In this lesson, students will explore diffusion through a selectively permeable membrane.

• Students will define diffusion and osmosis.
• Students will describe the process by which particles of matter can or cannot move through different materials.

• diffusion
• membrane
• permeable and selectively permeable
• osmosis
• passive transport
• active transport

By using a simulation, students will explore the concept of diffusion through a selectively permeable membrane.
As a result, students will:

• Conduct experiments related to diffusion and osmosis in a range of settings.
• Define diffusion and osmosis.
• Describe the process by which particles of matter can or cannot move through different materials.
