Description of Workshop: This workshop will focus on how to guide students in developing a key chemistry model, the particle view of matter, from experimental evidence. In the first activity, participants in “student mode” will analyze the data and observations collected from a series of simple experiments on mass conservation. We will then represent both the observable changes and mass change at particle level by drawing particle diagrams. Through presenting results and asking questions to each other, we will develop a explanation of the law of conservation of mass based on a particle model. In the second activity, we will analyze the heating curve (temperature-time graph) of ice derived from experiment to determine how to link observable changes (phase change and temperature change) to particle behavior and the modes of energy storage in the system. Other examples such as the electrolysis of copper(II) chloride and the reaction between iron and copper(II) chloride will be introduced if time permits. In “teacher mode”, we will discuss how the modeling approach promotes students’ deeper understanding of matter and scientific reasoning skills.
Participants will learn about the details of key experiments and will practice interpreting these experiments in preparation for using the experiments with students in their own classrooms. Some of the experiments will be usable in middle school and others in high school science classes.
Questions should be addressed to Fernand Brunschwig <fbrunsch AT gmail.com>.
PhysicsTeachersNYC was originated in summer 2011 by a group of teachers as a teacher-led physics study group. The group members were all practitioners of a curriculum and pedagogy known as Modeling Instruction, developed collaboratively by university and high school physics educators over the past 20 years. PhysicsTeachersNYC connects active physics and chemistry teachers through a GoogleGroup and a website <PhysicsTeachersNYC.org>. PhysicsTeachersNYC is the local alliance of the American Modeling Teachers Association and conducts classroom-oriented professional development workshops on the weekend during the school year as well as intensive 3-week summer Modeling Instruction Workshops. For more info see <PhysicsTeachersNYC.org>. Invitations to upcoming workshops are sent first to members of the GoogleGroup and to others if there is room.

Modeling Instruction. The use of the learning cycle and of modeling in teaching physics was pioneered by Robert Karplus in his textbook, Introductory Physics: A Modeling Approach. Modeling Instruction was subsequently developed at Arizona State University by Hestenes, Wells, Swackhamer, and Dukerich, as well as by many others across the country. The best way to learn about Modeling Instruction is to participate in a workshop, but you can get started by reading <modelinginstruction.org> or Chapter 1 of Introductory Physics by Karplus (at <fernwig.org>; use “guest” for login & password).
