Biological Molecules Classification Lesson - High School Biology

It is common practice to teach high school biology students about the major classes of biological molecules - carbohydrates, lipids, proteins, and nucleic acids

Objective

Students will construct a classification system of major biological molecules based on structure and function.

Lesson Plan

The instructor will prepare materials and computers to access Proteopedia for students. As the lesson is implemented, the instructor will facilitate student-to-student dialogue and ask high-level questions as students create their own classification system of biological molecules based on observations of compounds in Jmol. Afterwards, students will compare their classification systems to those which have been accepted by the scientific community.

Preparation

The instructor will print color copies of each of the unidentified sample molecules, making one set of manipulatives per student group. Each group will also have poster paper on which to arrange the samples and create their classification system. A key to CPK coloring shall be provided to students. Computers or laptops will also be provided to students so that they may access the student page on Proteopedia. After the main activity, students will have access to their textbook and other resources. The instructor may assign appropriate chapters of the textbook to students. Prior to the learning segment, students are expected to have a basic understanding of chemistry, including concepts such as bonding, atomic structure, and polarity.

Implementation

Students will gather into groups of no more than four and be presented with color copies of Molecules A-E.

Standards

Common science teaching standards such as the Next Generation Science Standards and the AP Biology Framework support the content and instructional strategies used in this learning segment.
