Biological Macromolecules

Introduction

At the end of the lesson, the learners shall be able to:

  1. Distinguish between carbohydrates, proteins, lipids, and nucleic acids
  2. Summarize the general characteristics of each biomolecule

 

Task

Trapezoidal Tangram

The different puzzle pieces can represent different elements upon which, depending on orientation with different pieces, creates a different pattern or “biomolecule”.

 

 
Process

Cut out puzzle pieces out of thick paper print-outs. You will be grouped in pairs or by three’s and you will form the different shapes using puzzle pieces.

 

 
Evaluation

Show how different configurations or shapes can be formed from identical pieces. Explain how similar it is to macromolecules that are comprised mainly of carbon, hydrogen, oxygen and nitrogen, and yet many different substances are formed, all with varied properties.

Conclusion
