This was a great activity from the standpoint of seeing how varying the
amounts of reactant can change the products - change not only HOW much gets
formed, but also WHAT gets formed. And I liked the pH test.
HOWEVER! I have serious concerns about allowing students to eat anything
they've made in the lab. I have a strict rule about no food in the lab and
would not consider breaking that rule even for this activity. I might do
the activity on a smaller scale and observe the results, but not eat them.
I am curious, how did she bake them? Bunsen burners - no way. Maybe a hot
plate or a nearby cooperative home ec teacher? If they went into
dessicating ovens that she uses to dry hydates then certainly her students
should NOT be eating their products!
