Exo and Endothermic Reactions

To Whom it May Concern,

Last week, during class, my team was given the assignment to create a lab. As team leader, I decided the first thing to do, was to find out what would be interesting, or cool. There were various things, most of which were very plausible ideas for the lab. Some of the ideas were luminescence, exothermic and endothermic reactions, something that floats or levitates, and a foaming chemical reaction. After much discussion, we decided on exothermic and endothermic reactions. We plan to accomplish this by using the following chemical reactions,

Mg(s) + CuSO₄(aq) —> MgSO₄(aq) + Cu(s)   Exothermic

3NaHCO₃(s) + C₆H₈O₇(aq)  —> C₆H₅Na₃O₇(aq) + 3CO₂(g)+ 3H₂O(l) Endothermic

Some solutions will have to be made, while the other ingredients are borrowed form the chemistry department. I believe this lab will sufficiently explain the two reactions, and be fun to watch what happens.
