This is a transfer task to give students an opportunity to use the three dimensions to make sense of light interactions with objects within a system and between the system and our eyes, causing us to see different things. Students also have the opportunity to demonstrate their understanding of how glass functions in different light situations. For specific guidance, use Portraits Through Glass: Scoring Guidance. Allow students to choose how to share their understanding through written response, pictorial response, or a combination of both.

This is meant to be a summative assessment task for the unit, and it gives you a grading opportunity. The task includes a scoring guide located in Portraits Through Glass: Scoring Guidance. Scoring guides are meant to highlight important ideas students should include in their responses. If students share these ideas elsewhere in the assessment, it is up to you to decide if that understanding is sufficiently demonstrated.
