7-E Learning Model
 An instructional model for constructivism
 Constructivism defined: A philosophy
of teaching science that allows
students to construct knowledge
through interaction with people and
phenomena.

The Reality of Biology
Photosynthesis
 Elicit
 Imagine that you are a plant.
What materials do you need to
carry out life processes?
 How would these materials be
utilized, and what would you
produce with them?

dependent reactions
 Granum…..…. “Stack of coins” Thylakoids
 Intergranum... Connects thylakoids
 Lumen………..“Cavity” Thylakoid space
 Stroma………..“Covering” The site of light
independent reactions
Photosynthesis
 MC.2.B.5 Compare and contrast the
structures of an animal cell to a plant
cell.
 MC.3.B.1 Compare and contrast the
structure and function of mitochondria
and chloroplasts.
 CDL.7.B.17 Describe the structure and
function of the major parts of a plant:
Roots, Stems, Leaves, Flowers

 Authentic Inquiry
Authentic Inquiry Science
 …..a multifaceted activity that involves
making observations; posing questions;
examining books and other sources of
information to see what is already known;
planning investigations; reviewing what is
already known in light of experimental
evidence; using tools to gather, analyze and
interpret data; proposing answers,
explanations and predictions; and
communicating the results
