Today we wrapped up our study of rocks and minerals by exploring some rocks up close.  Each learner brought rocks from home or found some on the playground. We also had some rock and mineral collections to look at from the Brecknock Science Closet.  Learners sketched their rocks, described the color, evaluated the luster and texture, and tested the hardness by scraping them with a nail. We then took a “Rock Walk” around the room to check out everyone’s rocks.
