The Last Supper: Identifying Macromolecules Lesson Overview

The students will solve a mystery using laboratory tests for different types of macromolecules. They will use argumentation to justify and communicate their claim. They will construct explanations and communicate with one another to determine which macromolecule would be best to eat in different scenarios. Students will be able to identify the structure and functions of the four main types of macromolecules. The students will use laboratory testing to determine the identity of an unknown. They will fill in a chart about the structures, functions, and examples for each macromolecule type and then they will practice their knowledge by answering short response questions relating the macromolecules to the real world. Finally, they will review using a whole-class cooperative activity and take a quiz about the structures and functions of macromolecules.

Lesson Components Time Inquiry Skills Tech. Used Engage Level Brief Description
Engage 4 min 5.2 Computer, Projector 2 Students will view a real-time video,, about what happens in the stomach when a person eats. They will then do a rally robin with their shoulder partner to begin thinking about why the video was shown
Explore 15 min 1.3, 2.1, 2.5, 3.1, 3.3, 3.5, 3.7,4.2, 4.3, 5.2, 5.3, 5.4 none 3 Students will use given information to design a and carry-out a procedure to solve a forensic scenario.
Explain 25 min 5.2, 5.3, 5.4, 5.6, 5.7, 6.1, 6.2, 7.2, 7.3 none 3 Students will then use a “claim-evidence-justification” board and a round-robin activity to communicate their findings to the other students in the class.
Expand 30 min 3.3, 3.4, 4.2, 5.8, 7.3 none 3 Students will use available sources to fill in chart about the form and function of each of the four main types of macromolecules. They will answer short response questions relating macromolecules to their use in real life situations.
Evaluate 15 min (part 1), 10 min (part 2) 7.3 none 3 Students will do a whole-class cooperative activity, Test-Test-Swap, to review. Students will take a quiz about the structure and function of macromolecules.

Level of Student Engagement
1     Low     Listen to lecture, observe the teacher, individual reading, teacher demonstration, teacher-centered instruction
2     Medium     Raise questions, lecture with discussion, record data, make predictions, technology interaction with assistance
3     High     Hands-on activity or inquiry; critique others, draw conclusions, make connections, problem-solve, student-centered
