## Reflection: Developing a Conceptual Understanding Parts of a Pen and Its Properties - Section 3: Ball Point Pen Diagram One

Use of key to help organize work. Color code information...

While I modeling the diagram, I realized that it would help students to color code the material, property terms, and how the property supports the pen function in different colors, to help students organize their data. I directed students to circle material in a chosen color and property in another color. Then when the labeled their diagram, the label color would indicated whether it was a reference to material or property.

The kiddos liked the idea of using different colors to show different aspects of the pen.

I also noticed that the teams were struggling with describing the property words that may be useful. So I stopped the lab for a moment and asked for material property words that students might use to describe the pen's materials. I wrote their suggestions on the board.
