Objective

The objective of this lesson is to introduce the concept of homeostasis and its importance in living organisms.

Standards

This lesson aligns with the following standards:

• Next Generation Science Standards: HS-LS1-3
• Common Core State Standards: CCSS.ELA-LITERACY.RST.11-12.2

Materials Needed

• Whiteboard and marker
• Presentation slides
• Handouts
• Access to the internet for research

Anticipatory Set

Teacher will start with a discussion on what students know about how the human body works. Students will be asked if they have ever considered how we maintain a constant internal environment, despite changes in the external environment.

Direct Instruction

Introduction to Homeostasis

• Homeostasis is the ability of an organism to maintain a stable internal environment.
• Discuss the importance of homeostasis in living organisms and how it helps maintain life.
• Provide examples of how the human body uses homeostasis to maintain equilibrium, such as body temperature regulation.

Homeostatic mechanisms

• Introduce the concept of feedback loops and how they contribute to homeostasis.
• Discuss how feedback loops work to maintain a stable internal environment.
• Provide examples of negative and positive feedback loops in the human body.

Examples of homeostasis in action

• Invite students to research examples of homeostasis in living organisms.
• As a class, discuss the examples and identify the feedback loop involved in maintaining homeostasis.
• Examples can include osmoregulation, thermoregulation, and pH regulation.

Guided Practice

Students will be given handouts with scenarios where homeostasis is disrupted. In groups, students will discuss the feedback loop that would be involved in restoring homeostasis.

Independent Practice

For homework, students will be tasked with researching a specific example of homeostasis and creating a presentation to share with the class.

Closing

To conclude the lesson, students will share their presentations with the class. The teacher will review the key points of the lesson and encourage students to think about how homeostasis affects their daily lives.

Assessment

Formative assessment will include class discussions and group activities. Summative assessment will be based on the quality of the homework presentations.
