Introduction: Students will be discussing what water sheds are and why they are important to bodies of water. Students will learn that every body of water has a water shed. Students will connect this back to the previous activity discussing pollution within our bodies of water. Students will work in small groups and build a river or lake model showing a water shed and what happens when trash enters the watershed.
Learning outcome:
Students will learn what water sheds are.
Students will identify why water sheds are important.
Students will be able to discuss why watersheds impact our actions with pollution.
Standards:
2-ESS2-2. Map the shapes and types of landforms and bodies of water in an area.
Clarification Statements:
Examples of types of landforms can include hills, valleys, river banks, and dunes.
Examples of water bodies can include streams, ponds, bays, and rivers.
Quantitative scaling in models or contour mapping is not expected.
Inquiry questions:
What is a water shed?
Why are water sheds important?
How does pollution affect the water shed?
Overview of learning experience: Students will be discussing what a water shed is and why they are important. Students will be working together to make their own model of a river or a lake.
Narrative of lesson: Students will watch a video discussing what a water shed is. The students will write the word watershed and the definition in their science notebook. Students will discuss how trash can enter a body of waters water shed then enter the entire the lake or river. The students will work in small groups creating a river or lake model in a tin foil container. They will work together to shower how water flows inside of the container and what will happen if trash is on its water shed. Students will need help throughout this activity while they create their water shed. The groups should be at least three-four students. The students will show their models to their classmates when completed considering it could take two days to complete this activity.
