Developing and Using Models of Atomic Structure Part 1: What NGSS Looks Like in the Classroom

See students as they work to develop a model of atomic structure. In previous lessons, the students evaluated evidence and decided that the particle nature of matter best explains a range of observations. Now, high school teacher Kristin Mayer helps students use additional evidence from observing a simulation of Thomson’s Cathode-Ray Tube experiment as a source of evidence to inform their models.
Lesson: Unit 1 Investigation 6 from the Interactions Project Curriculum (interactions.portal.concord.org)
This video is 6 of 8 that introduces science teachers to important strategies based on the Framework for K-12 Science Education (sites.nationala...) and the Next Generation Science Standards (NGSS) (www.nextgenscie.... This collection of videos highlights the major shifts in science instruction, explore the new role of the teacher, and demonstrate new instructional strategies in the high school classroom. The project was led by the National Science Teachers Association (NSTA) (www.nsta.org) with funding from Disney, and the video and lesson development was led by CREATE for STEM Institute (create4stem.msu...) at Michigan State University, in partnership with Concord Consortium (concord.org/), and The School of Education (soe.umich.edu) at the University of Michigan.
