Chemical Reactions
We have been studying the signs of chemical reactions and learning to write and balance the equations that represent chemical reaction. Today, after observing 2 demonstrations that I did showing chemical reactions, the students did a lab where they mixed a variety of chemicals and observed what happened, looking for the signs of a reaction. Following this, they mixed the same chemicals with an unknown chemical. They compared the observations they made of these reactions to their observations from the first set of reactions to determine the identity of the unknown.
