The teacher will present an informational text from the website, ReadWorks. The students and teacher can interact with this non-fiction text by annotating the text digitally. The students will answer the questions associated with the article as an assessment. This learning activity can be used as an introduction to transparent, translucent, opaque, and reflective materials, serve as reinforcement after students have already learned these concepts, or be used as an assessment at the conclusion of a lesson. This informational text could provide background knowledge before students investigate materials that are transparent, translucent, opaque, or reflective.
