Product Details

Demonstrate the diverse scientific studies encompassing the chemical processes of living things. Essential life processes that may be understood using biochemical principles include cell signaling, energy and metabolism, and genetics. This set of three demonstrations teaches students about the biochemistry occurring in their own bodies.
• pH and Protein Solubility—Examine the effect of pH on the solubility and structure of casein to find its optimum value.
• Digestive Enzymes at Work—Learn how the body transforms the food we eat into essential nutrients needed to carry out cell processes and growth.
• The Floating Catalyst—Investigate the reaction of catalase, which catalyzes the decomposition of hydrogen peroxide in plant and animal tissues.

Includes enough materials to perform each of the above demonstrations three times. This kit also comes with the Flinn ChemTopic™ Labs, Vol. 20, Biochemistry—The Molecules of Life, which contains instructions for four experiments and five demonstrations.

Concepts: Enzyme structure and function, proteins, pH.
Time Required: One class period

Performance Expectations

MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures.
MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-5. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.
MS-LS1-7. Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism
HS-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
HS-LS1-1. Construct an explanation based on evidence for how the structure of DNA determines the structure of proteins, which carry out the essential functions of life through systems of specialized cells.
