This demo demonstrates the greenhouse effect by comparing the air temperature of a room with the air temperature inside a clear plastic bag containing black construction paper. The bag models the Earth’s atmosphere and the black construction paper models Earth’s dark surface.
This demonstration/activity involves the safe production of oxygen, hydrogen, and carbon dioxide gases, as well as the appropriate results for tests used to identify these gases. read more
