Creating a Positive Learning Environment for Everyone Be respectful of your classmates Put cell phones in “airplane” mode Turn off tablets Close laptops Save conversation for clicker portions of lecture

Lectures Provide a “big picture” Interactive How do we think about “science”? How do we solve a problem? Interactive Demonstrations and small groups. I expect and encourage questions. Participation expected through clickers.

Everybody Writes 1 The containers to the right all have different argon samples at the same temperature. Select the sample with the highest pressure OR state that all pressures are equal. Explain. 2 Container 1 and 2 each contain equal numbers of particles of ideal helium and neon gas, respectively, both at the same temperature and volume. How do the pressures compare? Explain. Took me 2 minutes to do – need to speed it up or reduce the amount of content on each slide. Possibly omit question 2!

Demonstrations Predict Observe Explain
