Question: We already stated the question.
Expectations: What did you expect to happen before we did it? What were the reasons for the expectations?

Match the times and temperatures.
Make a table for the popped kernels: Left in the pan; On the target from 0-20; 20-40; 40-60; 60-80;80-100; 100-120; over 120.

Spend 30-40 minutes: As a whole class watch the video straight through: https://www.youtube.com/watch?v=PhVy1WG_lKQ
In groups discuss the worksheet. You may review the video. Keep the volume low and do not disturb the other groups. Frames-of-Reference-Worksheet
As a group, begin reading: Moving Relatively or Relatively Moving? from The Story of Science by Joy Hakim.
Note new ideas, new words, your questions.
If you finish, examine the following document: http://rfrazier.msblogs.aes.ac.in/files/2013/01/Car-scenarios-3.pdf
We will conduct the popcorn experiment, gather the data, and begin the analysis and the writing of the report.
