Begin the lesson by discussing the importance of fresh water for life on land. Highlight how streams and rivers are crucial sources of fresh water.

Show a short video clip that introduces streams and rivers, emphasizing their role in the ecosystem.

Explain the difference between streams and rivers, focusing on their size, flow, and the role they play in the water cycle.

Use diagrams to illustrate how streams start at high points and may join to form rivers.

Watch the video 'The World of Freshwater' to understand the importance of freshwater ecosystems and the biodiversity they support.

Engage students in a discussion about the journey of a stream from its origin to where it joins a river.

Conduct a hands-on activity where students create a model of a stream and river using materials like modeling clay and water.

Use the 'Modeling Land and Water' assessment to guide students in observing and describing water flow in their models.

Assign students to research and write a short report on a local stream or river, including its source, path, and significance to the community.

Use the 'Earth’s Water' assessment to evaluate students' understanding of different bodies of water and their characteristics.

Facilitate a class discussion to review the key concepts learned about streams and rivers, and their importance to life on land.

Encourage students to reflect on how they can contribute to the conservation of freshwater resources.

Administer the 'Review – Earth’s Land and Water' assessment to test students' comprehension of the unit.

Encourage students to extend their learning by exploring the 'Earth’s Landforms' assessment, which helps them identify and describe various landforms.
