Description:

This lesson consists of six demonstration activities that show examples of ways in which water and air absorb heat to transfer energy from one place to another. These demonstration activities act as unique phenomena in which students can generate questions to lead subsequent investigations with each activity in learning centers.  Through gaining content from investigations with these phenomena, students will gain insight into how energy conversions work in a solar updraft tower.

Other Material(s) Used:
pencils, paper, scissors, 4 glass bottles or jars, food coloring, water, a solar bag, a norwegian candle spinner, a lamp w/o shade, needle and string, radiometer
