This is the activity that we completed prior to the NanoRoughness MEA. This activity helps us think about how and why we define roughness on the macro scale. After this activity we introduce the NanoRoughness MEA, where we think about defining roughness on the nanoscale for the established context.
This includes 2 attachments: 1. a document for student teams to fill out about roughness and 2. a couple PowerPoint slides introducing the activity.
(Remember that we introduced this in Day 1 of the Training, so you can also refer to "Day 1 Training" presentation for slides on how to introduce the sandpaper activity.)
