2004 Summer Workshop (PPT II) (“Light group”)July 12-July 16, 2004, 8:00-3:30July 17, 2004, 8:00-12:00Watanabe 415

Figure out what to buy:1. What WE need for class2. What teachers will take home3. What must be built4. What must be bought

Goals: Educate out-of-field high school physics teachers about physics Test & develop new PPT activities

Objectives: TBD

Daily: Review previous day & turn in homework Lunch (30 mins) Write reflections in journals (no more than 5 minutes after each activity). Those doing a portfolio need to include their journals

in their portfolios. Those not doing a portfolio need to turn in their journals at the end of the workshop. Homework: Activity Feedback Forms for each activity completed that day.

Always need to bring: Attendance sheet Snacks
