In this lesson bridging art and science, students build understanding of the terms translucent, opaque, and transparent, as they apply to cloud descriptions, and create a collage using materials matching these characteristics, as well as a powerpoint of cloud images having a range of optical property. There are two activities in this lesson. The resource includes a scoring rubric, teaching notes, and a vocabulary list linked to a glossary. This activity is related to the NASA CERES Students Cloud Observations Online (S'COOL) project.
