Co-Requisite

1
Co-Requisite Content Standard SB3Students will
derive the relationship between single-celled and
multi-celled organisms and the increasing
complexity of systems. a. Relate the complexity
and organization of organisms to their ability
for obtaining, transforming, transporting,
releasing, and eliminating the matter and energy
used to sustain the organism.
2
Comparative Anatomy

• What a queer, funny, little bird a frog are.
• When he sit, he squat most.
• When he jump, he hop most.
• And he aint got no tail at all, hardly most.

3
BIG IDEAS

• Cellular Organization/ Specialization
• Adaptations
• Energy and Matter Transformation
• Cellular and Bulk Transport
• Metabolic Processes
• Growth, Development and Reproduction
• ETC.

4
Essential Questions

• How does multicellularity develop in embryos?
• Why do some organisms eat and others dont?
• How does an organism change stored energy into
  usable energy?
• How are organisms adapted to (transport,
  metabolize, excrete, etc.) matter and energy?
• Since all organisms perform similar processes,
  what might you expect about the stuff of which
  they are made?
• ETC.

5
Enduring Understandings

• The student will understand that some organisms
  consume complex organic compounds, and others
  have the ability to organize these compounds from
  inorganic materials using solar or chemical
  energy.
• The student will understand that very small
  organisms perform some functions seen in larger,
  more complex organisms.
• The student will understand that all organisms
  carry out metabolic activities within their cells
  to transform energy into the chemical energy
  of ATP.
• The student will understand that all organisms
  develop through specialization of structures,
  with multicellular organisms forming specialized
  tissues for specific functions.

6
Students will know

• The developmental progress of multicellular
  organisms due to specialization of cells.
• The relationships and differences between
  autotrophic and heterotrophic.
• The Chemical and Mechanical processes of
  (digestion, transport, absorption, storage,
  excretion, etc.)
• ETC.

7
Students will be able to

• Design experiments to test problems derived from
  careful observations.
• Demonstrate appropriate technique in all
  laboratory situations.
• Collect, organize, and graph data to show results
  of their experimental design.
• Write lab reports with an introduction of
  important concepts, a hypothesis, procedure,
  organized results, and a conclusion that
  evaluates the results in terms of the important
  concepts.
• Use data as evidence to support scientific
  arguments and claims in written or oral
  presentations.

UNIT DESIGN - EXCRETION Big Ideas

• Cellular and Bulk Transport
• The ExcretoryStructure- Simple to complex
• Small organisms to large organisms Comparative
  anatomy
• The Process of Excretion

9
Essential Questions - Excretion

• Why is diffusion and osmosis the only processes
  of excretion needed by many organisms?
• What is the relationship between metabolism and
  excretion?
• How is excretion accomplished in small and large,
  multicellular organisms?
• Why is an understanding of simple excretory
  structures and functions important to
  understanding complex structures?

10
Skills -Students will be able to

• Analyze the chemical makeup of excretory waste
  products.
• Write a lab report to include a discussion of
  concepts, a hypothesis, a report of procedures,
  results that are organized, and a conclusion that
  discusses the results in terms of the important
  concepts.

11
Knowledge - Students will know

• That the role of excretion in metabolism is to
  remove the wastes given off during physiological
  processes.
• That diffusion, osmosis, and active transport are
  involved in accomplishing excretion.
• That the excretory structures are similar in all
  multicellular organisms.
• The sequence of filtration, reabsorption and
  concentration accomplishes excretion of wastes in
  complex organisms.

12
Evidence of Understanding - Excretion

• Explain the role of excretion in metabolic
  processes.
• Compare and contrast the excretory functions of
  unicellular and multicellular organisms.
• Compare and contrast the excretory structures of
  small, simple organisms and large, complex
  organisms
• Explain the processes of filtration,
  reabsorption, and concentration of waste products
  as they occur in the human kidney.
