How does the type of surface affect heating of the air 1 meter above the surface?
This was the research question that students began investigating at the end of September 2011. The investigation began with experiments in class using sand, dry soil, water, gravel, black paper, and white paper. Each material was exposed to light and heat energy from a 60-Watt incandescent lamp for 10 minutes and then allowed to cool for 10 minutes. Temperature measurements were collected at the before heating, after 10 minutes of heating, and after 10 minutes of cooling.
During the first week of October, students collected surface temperature and air temperature data from twelve stations around the school campus.
The following video is an ETV project produced by science students.
