In lesson one of this
program, experiments are conducted on five white "mystery" powders to
determine chemical content and reaction. Salt is fused into a solid block.
By feeding gaseous oxygen into a plastic bag of liquid nitrogen, we observe
the resulting changes in gases; argon condenses into liquid, then turns to
gas upon being removed from liquid nitrogen. Lesson two shows the three
states of bromine. Mercury is evaporated and a match is lit using only
steam. In lesson three, the density of solids and liquids is examined. Gas
densities of copper sulfate solutions, liquid paraffin, carbon
tetrachloride, and dyed propanol are illustrated by layering each substance
in a graduated cylinder. The gas density of a soap bubble is tested with and
without hydrogen; various gas densities are tested to float a hot air
balloon.
