Figure out what to buy:

What WE need for class
What teachers will take home
What must be built
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:
