Reflection: Developing a Conceptual Understanding What Do Caves and Oceans Have in Common? - Section 1: NGSS Connections and Class Preparation


Which lesson first, the lesson on weathering and erosion that starts to develop a schema regarding erosion based on definitions and images of what it looks like or a hands on discovering lesson where  students explore how flowing water may dissolve and/or erode material.

I chose to run this lab before doing the lesson on weathering  and erosion because I wanted students to have the experience of seeing for themselves what happens when water flows over rock salt and limestone. Then when terms are defined and examples of weathering and erosion are provided students have an experience to attach to these new concepts.

This approach is in line with Project Based Learning.
