Key Concepts

  • Vitamins are organic compounds essential for bodily functions that the body cannot produce itself.
  • Minerals are inorganic elements essential for bodily functions that the body cannot produce itself.
  • Vitamins are classified based on their solubility in fat or water, affecting their storage and excretion in the body.
  • Specific vitamins and minerals play vital roles in various physiological processes, including immune function, nerve function, and bone formation.

Learning Objectives

  • Students will be able to differentiate between vitamins and minerals based on their composition and origin.
  • Students will be able to classify vitamins as either fat-soluble or water-soluble and explain the implications for storage and excretion.
  • Students will be able to identify the major functions of specific vitamins and minerals in the human body.
  • Students will be able to explain the importance of obtaining vitamins and minerals through a balanced diet.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they already know about vitamins and minerals. Discuss why these nutrients are emphasized in dietary recommendations. Briefly introduce the video and its objectives.
  • Video Viewing (7 mins)
    Play the Khan Academy video 'Introduction to Vitamins and Minerals'. Instruct students to take notes on the key definitions, classifications, and examples provided in the video.
  • Classification & Solubility (10 mins)
    Expand upon the concepts of fat-soluble and water-soluble vitamins. Discuss why fat-soluble vitamins are more prone to overdose. Ask students for examples of each type and why that food is a good source.
  • Function and Food Source Discussion (10 mins)
    Facilitate a class discussion about the functions of specific vitamins and minerals. For example, ask: 'What is Vitamin C essential for? Where do you find Vitamin C?'. Create a table on the board of each function, vitamin/mineral, and food source for each.
  • Wrap-Up (3 mins)
    Summarize the main points of the lesson, emphasizing the importance of a balanced diet for obtaining essential vitamins and minerals. Preview upcoming topics, such as enzyme function and deficiencies.

Interactive Exercises

  • Vitamin/Mineral Matching Game
    Create a matching game where students match vitamins and minerals with their primary functions and food sources. This can be done individually or in small groups.
  • Dietary Analysis
    Have students analyze their own diets for a day or two, identifying the vitamins and minerals they are consuming and areas where they might be deficient.

Discussion Questions

  • Why is it important to consume a variety of foods to obtain all the necessary vitamins and minerals?
  • What are the potential consequences of vitamin and mineral deficiencies or excesses?
  • How do vitamins and minerals contribute to maintaining homeostasis in the body?

Skills Developed

  • Critical Thinking
  • Information Recall
  • Scientific Literacy
  • Dietary Analysis
