Begin the lesson by discussing what pollution is and how it affects our environment. Use simple examples like trash in water bodies to illustrate the concept.

Introduce the topic with a video on 'Water Pollution and How We Can Reduce It!' to show real-life impacts of pollution and ways to mitigate it.

Explain the causes of water pollution, such as trash, sewage, and chemicals, and how they affect aquatic life.

Use the video 'Human Changes to the Environment' to illustrate how human activities impact natural resources and the importance of environmental stewardship.

Engage students in a discussion about the impact of water pollution on living organisms, using examples like sea turtles trapped in plastic.

Watch 'The Problem of Marine Debris' video to explore how marine debris affects ocean ecosystems and discuss actionable steps to reduce it.

Conduct a simple experiment where students simulate water pollution by adding small items (like paper bits) to a clear container of water and observe the effects.

Use the 'How Does Pollution Change the Environment?' worksheet to help students draw and write about the effects of pollution.

Have students create a poster illustrating ways to prevent water pollution and present their ideas to the class.

Ask students to share examples of water pollution they have seen or heard about and discuss how it affects the environment.

Review key concepts about water pollution and its impact on living things. Encourage students to reflect on what they can do to help reduce pollution.

Use the 'Ways to Help the Environment' assessment to evaluate students' understanding of environmental stewardship and pollution prevention.

Encourage students to take the unit quiz to test their comprehension of the topic.
