Essential Question:
1. How do systems maintain balance?
[How does the body detect changes, make changes, and stop changing when the imbalance is corrected?]
Interdisciplinary / TOK links:
When does something "good" become something "bad?" (or) What problems result from imbalance in systems?
Learning Objectives:
6.1 - 6.6 (see DP Biology Subject)

INTRODUCTION to photosynthesis
- Introduce: photosynthesis is a combination of 2 processes:
- Diagram electron transport chain in mitochondria (parallel to photosynthesis here so this is VERY important
-
|
All students do chromatography according to Carolina's "AP Bio #4: Pigments & Photosynthesis:
- collect chromatography papers and paste in lab book
- record Rf values for all 4 pigments (note: 1 is at solvent front)
- attemtp to identify pigments based on Rf values using internet resources. (note: source must be "relaible" not something like answers.com)
HL students (extra hours): crush geranium leaves in ethanol and use spectrophotometer to experimentally determine maximum absorbance of chlorophyll
|
(C) coloring for chloroplast, thylakoid system, and RuBC system
(B) complete spectrophotometry
