You guys must have had different science teachers in the 6th grade.

I was out sick the day we did stratification of gases & molecular weight, so I have no clue.

6th grade? Not so important. However, undergraduate and graduate degrees in meteorology and work as a research scientist at NASA and the National Weather Service was of some use ;-)
