FOURTH GRADE ROCK DETECTIVES

We have begun our Earth Science unit.  Here are students completing a rock investigation to find out about the different properties of rocks such as texture, streak, luster, and hardness.  Students also found there is one rock that will float (pumice) and discovered that limestone will bubble when placed in vinegar because limestone contains calcium carbonate.
