Full lesson	Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle}

Lesson Plan: Active and Passive Transport & Osmosis

Topic

Active and Passive Transport and Osmosis

Subject

Biology

Grade/Age Group

Middle School / Grades 6-8

Objectives

• Understand the difference between active and passive transport.
• Explain the process of osmosis and its significance in living organisms.
• Identify examples of active and passive transport in biological systems.
• Assess the influence of concentration gradients on transport processes.

Materials

• Whiteboard and markers
• Projector and presentation slides
• Diagrams of cell membranes
• Osmosis and diffusion experiment materials (e.g., selectively permeable bags, sugar solution, water)
• Handouts summarizing key concepts
• Exit tickets for assessment

Length of Lesson

30 minutes

Lesson Structure

Step Number	Step Title	Length (minutes)	Details
1	Introduction to Transport	5	Briefly introduce the concepts of transport in cells. Discuss the importance of transport for cellular function.
2	Active Transport	10	Explain active transport, its definition, and examples. Use diagrams to illustrate how molecules move against a concentration gradient.
3	Passive Transport	5	Define passive transport and differentiate between types (simple diffusion, facilitated diffusion). Include examples.
4	Osmosis	5	Explain osmosis as a specific type of passive transport involving water. Demonstrate with a simple experiment using selectively permeable bags.
5	Class Discussion	3	Facilitate a discussion on real-life applications and implications of these processes in health and disease.
6	Exit Ticket	2	Distribute exit tickets where students write down key points learned and one question they still have. Collect them for assessment.

Assessment

• Informal assessment through class participation during the discussion.
• Review exit tickets to evaluate understanding and collect feedback on the lesson.

Homework

• Assign a worksheet that includes questions and scenarios relating to active and passive transport and osmosis.
• Homework will be checked for understanding but will not require students to present their answers in front of the class.

Alignment with National Curriculum

This lesson aligns with the Next Generation Science Standards (NGSS) focusing on cellular processes and interactions. It meets the expectations for understanding life sciences by exploring key biological concepts related to cellular function and transport mechanisms.
