2.3 Macromolecules
Learning Objective: Differentiate between the structures and functions of four groups of macromolecules.
Learning Sequence:
1.

Predictive Writing – Individual/Small Group/Class
Vocabulary Skim – Individual/Small Group/Class
Directed Note Taking with a Guided Question – Individual/Small Group/Class
Semantic Feature Analysis – Small Group A/(Small Group B)/ Class
Summarizing the Semantic Feature Analysis
Predictive Writing: What do you know about carbohydrates, lipids, proteins, and nucleic acids?
Carbohydrates (CHO)
Lipids (L)
Proteins (P)
Nucleic Acid (NA)
Vocabulary Skim: Students skim the text looking for words they aren’t sure of (alone); Students work in small groups to
define words the students in the group knows; Groups will share the words for which they are uncertain with teacher;
Teacher allows class to respond to other teams; Teacher defines words the class could not figure out.
Directed Note Taking:
Guiding Question: What are the important features of each of the macromolecules?

Alone (10-20 minutes)- Students read the text and record concepts they believe is important in paraphrased form.
Students categorize notes in the four categories listed on the right.
Small Group (10 minutes)- Students share what they learned in the reading in small groups. They discuss their
interpretation and base their discussion in the text’s content.
Class (10 minutes) – Students share their interpretation of the text; and students ask questions to clarify what was
stated.

Complete Chart Showing Similarities and Difference Between each of the macromolecules
Small Group A – Work together to complete graphic and check work
Small Group B – Students share what they learn from their lesson and correct their work.
Class – Students contribute to the discussion and clarifications are made.
SUMMARY: Summarize your table so that that will be useful for you.
