RET Teaching Module 11: Paint Thin Films

Overview

After completing this module, student should be able to: determine a relationship between the thickness of a film and one other variable of their choice, and will be using geometric concepts to determine the thickness of a film. Students will be spinning a known volume of paint onto a substrate, which will be a type of paper product. They will then approximate the film as a regular polygonal prism, and approximate the base area with a regular polygon. Then, using the formula V = B x h, assuming the film is uniform, they can determine the thickness, or height, of the film. Students will do this for three different independent variables, including but not limited to: spin speed, spin time, paint type, paint color, substrate type.

After completing this module, student should be able to:

• Use volume formulas for cylinders, pyramids, cones, and spheres to solve problems
• Use geometric shapes, their measures, and their properties to describe objects (e.g., modeling a tree trunk or a human torso as a cylinder)
