Rocks are the most common material on earth. But how do we identify and classify rocks? Your mission is to become an amateur geologist by exploring the different types of rocks; sorting them by color, hardness, texture, layering, and particle size; and discussing with your classmates what you learned!

Rock Expert Webquest


The Museum of Natural History is creating a new exhibit on rocks and minerals.  They are looking for expert knowledge to share with museum visitors.  They need your help, Rock Expert!


You will work as an Amateur Geologist for the Museum of Natural History.  You will work to become an expert on the three types of rocks and the rock cycle.  As you learn about rocks, you will fill out the worksheet provided by your teacher, Mr. Williams.  He will be plotting your progress and evaluating your work.  Your class will be divided into groups of three near the end of the period, and you will discuss with your partners what you have learned about the three rock types.


STEP 1:  Put your name on your Rock Expert! handout.

STEP 2:  Use the following websites provided to gain an understanding of the different rock types, the rock cycle, and other interesting facts about rocks.  Make sure you understand how the different rock types are formed, some common characteristics of each type, and some examples of each type.  Use your research form to guide your research.  Note:  You need to cite one other source besides the ones listed below to receive credit for number 5 on the assignment.

STEP 3:  Meet with your expert group to share the information that you have found with each other.  Did someone else find out something that you didn't?

STEP 4:  In your groups, make a Power Point Presentation about the types of rocks.  Make 1 (one) slide about each rock type.  Each slide must contain a Title, at least one image, and Important information about the rock type (such as how the rocks are formed, some common characteristics of the rocks, and some examples of rocks in that rock type).  Please include a title slide.  (This means that there should be 4 slides when you are finished.)  Note:  Save your work often.

STEP 5:  When you are finished with your Power Point Presentations, save your work and print a copy of your slides.  Remember, we DO NOT want to waste paper, so select the option to print 4 slides to a page.  If you need help with printing, let Mr. Williams or Ms. Andersen know.

STEP 6:  Share your presentation and research with your fellow geologists (parents, siblings, friends, neighbors, your pet, or anyone else).


Congratulations!  You are now Rock Experts!  Hopefully, you have gained some new information, and will never look at a rock the same way again.
