Lesson Plan: Carbohydrates Biology

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe the structure of different carbohydrates and outline the roles of carbohydrates in organisms.


Students will be able to

  • state the general formula of monosaccharides as (CHO)2,
  • recall the classification of carbohydrates into simple sugars (mono- and disaccharides) and complex sugars (polysaccharides),
  • describe the alpha and beta structures of glucose and its properties as a hexose sugar,
  • outline the synthesis and breakdown of disaccharides including maltose, sucrose, and lactose,
  • describe the structure and function of glucose, starch, glycogen, and cellulose,
  • explain the role of monosaccharides in the processes of transferring energy inside the cells of living organisms.


Students should already be familiar with

  • the fact that carbohydrates are an essential nutrient in the human diet,
  • the fact that carbohydrates provide energy for an organism,
  • carbon and hydrogen as elements found in organic molecules.


Students will not cover

  • testing for carbohydrates using Benedict's reagent or iodine.
