Rocks (first in series)

Science Objects are two hour on-line interactive inquiry-based content modules that help teachers better understand the science content they teach. This Science Object is the first of four Science Objects in the Rocks SciPack. It provides an introduction to what rocks are, how and where they form, and what we can tell about a rock’s formation by making observations about its characteristics. Different rocks have different compositions (element and mineral assemblages) and textures (grain size, orientation, etc.) Important observations of rock include characteristics of both a sample of the rock and its larger geologic context and natural setting. Observations of rocks can tell us about the processes and the environment in which they formed. The major categories of Earth’s rocks include igneous rock, sedimentary rock, and metamorphic rock.
