Today was the final day of the “Where’s the Evidence?” lab. Students did an experiment where they heated sugar in tinfoil trays and then watched the sugar decompose.
The products of the reaction were charcoal and water. The charcoal appeared as a black residue left behind at the bottom of the tray. The water appeared as steam bubbling out from the warming sugar. This led to interesting conversations about chemical reactions, the four clues, and even the temperature of the resulting water molecules.
