This week we spent time observing different kinds of rocks. 
To figure out what kind of minerals are in of them, we preformed a vinegar test (a weak acid).
We know that Calcite (a mineral) reacts to vinegar by bubbling and fizzing! Therefore, we were testing each one of our rocks (Sandstone, Basalt, Marble, and Limestone) by pouring vinegar on them. If our rock responded to the vinegar, we then assumed it had Calcite in it.
Our room smells like we are dying Easter eggs instead of science!
