Lesson 1.3: Find the Rocks
| Overview | Rocks are all around us. Even in urban areas or built up areas around schools, geologic materials are present -- even if they are not in their natural form. This exercise is targeted towards younger students (Grades 1 - 4), but could serve as a short introductory/reconnaissance activity for further schoolyard mapping activities for older students. Students place the location of rocks on a map of their schoolyard, which could be combined with the previous activity "Navigate your Schoolyard."

| Introducing the Activity |
Rocks are all around us, and they play an important part of our lives. Who knows what people use rocks for? (examples include making cement for buildings, copper for electronic wiring, gold for jewelry, metal for cars, petroleum for fuel, and many more.). Lead students to make sure that they include gold. Why is gold so expensive? Because it's rare -- that means it's hard to find. Today we're going to go out on the schoolyard to find rocks. We probably won't find much gold, but we are going to start looking for all the places that we find rocks.

| Instructions |
Find the rocks (Younger Students) Students should go out onto the schoolyard in a single-file line. Walk the students along a pre-determined route around the schoolyard. Ask them to raise their hands when they locate rocks. Depending upon your class and age group, you can instruct students to write out a one sentence description of where they saw a rock and what it looked like. You can also give students five minutes to roam around the schoolyard on a quest for rocks. If you have bonus points or other incentives, offer them for the student who identifies and describes the most rocks in his or her notebook. Other options include having students sit in one spot and draw a picture of a rock they see. Take a look at the web resources below and read about different building stones and building materials. Be able to take students to a particularly interesting building stone -- even if it is just asphalt on their playground. As them if they can guess about its history. Tell them the process that you think it got there, including the stage that it was at one point underground.

| Closing the Activity |
Students should have enjoyed their trip outdoors and will be particularly wound up upon returning to the classroom. Transition into asking students to describe where they saw rocks. If students used a map, you can project it onto the screen and have students indicate specific locations on the map. Either way, have students describe the locations where they found rocks. Were they all on the ground? Were they all a certain shape? A certain color? Hopefully students will end up by realizing that rocks are all around us in different shapes, different colors, and with different uses. Without rocks, there probably wouldn't be a schoolyard to visit!
|
| Homework | Have students look for rocks on their way home from school and while at home. Have them write a description of the most interesting rock they saw. They should include a description of the location where they found it, what it looked like, and why they liked it so much.

| Further Web Resources |
If you are lucky at your school site, this activity will expose your students to exciting examples of stone building materials. There are abundant web resources about natural stone building materials on the web. We recommend the following general web sites. Global Examples of Building Stones ** Excellent site! General Building Stone Information Activity For trips outside your school site, take a look at these web sites about Urban Geology Walking Tours in your neighborhood. Tours with a ** have explanations of stone buildings that are particularly interesting and might be good background for any area:

California Gr1, Sc4b. Record observations and data with pictures, numbers, or written statements. Gr1, Sc4d. Describe the relative position of objects by using two references (e.g., above and next to, below and left of). Gr2, Sc3. Earth is made of materials that have distinct properties and provide resources for human activities. As a basis for understanding this concept: Gr2, Sc3a. Students know how to compare the physical properties of different kinds of rocks and know that rock is composed of different combinations of mineral Gr4, Sc4a. Students know how to differentiate among igneous, sedimentary, and metamorphic rocks by referring to their properties and methods of formation (rock cycle). Gr9-12, ES3c. Students know how to explain the properties of rocks based on the physical and chemical conditions in which they formed, including plate tectonic processes. |
