Strand 4: Life Science

Concept 5: Matter, Energy, and Organization in

Living Systems (Including Human Systems)

Understand the organization of living systems, and the

role of energy within those systems.

PO 1.

Compare the processes of photosynthesis and cellular respiration

in terms of energy flow, reactants, and products.

Set

Bellwork (on screen; Day One): Get together with your lab partners and

• Active Participation

discuss the photosynthesis experiments you carried out. How can you

• Past Experience

improve the techniques you used? How do you think your results might

• Relevancy

be different if you repeated your experiments with chloroplasts from

different plants?

(Day Two): Review with your group and be prepared to share your

hypothesis.

(Day Three): What kind of graph(s) do you plan to use to present your

results? What will the x-axis and y-axis labels be? What units of

measurement did you use?

Lesson Overview

1. Students (3-4 students per lab group) brainstorm ideas for comparing

photosynthesis activity of native plants to that measured in the

previous experiment. Plant tissue samples will be obtained primarily from

plants on the school grounds or nearby. Possibilities include both native and non-

 Response

native desert-adapted plants of several functional types. For some, chloroplast

isolation will be straightforward, but others will present some challenges,

increasing the realism of the research.

 Questions

2. Each student group develops a prediction/hypothesis about

differences in photosynthesis between spinach chloroplasts and those

from desert plants. Desert adaptations have not yet been discussed in AP

• Active Participation

Biology, but many students will have some prior knowledge of general desert plant

adaptations and biochemistry (C

vs. C

vs. CAM plants, etc.).

3. Student groups write up an experimental procedure and list of

materials needed. Students have standard lab report format, and previous

experimental design experience. It is expected they will carry out variations of the

spinach chloroplast experiment, but they have the freedom to go in different

directions.

4. Each group carries out their experiment and evaluates their

hypothesis including a discussion of problems that occurred and

possible improvements to their chosen method.

5. Each group presents their results to the class using the electronic

medium of their choice.

Teacher introduces the activity and monitors and guides discussion and

progress when needed.
