The first experiment we did was to heat up Sodium Chloride, and observe its appearance at first, than during heating, after heating and after cooling.
Sodium Chloride was grainy and white in color. After heating, (for a very, very long time), it melted into a colorless liquid. When we removed it from the heat source for just awhile, the liquid form of NaCl change state back into liquid and it was a little foamy.
The coolest one that we saw was Magnesium oxide. It sparked of a bright white light when it was heated! It was really cool.
Heating the Magnesium...
and the white bright light
