Who hasn’t stopped to pick up a pebble, to admire or wonder about its color or texture, or just to toss it in your hand? Rocks speak to us, especially as children, and for some people, like geologists, sculptors, stone masons, and rock hounds, the fascination with rocks lasts a lifetime. Of course rocks can’t really talk, but they can tell us about the history of our rocky planet and its living creatures, if we know where and how to look.
Every pebble we find is part of the geosphere, the rocky covering of our planet. The Earth’s crust is a layer of rock from three to thirty miles thick that underlies Continue reading Rocks and Minerals – Background
FOCUS: Studying rocks helps us to piece together the story of how the geosphere, the Earth’s rocky outer layer, has been shaped and changed over time. We’ll meet some rocks that formed by three different processes, examine some minerals we find in rocks, and look for fossils of ancient creatures. Underlying all the Earth’s land and water, rocks provide a foundation that supports the living world, gives clues about past life forms, and provides us with many materials that we use in our everyday lives.
Introduction: Holding up a rock, ask the children, “What are some differences you notice about rocks? Did this rock start out this small?” Continue reading Rocks and Minerals – Activities

ROCKS AND MINERALS ALIGNMENT WITH
NEXT GENERATION SCIENCE STANDARDS
The activities in this unit help children understand the basic concepts in the Disciplinary Core Ideas listed here. You can use the following list as a guide for lesson planning. These Disciplinary Core Ideas are taken from Grade Band Endpoints in A Framework for K-12 Science Education. Additionally, our activities give children opportunities to engage in many of the Science and Engineering Practices and reflect on the Crosscutting Concepts as identified in the Next Generation Science Standards.
