Lesson Plans and Worksheets
I have found Lesson Planet to be an invaluable adjunct to the scope and sequence my district follows. I have used many of the worksheets as homework to reinforce what I have already gone over in class and to help students gain additional confidence on some of the more challenging lessons.

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 experiment with crystals and polymers and examine their roles in food science.
Students explain what a polymer is and observe and compare the properties of a polymer. They describe the relationship between the cross-linking of molecules to make a polymer, then explore common uses of a polymer.
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.
Students explore the process of science by studying and analyzing fundamental biological molecules in this introductory activity on molecules. The activity includes a pre-activity worksheet and a question sheet for final, individual assessment.
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.
Students examine how some natural substances are polymers. In this polymer lesson students complete a lab and give examples of a physical change.
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.
