This resource is a curated collection of interactives, videos, or other digital media assembled in a conceptually scaffolded 5E lesson format with imbedded formative assessment. It provides alternative or additional tier-one learning options for students learning about the periodic trends, Chemistry TEKS (5)(C). The assignments require student participation with self-checked and teacher-checked formative assessment opportunities. For example, after students record observations and data in their notebooks, they may be prompted to be prepared to share their answers with the class.

Review the resource before assigning it to your students so that you will be ready to review student work as necessary.
