Molecules of Life

Scientific Concepts and Processes

• Build 3-dimensional models of carbohydrates, fats and protein
• Develop a basic understanding of carbohydrates, fats and protein
• Determine the molecular characteristics of carbohydrates, fats and protein
• Study isomers
• Build a simple starch molecule by dehydration synthesis
• Compare molecular models to structural function
• Understand the structure and function of carbohydrates, fats and protein in relation to the chemical processes of the human body

What are the molecules of life? Science has proven that atoms unite into molecules, and that when molecules exchange atoms, new substances are created. Inorganic substances such as water, carbon dioxide, and oxygen, together with organic substances such as carbohydrates, lipids, and proteins, make the protoplasm found within the cells of living organisms. The molecules of life are the molecules that make protoplasm.

In the Complete Molecules of Life kit, students study the chemistry of carbohydrates, fats, and proteins. Durable, color-coded plastic atoms are assembled, disassembled, and reassembled quickly and easily into 3-D molecules that provide highly graphic and extremely motivating learning experiences.

Carbohydrates, lipids, and proteins can be completed as a series of lab activities, or as separate units. Students can also work independently for enrichment or remedial study. Each module can be systematically subdivided into smaller sections so students can do the work when most appropriate.

The complete Molecules of Life kit includes twelve packets of color-coded molecular model components, an instruction manual, and three reproducible worksheets, one for each module. Enlarge-a-Lab contains one additional packet of components.
