In this Seminar, Mr. Kessler shared lessons and activities from the first chapter of, a web-based resource that helps teachers engage middle school students with chemistry concepts.

This was the first presentation in a series of six web seminars covering each of the six chapters in During the program, Mr. Kessler introduced participants to the website and explained the format of the activity-based lessons. He then delved into the big idea for Chapter 1: Why are different substances solid, liquid, or gas at room temperature? Participants learned strategies for implementing the lessons by watching several videos and animations featuring demonstrations of each concept. Mr. Kessler also discussed the connection between the lessons and the National Framework for Science Education.
