Lesson Plan: Control of Blood Glucose Biology • Third Year of Secondary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe the control of blood glucose by insulin and glucagon as an example of negative feedback.
Objectives
Students will be able to
- recall that glucose is obtained from food in the diet,
- describe how changes in internal environments are detected by the body,
- explain how insulin decreases blood sugar levels in the body,
- explain how glucagon increases blood sugar levels in the body,
- outline how the control of blood glucose is an example of negative feedback,
- suggest what symptoms a person who does not release enough insulin (a diabetic) may have.
Prerequisites
Students should already be familiar with
- the general human endocrine system,
- hormones as chemical messengers transported by the bloodstream.
Exclusions
Students will not cover
