high school chemistry

This 3 hour session provides an introduction to the Assessing for Change in Chemical Thinking (ACCT) professional development series. Session 1 provides an overview of the three program components that drive ACCT sessions: The Chemical Thinking Model, the Formative Assessment Enactment Model and Teaching Dilemmas. Teachers have time to get to know each other and begin to build a collaborative professional learning community. Participants complete a chemistry formative assessment and then explore student work related to that assessment. The Chemical Thinking Framework is discussed in more detail, highlighting the related chemistry practices. The six overarching objectives, the central focus of the ACCT course, are introduced; they will be revisited in each workshop session.

Stoichiometry - A Free Virtual Chemistry Lab Activity

In this virtual activity, a video introduces stoichiometry and guides students to think conceptually using a simple baking analogy. Afterward, stoichiometry calculations connect to the analogy, that are then reinforced with a simple experiment. Finally, students explore a PhET simulation to deepen their knowledge.

In this activity, students learn about the mole. In section 1, students learn what a mole looks like for different substances. In section 2, students learn how the number of protons and neutrons in the nucleus determines the molar mass of an element by comparing individual isotopes in a PhET simulation..
