Chemistry is doing their first real lab. Chemicals, goggles, glove, the works. Its a simple one because inspite of law and policy, they have never done a lab before. The lab is designed to let them practice an actual lab. They mix chemicals in a baggie and wait for a reaction. This way even through the bag and gloves they can feel a temperature change along with watching for bubbling and color change.
The first set nothing happens, its a control to let them see what one powder does in water. The second one, the powder dissolves into the water and heats it up. The expression on their faces when they realize what is happening. "its hot..."...
buddy "what?"
"really here feel."
buddy feels bag too and passes bag to rest of the group as they feel the exothermic reaction.
Students together..."what happens in the next one?" to me
Me as I walk away to check on other groups. "guess you better find out."
Hear voice behind me..."okay we need 2 tablespoons of calcium chloride."..they are setting up the next test.
