Free 10th Grade Biomolecules Lesson Plan

Topic: Biomolecules

Objectives & Outcomes

• Students will be able to recognize the major categories of biomolecules such as carbohydrates, lipids, proteins and nucleic acid.

Materials

• Handout with information about the major categories of biomolecules (carbohydrates, lipids, proteins, nucleic acid)
• Pencils and paper for each student

Warm-up

• Begin the lesson by asking students what they know about biomolecules. Write their answers on the board.
• Ask students if they can name the major categories of biomolecules. Write their answers on the board.
• Explain that today we will be learning about the major categories of biomolecules: carbohydrates, lipids, proteins and nucleic acid.

Direct Instruction

• Show the students the pictures of biomolecules and ask them to identify which category each belongs to.
• Once the students have identified the categories, explain the basic structure and function of each type of biomolecule. For example, carbohydrates are made up of sugar molecules and function as an energy source for the body. Lipids are fat molecules and function as a source of energy, insulation, and cell-membrane components. Proteins are made up of amino acids and function as enzymes, hormones, and structural components. Nucleic acid is made up of nucleotides and functions as the genetic material.
• If time permits, have students work in small groups to research and present on a specific type of biomolecule.

Guided Practice

• Have the students work in pairs or small groups to classify a series of unknown objects as being either a carbohydrate, lipid, protein, or nucleic acid.
• As a class, discuss the reasoning behind each classification and how the unknown objects fit into the overall category of biomolecules.

Independent Practice

• Provide each student with a worksheet containing pictures of various objects related to biomolecules. The students must use their knowledge of the properties and characteristics of each biomolecule to classify the objects.

Closure

• Ask the students to share one thing they learned about biomolecules during the lesson.
• Review the main categories of biomolecules and their properties.

Assessment

• Observe the students during the guided practice activity and give feedback on their understanding of the main categories and properties of biomolecules.
• Evaluate the group presentations for understanding of the topic and their ability to communicate their findings.
