  1. Kinetic-Molecular Model Development viaInvestigations in State Changes Molecular behavior of the states of matter Water and Non-Water Behavior

  2. Introduction • Phase changes are a cornerstone of the physical science curricula, and are referenced in almost any physical science text. • Teachers teaching physical science probably address this topic at some point in time during the year, and I believe this unit will help to provide a better conceptual model of molecular behavior. • The primary enhancement over traditional instruction is the use of the VMDL, Water and Universal Simulators to give a visual illustration of abstract, atomic level interactions.

  3. Intended Audience • 9th grade Physical Science course for nearly all incoming freshman. • This is a non-leveled course with integrated skill levels. • The math background of the students varies widely and wildly. • We are going to a 10th grade graduation test in the near future and I believe this unit will : • 1) Enhance student conceptual understanding, and therefore it will help their test performance if the test is developed correctly. • 2) If it does not help their test performance, I would rather positively effect #1.

  4. Placement in the Curriculum • This unit fits directly into existing curricula but changes the format and presentation style of that curricula. • The simulations will be combined with wet labs, and demonstrations toward the development of the concept. • Students who have previously used computers will find their way around the software more easily my students will have also studied elementary ideas about physics and the basic constituents of the atom.

  5. Adjustment & Adaptation • This information is being adjusted to be used with 9th grade physical science students, whose algebra is sketchy at best. • One way to use this unit in a chemistry or honors/AP course would be to address the details regarding the mathematical relationships. • Additionally, the instructor could have the students more specifically articulate the subtle interactions that are indicated by the experiments and the computer models.

  6. Goals, Objectives, Activities, and Evaluation All of the above are expertly tabled on the next slide

  7. Time, Resources, Electronic Equipment, etc. etc. etc. • The unit will take an ordinary amount of set-up, clean-up time with respect to the wet labs and then some time to get to the students to the computer lab or computers to the students. These times should be consistent with your needs and facilities. • I estimate that the entire unit will take about 3 weeks with about one week spent on each goal and corresponding set of objectives and activities. • I envision follow up activities that include explaining the molecular behavior of some common household or community observations. • The wet labs I will be using require no special apparatus or unusual supplies. The biggest issue with facilities and equipment will be access to a classroom set of computers.
