  1. Maintaining Homeostasis Overview Study with this interactive worksheet to learn how our bodies regulate our body temperature to ensure we don’t suffer damage from cold or hot weather. Beside, students can review some key terms used in climate change topics.

  2. Teach your students how the human body systems stay stable using this free worksheet packet on homeostasis. Students will learn how different human body systems work together to keep our bodies healthy.

  3. Introduction: Homeostasis means maintaining a relatively constant state of the body’s internal environment. The term used to describe a pattern of response to restore the body to normal stable level is termed negative feedback.

  4. Give an example of how your body would maintain homeostasis in the following situations: You have gotten cold while sledding and playing in the snow in January. You are exercising by cross-country skilling and need more oxygen for your muscles. You ate a lot of snow and it melted and turned into water in your excretory system.

    This lesson narrative is intended to assist educators in teaching the central concept of homeostasis to entry-level Biology students and includes a kinesthetic game where students will actively engage in learning about the mechanisms that maintain blood glucose levels in humans.

    Homeostasis, negative feedback, stimulus, receptor, integrating center, effector/target organ, hormone, insulin, glucagon, pancreas, glucose, glycogen

    “What does the word “feedback” mean? With what do yo u associate this term?” The teacher will guide a brief discussion on what feedback is. An example would be students receiving progress reports. We will discuss the purpose of progress reports; for students to gauge their performance in there classes. Students will be asked, “What would you c...

    (Materials for this part of the lesson courtesy of Susan Mickey, Salem High School, Salem, MA) Students are given a worksheet with the terms stimulus, receptor, integrating center, effector, and response. They will define these terms based on the analogy of a home heating system. After reading about how a home heating system works, they will iden...

    For homework, students will be instructed to identify the organ systems that are involved in each of the homeostatic processes that were explored in class. For upper level classes, students will be asked to investigate the homeostatic process that governs blood sugar regulation. This can be done in their text book or an outside resource, such a...

    Students will use information gained in the prior lesson in order to understand how the human body regulates blood sugar levels. The teacher will conduct a brief overview of what was learned in the prior lesson. Students will then be asked, “What happens in our bodies after we eat? What type of nutrients/molecules are in those foods?” A list wil...

    The teacher will briefly explain that our cells need a consistent and readily available supply of glucose in order to produce ATP and therefore maintain vital functions. The teacher will show a flow chart of the blood sugar regulation feedback loop, connecting this to the diagrams they generated in the previous lesson. Students will be asked to i...

    Have students return to their desks and write a brief description of the activity they just did. Make a list of their classmates, what role they played, and what task they had to perform.

    What happens when there is too little glucose in the blood? The teacher would now explain how glucagon works in opposition to insulin, in order to maintain normal blood sugar levels.

  5. SC.6.L.14.5: Identify and investigate the general functions of the major systems of the human body (digestive, respiratory, circulatory, reproductive, excretory, immune, nervous, and musculoskeletal) and describe ways these systems interact with each other to maintain homeostasis.

  7. Gizmo Warm-up. To survive, an organism must be able to maintain stable internal conditions in a changing environment. This process is called homeostasis. The Human Homeostasis Gizmo allows you to explore how the human body stays at a nearly constant temperature in different conditions. Notice the Air temp. and Body temp.
