Chemistry—A Modeling Approach to Periodicity & Bonding

Leaders: Donghong Sun, Tammy Gwara The periodicity of elements and chemical bonding are essential topics in introductory chemistry. However, when we teach these topics, we frequently rely on anthropomorphizing the particles in order to help students remember: “Sodium wants to lose this extra electron because it’s happier with a full valence.” Students memorize the conventions

Particle Models of Matter for Middle School Science/Meteorology

Leader: Mark Schober Mr. Schober will share a sequence of demos and student activities that induce students to develop a particle model of matter to help them understand meteorological concepts, including wind, air pressure, humidity, and phase changes.
