Standards: HS-PS1-1 — Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms. HS-PS1-3 — Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles. HS-PS2-6 — Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.

Resource type: Phenomena-Based Lesson – Teacher Discussion Guide. Format: editable Microsoft Word file plus a ready-to-print PDF.

Classroom use: Open with the phenomenon slide show, let students record ideas on the response sheet, and lead the discussion with the teacher guide. Built for high school Chemistry, grades 9–12.
