Use the Molecules of Life Placemat and the accompanying models to explore the following concepts:
Each of the structures featured is essential to sustain life.
Large biological polymers are composed of smaller building block
The biomolecules featured on the placemat and accompanying models are magnified 20 million times.
The size of atoms remains constant in all molecules. For example,
oxygen (shown in red) remains the same size whether it is in a
nucleotide, amino acid, starch, phospholipid or water.
Each polymer model has 1 monomer highlighted in green to help your
students see the repeating pattern. For example, the DNA model has 1
nucleotide colored green and cellulose model has 1 glucose molecule
The 3-D molecular models sit on a 24” x 19” laminated placemat that
includes a description of each 3-D structure. The entire set includes 17
spacefill models: 1 DNA, 2 adenosine monophosphate, 1 aquaporin, 2 asparagines, 1 cell
membrane, 2 phospholipids, 1 starch, 1 glycogen, 1 cellulose, 2 glucose,
1 ice structure and 2 water molecules. All models are built to the same scale — 20 million times their real
Models are made of plaster by rapid prototyping and should be handled
with care. Models will break if dropped, held tightly or handled
