For centers today, we painted with watercolors and salt crystals, had a dinosaur dramatic play center, weighed rocks on the balance scale, wrote magic pebble stories, and tested the hardness of rocks. It was a great center day!
During project work, the kids added sandstone and limestone to their rock collections. They tested vinegar drops on their limestone to see if it would bubble. The vinegar reacts with the calcite in the limestone causing a small bubbles of carbon dioxide. We also made sedimentary rocks using dirt, rocks, and plaster of paris and we made fossils out of salt dough.
