|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 this Lab-Aids Molecules of Life kit, students study the chemistry of carbohydrates, fats, and proteins. Durable, color-coded plastic atoms can be 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.
• Construct models of carbohydrates, lipids and proteins
• Study isomerism
• Construct part of a starch molecule
• Build models of alcohols and fatty acids comparing them to their structural formulas
• Construct four representative amino acids and a protein
