Though this isn't the neatest reproduction of a learning exercise, the exercises in understanding organic molecules are invaluable. In addition to answering questions about the general structure of biomolecules, diagrams displaying a condensation reaction and hydrolysis are provided for learners to assess. You will be happy to add this to your supply of biochemistry assignments.
Chemistry classes pretend to be consultants to a grocery story trying to decide what polymer to use for therir new non-paper bags. They prepare tensile bars and use them to test plastic film samples for strength and stretchability. Both plastic and elastomer are examined. Use this lesson as a hands-on investigation of the properties of polymers.
A lively presentation presents general facts and history of nucleic acids in a note-taking format. Every slide contains colorful photos or graphics to illuminate and engage. Biology aces learn about the function and structure of these essential molecules. After showing this presentation, have them create models of the double helix out of various craft materials.
Students identify that nature polymers like alginate from seaweed and that sodium alginate plus ions creates a slime that they can actually eat. They also identify and interpret that when sodium alginate and calcium acetate when water is added to them. Finally, students identify what the chemical name of their slime is.
After giving basic details about the properties of carbon, some of the common functional groups and molecules are featured. There is some information about specific functions and impact on the human body. The diagrams are helpful and could be used in any individual lesson on this topic. This presentation would also be a great review starter.
Turn your class loose to experiment with the different fat content in skim milk, whole milk, half and half, and heavy cream. This is a visually vibrant experiment, as learners drip food coloring on the surface of the products and measure how far it spreads. The procedure was written up by an education student, so it is not refined, but the activity would be useful in a health class when studying fat content in foods or in a biology class when studying hydrophobic molecules or fats.
