Rocks: Environments of Formation

Science ObjectDigital resources are stored online in your NSTA Library.

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 second of four Science Objects in the Rocks SciPack. It provides an in-depth exploration of the conditions and environment required during the formation of igneous, sedimentary, and metamorphic rocks. Igneous rock forms from the cooling and crystallization of magma. Sometimes the magma reaches Earth’s surface and cools quickly; sometimes it does not reach the surface and thus cools slowly. Rocks at Earth's surface are subjected to processes of weathering and erosion, producing sediments as they are broken down. Sedimentary rock is formed when sediments are buried and solidified through various processes. Sedimentary rock buried deep enough may be transformed into metamorphic rock or melted down to magma. Rock formed deep within the crust (either igneous or metamorphic) may be forced up again to become land surface and even mountains by the forces that drive the motion of Earth’s plates. Subsequently, this new rock too will erode.

I am so glad I found this science objective. I am a future ECE educator and I want to be able to expose my students to different things. Rocks are my weakest content area and I feel so lucky to have found this object on rocks. The language they use and the pictures are very understandable. YEAH!!!!

I found this SciPack extremely informative. It goes in to great detail about what the different types of rocks are, the way they are formed, and the cycles that these rocks can go through. The visual examples that were provided in this SciPack were very helpful. If you are looking to educate yourself on rocks this is a fun resource to use.

This resource will help you practice your own rock classification skills and think of ways you can encourage your students to do the same.

I really enjoy Science Objects. In 1-3 hours, the Rocks: Environments of Formation Science Object will help me re-learn, refresh, or learn for the first time some critical science concepts I will have to know to obtain my Science Educator credentials. I appreciate that I can complete them at my own pace, and that, if used as park of a SciPack, I have access to a content expert to go to for help. The NSTA Learning Center Science Objects are very beneficial! Not only will they enrich my teaching, the knowledge will enrich my life.

This turned out to be a good refresher course of the rock cycle.

Great resource that clearly distinguishes among igneous, sedimentary, and metamorphic rocks (including how each can be formed). From rocks forming at the surface of the Earth to those forming underneath the Earth, this Science object is very engaging; I love the pictures and videos, and the quizzes help viewers to check their understanding at various stages (as opposed to simply waiting until the end). Nice material to share with scholars either in small groups or at stations (very self-guided/paced).

This science object gave me tremendous insight into the formation of igneous, sedimentary and metamorphic rock. I was able to take information from this resource and roll it directly into my lesson plans; I have also come back to the resource to search for new information to augment my lesson! Another great advantage to having access to these NSTA resources!

This was a great module and it was simple to use. It was just a little boring!

This object is a good resource for teachers to learn more about rocks, but since it is a lot like reading from a textbook, it is not a great student resource. I like the idea to have a school-wide rock gallery. Students bring in rocks after summer vacation each year, and special samples (like volcanic rock from Hawaii) are put on display.
