MU Modeling Chemistry Workshop Day 6a

By | August 15, 2011

On Day 6, we begin to take a quantitative look at energy. We used the LOL charts to describe the qualitative role of energy in phase and temperature changes. While we can’t calculate the amount of energy in each of the accounts initially, or at the end, we can measure the energy entering or leaving [...]

MU Modeling Chemistry Workshop Day 5b

By | August 15, 2011

Energy is an integral part of the modeling curriculum. We began to talk about it a bit in unit two, and will extend the model in unit 3. We started with a discussion of heat vs. temperature (which included viewing a Eureka video): Next, we did a lab (Icy Hot), where we heated a sample [...]

MU Modeling Chemistry Workshop Day 5a

By | August 15, 2011

Lost my flow preparing for ChemED presentation, ChemED itself, #140edu and the subsequent post-PD summer laze, but better Nate than lever! We started Day 5 by discussing an article by Ronald Gillespie¬†that we’d read the night before. The article discussed topics that the author thought should be included in an introductory college chemistry course. ¬†In [...]

MU Chemistry Modeling Workshop: Day 4

By | July 13, 2011

Day 4 was a half day. Pressure Labs After discussing the Gabel article, we reviewed the topic of pressure (in student mode), and brainstormed what factors might affect pressure on the particle level. While some ideas were impossible to test (weather, elevation), we could test temperature, number of particles, and volume. The instructor introduced the [...]

MU Chemistry Modeling Workshop: Day 3

By | July 12, 2011

On Day 3, we discussed our thoughts on Unit 1 materials, and summarized “The Story So Far” on whiteboards without words. Here’s “Team Awesome’s” board: After a Board meeting, we began unit 2. Diffusion Demos The first activity involved opening a fragrant substance (freshly popped popcorn) at a certain location at the room. In student [...]
