.
…summarize how bacteria
can help and/or hurt
organisms and ecosystems.
