Molecules of Life

Molecules of Life Model Classroom Set

Teaching Points

Many introductory biology and biochemistry courses introduce students to the modular approach employed in living organisms, covering various subunits and the mechanism by which they are joined through condensation reactions (dehydration synthesis) to generate macromolecules. Rarely do students get to compare the relative size of the monomers and polymers.

This activity features subunits and polymers of four classes of macromolecules: carbohydrates, lipids, proteins and nucleic acids, as well as water molecules and an ice lattice for comparison. All models are constructed on the same scale, two million (2 x 106) times magnified. A poster allows students to match the subunits with each of the macromolecules and learn about their function. The content of the poster has been duplicated on 5 smaller placemats for use as lab stations.

Requesting Other Models

You may schedule one copy of a model for three weeks. Due to limited resources, we are unable to send multiple copies or additional materials.

If you would like to request a loan of a different model for the same time frame you may add this to your cart. Up to three different types of models may be checked out at one time. You will need to fill out a separate request for model loans with a different time frame.
