Jewish Education Center of Cleveland Israel Through the Lens of Science This Is Your Life Eugenia Johnson-Whitt This is Your Life Summary: This unit helps students become knowledgeable about the three major classifications of rocks and their relationships in the rock cycle. Students learn about the properties of Israeli and Cleveland minerals and the rocks that they constitute and how to use characteristic properties to identify minerals. They learn and compare the composition of both Cleveland and Israeli geological environments. The latter will have specific focus on the Beit She’an region, Cleveland’s Partnership 2000 area. Students will learn that if one knows how to read a rock it has a story to tell. This unit will provide an introduction into the kinds of stories rocks can tell. Originally Developed for: Grades 6 What Ohio State Academic Standards does this curriculum address? Science Standards: o Describe the rock cycle and explain that there are sedimentary, igneous and metamorphic rocks that have distinct properties (e.g., color, texture) and are formed in different ways. o Explain that rocks are made of one or more minerals. o Identify minerals by their characteristic properties. o o o o o o o Describe that in a physical change (e.g., state, shape and size) the chemical properties of a substance remain unchanged. Explain how decisions about the use of products and systems can result in desirable or undesirable consequences (e.g., social and environmental). Describe that chemical and physical changes occur all around us (e.g., in the human body, cooking and industry). Choose the appropriate tools or instruments and use relevant safety procedures to complete scientific investigations. Distinguish between observation and inference. Explain that a single example can never prove that something is always correct, but sometimes a single example can disprove something. Describe why it is important to keep clear, thorough and accurate records. Integration with Social Studies Content Standards (as appropriate) o Place countries, cities, deserts, mountain ranges and bodies of water on the continents on which they are located. o Use coordinates of latitude and longitude to locate points on a world map. o Describe ways human settlements and activities are influenced by environmental factors and processes in different places and regions including: o Bodies of water 2 Rocks.doc page 1 Jewish Education Center of Cleveland Israel Through the Lens of Science o o o o o This Is Your Life Eugenia Johnson-Whitt Landforms Climates Vegetation Weathering Seismic activity Integration with “Social Studies Skills and Methods” (as appropriate) o Analyze information from primary and secondary sources in order to summarize, make generalizations, and draw conclusions o Organize information using outlines and graphic organizers o Read and interpret pictographs, bar graphs, line graphs, circle graphs, tables and flow charts o Communicate a position on a topic, orally or in writing, and support the position with evidence o Work effectively to achieve group goals: o Engage in active listening o Provide feedback in a constructive manner o Help establish group goals o Take various roles within the group o Recognize the contribution of others As a result of this curriculum, what enduring understanding will the students attain?

Sediments moved and deposited by rivers into coastal trenches or basins are formed into sedimentary rocks. Sedimentary rocks are formed from pieces of other rocks; igneous, metamorphic or sedimentary. Igneous rocks are formed from cooled magma from volcanoes and intrusions (ex: granite, lava, and pumice). Metamorphic rocks are formed from heat and pressure on pre-existing rocks. Progression from one form to another is called the Rock Cycle. Topic questions How are sedimentary, igneous and metamorphic rocks formed? Are rocks formed in Cleveland the same way as those in Israel? How are sedimentary, igneous and metamorphic rocks different and the same? How do climate, location and process impact the composition of rocks? Learning activities 1. Show a rock from Israel and one from Cleveland. Ask students how the rocks are different and alike; make a list on the board. Make sure each student has one rock and a copy of Resource Sheet 1. Students may obtain their rock in any number of ways: Found on a hike or caving trip Provided in JECC kit Brought to class from his or her backyard Provided from a classroom collection Using their rock, have students fill out Resource Sheet 1. Remind them to make detailed observations and list as many properties of the rock that they can. Log on to http://www.geoahead.com/petrology/identifyrock.cfm and use the rock identifier to try and find out what kind of rock they have found. 2. Create a K-W-H-L chart with the class to determine what students know about rocks; see Resource Sheet 2 for a model. They should use information from their rock exploration in the first activity as well as what they generally know. Lead a discussion about characteristics of rocks. As the students generate ideas, record them on the board. Have students volunteer ways that the list of characteristics can be organized into categories. Help students understand that what they are doing is called classification. Tell students that characteristics are used to tell different kinds of rocks apart from one another. 3. Give small groups of students a set of ten rocks and minerals, a sheet of paper or Rock Journal, pencil, and magnifying lenses (one for each student). Demonstrate how to correctly use the magnifying lens. Tell students to categorize and label the samples into groups according to one characteristic per grouping. Instruct each group to write down their labels on a piece of paper (answer sheet) without letting the other groups know. 2 Rocks.doc page 7 Jewish Education Center of Cleveland Israel Through the Lens of Science This Is Your Life Eugenia Johnson-Whitt Have each group tour each other’s group and try to guess how they classified the samples. Once a group thinks it knows the answer for a particular group, it may look at the answer sheet. This will allow students to see and identify similarities and differences of the various types of rocks. 4. Have students look at the following site: http://www.geology-israel.co.il/WEB%20PAGE/MAIN%20MENU.HTML. This website shows the geological formations, types of rocks, erosional surfaces, rock failures, geologic structures, and stratigraphy found in Israel. This site will allow students to compare Israeli rocks with Ohio rocks. Show students 3-4 Ohio rocks (e.g. clay, dolomite, flint, gypsum, limestone, sandstone, and shale). Ask students what questions they have about the rocks in Ohio and Israel to add to our K-W-H-L chart? Add to the chart. Have any questions on the chart been answered yet? Questions: o In what ways are Ohio rocks similar to those in Israel? o What seems to be similar or different between the rocks in Ohio and Israel? Five processes that make up the rock cycle. Metamorphism Weathering and erosion (transport and deposition) Cementation Melting Cooling and solidification Metamorphism – Metamorphism is "changed form". This process changes sedimentary, igneous, and metamorphic rocks into new metamorphic rocks. The heat and pressure within the Earth can change mineral content and chemical composition of the rock. 5. Have your students make metamorphic treats. This will demonstrate how, like metamorphism, the heat changes the pre-existing "ingredients" and forms new rocks (treats). For a recipe see: http://www.personal.psu.edu/users/c/l/cll161/insys%20441/meta_act.htm The metamorphic treat will allow students to make a metamorphic rock model. Gather the ingredients and prepare the metamorphic treats. Before students eat them, have them observe their metamorphic treat crystal structure. Have students discuss their findings before recording them in their Rock Journal. 2 Rocks.doc page 8 Jewish Education Center of Cleveland Israel Through the Lens of Science This Is Your Life Eugenia Johnson-Whitt Ask students to think of another way to demonstrate metamorphism. [This can be for homework, or discussed in small groups and demonstrations given by each.] Reinforce with students that a rock formed via heat and pressure is called a metamorphic rock. Show samples of metamorphic rocks and ask students to describe their visual characteristics. Create a chart of these characteristics and post them next to metamorphic rocks. Weathering and erosion (transport and deposition) – The process of rocks being eroded or damaged on the Earth’s surface by rain, snow, wind etc. is called weathering. There are two types of weathering: mechanical and chemical. Mechanical weathering is when a rock is broken into smaller pieces. Chemical weathering is a rock that has changed as a result of a chemical reaction taking place. Erosion is what happens when sediments loosened from weathering are taken from one area to another by gravity, rain, wind, or snow etc. 6. Have students compare weathering of different sized rocks quantitatively and make comparisons. They can make models of weathering and erosion see: http://www.windows.ucar.edu/tour/link=/teacher_resources/shake_edu.html Have students discuss the differences of the two models. Ask students to think of another way to demonstrate weathering or erosion. If time permits allow students to show their suggestions. What if anything happened to the rocks? How can you explain your results? Cementation - Layers in sedimentary rocks form from the weathered products of igneous, metamorphic, or sedimentary rocks. The products from the rock fragments are called sediments. Sedimentary rock is usually created in water at low temperatures and pressures near the Earth's surface. Cementation are sediments that are "glued" together by minerals that precipitate out of water that was between the sedimentary particles when they were buried (ex: calcite and silica). Clastic sedimentary rock forms when rock or mineral fragments (called clasts) are cemented together. Chemical sedimentary rock forms when minerals crystallize out of a solution such as sea water to become a rock (ex: Dead Sea salt). If a container of Dead Sea water was allowed to evaporate in the sun, remaining would be a quarter to a third full container of a whitish residue of salt and other minerals such as magnesium, calcium chloride and bromine, this is called potash. Potash has been extracted in Israel since 1930. In Ohio, limestone is created from the skeletal remains of organisms that are precipitated chemically from saturated calcium carbonate and sea water many years ago. 2 Rocks.doc page 9 Jewish Education Center of Cleveland Israel Through the Lens of Science This Is Your Life Eugenia Johnson-Whitt 7. Obtain materials for students to make their own sedimentary rock sandwich. 1 pita for each student (fully cut in half), jelly, cream cheese, knife, (for spreading), and a plate: Lay a half slice of pita on a plate. Use the knife to spread a layer of jelly on the slice of pita. Add a layer of cream cheese on top of the jelly layer. Place the second half of the pita on top of the cream cheese layer. Have the students observe the series of layers differentiated by texture and color. Show an example of cementation, such as a salt sample from Cleveland’s salt mines and a salt sample from the Dead Sea. Have students compare and contrast the samples in their Rock Journal. Ask students if the rocks from Israel would contain the same sentiments as the rocks in Israel. How could they test their hypothesis? Reinforce with students that a rock being eroded or damaged on the Earth’s surface by rain, snow, wind etc. is called a sedimentary rock. Show samples of sedimentary rocks and ask students to describe their visual characteristics. Create a chart of these and post next to sedimentary rocks. Sedimentary rocks form from loose particles that have been carried from one place to another and redeposit. These rocks usually deposit in a series of layers similar to the layers in the pita sandwich. The layers can be differentiated by the differences in color, texture, and composition. The oldest layer is on the bottom while the youngest layer is at the top. Over a period of time the layers become cemented together to form solid rock. Melting – Since the inside of the earth is very very hot the rock inside the Earth melts and becomes magma (liquid rock). Cooling and solidification – Once the melting magma inside the earth cools, it begins to solidify, making large crystals (intrusive igneous rocks) that reach the surface of the Earth. This is called lava. Lava has small crystal structures (extrusive igneous rocks) due to the hot rock being cooled so quickly. 8. Making rock candy demonstrates crystal formation of igneous rocks. The crystals form when no more sugar can be added to the mixture (it becomes saturated). When there is so much sugar dissolved, the water can’t hold it all. Some sugar will remain insoluble and grow into sugar crystals. Have students make rock candy. See these websites with background information on making rock candy: http://www.exploratorium.edu/cooking/candy/recipe-rockcandy.html http://www.sciencebob.com/experiments/rockcandy.html http://chemistry.about.com/b/a/196422.htm Reinforce with students that lava forms when melting magma inside the earth cools and begins to solidify. The large crystals that reach the surface of the Earth is called lava. Lava has small crystal structures due to the hot rock being cooled so quickly. It is classified as an igneous rock. Show samples of igneous rocks and ask students to 2 Rocks.doc page 10 Jewish Education Center of Cleveland Israel Through the Lens of Science This Is Your Life Eugenia Johnson-Whitt describe their visual characteristics. Create a chart of these and post next to igneous rocks. Categories of rocks: sedimentary, metamorphic, and igneous 9. Tell students to divide into groups of three students each. Give each group 3 sedimentary, 3 metamorphic, 3 igneous rocks and 1 mineral. Let students decide who in their groups will be responsible for each type of rock. Provide a variety of resources about rocks such as field guides, books, computer programs and the Internet. Alternatively, take the class to the school or public library. Using the resources provided, instruct students to investigate the properties of their specific type of rock. Ask students to list up to four properties for each rock. Also have them place each of their rocks in order of when each was probably formed (i.e., to demonstrate the rock cycle). Discuss the properties and the order in which students placed the rocks. Help students understand how rocks are related to each other through the rock cycle. 10. Arrange for students to study and observe rocks from Cleveland and Beit She’an and identify properties that can be used to classify or divide the rocks into groups. To introduce the Beit She’an rocks, ask students if they are familiar with Partnership 2000. Briefly tell them that Partnership 2000 links Jewish communities in North America with regions in Israel to strengthen both communities, as well as Jewish identity and unity. The Jewish Federation of Cleveland has partnered with our sister city Beit She’an. Beit She’an is a town in the process of development located south of the Sea of Galilee. Beit She’an has approximately 20,000 residents. Show students a map of Israel and have them locate Beit She’an. Tell students that Partnership 2000’s purpose is to build people-topeople (Israeli Jews and Diaspora) connections. The rocks that students will be looking at from Beit She’an were gathered for them by teachers who traveled to Beit She’an to make a science connection. Israel examples include: Limestone – Mt. Gilboa, Marl – Jordan Valley Chalk – Yezerael Hills Flint- Jerusalem Hills Ohio examples include: Limestone - Lake Erie Islands Clay – Cleveland 2 Rocks.doc Flint - Flint Ridge Coal - Belmont County page 11 Jewish Education Center of Cleveland Israel Through the Lens of Science This Is Your Life Eugenia Johnson-Whitt 11. Based on what they have learned to date, have students work in groups and create a poster showing the rock cycle processes See website: http://www.teachnetlab.org/ps101/bglasgold/rocks/lesson3rockcycle.htm [This activity can be web-based. If such is desired, see Resource Sheet 3 for student directions.] Characteristics of minerals Minerals are the main components of rocks. Rocks are composed of two or more minerals. (*Minerals are NOT made of rocks). Minerals are made of a single substance whereas rocks are composed of many grains of different substances. Minerals can become exposed within a rock by the natural weathering processes. Minerals have different important properties which can help identify them: Color Streak Luster Hardness Fracture Cleavage A mineral must satisfy five conditions: 1. A mineral must have definite composition. 2. A mineral must have crystal structure. 3. A mineral must have occurred naturally. 4. A mineral must not be made of carbon. 5. A mineral must be a compound or solid element. Topic questions How are minerals formed? Are minerals in Cleveland the same as in Israel? How do climate, location and process impact the composition of minerals? Learning activities 12. Gather samples of rocks with and without visible mineral crystals. [Another option is to find a necklace with visible mineral crystals.] Ask students to observe the sample and record their observations. Ask the class, “Is there a difference in the samples? If so, what?” Explain the observable differences between the samples. Ask the class to hypothesize, “What is the difference between a rock and a mineral?” 2 Rocks.doc page 12 Jewish Education Center of Cleveland Israel Through the Lens of Science This Is Your Life Eugenia Johnson-Whitt 13. Have students look at the mineral lesson online at: http://volcano.und.nodak.edu/vwdocs/vwlessons/lessons/Minerals/Minerals1.html. Then have them answer the questions on the Mineral Sheet (See Resource Sheet 4). 14. Enrichment option: Invite a geologist to visit your classroom 15. Create lab stations, each with a rock kit (Purchase at Science Kit; contact 800-8287777 www.sciencekit.com (Fax) 800-828-3299) or use the following: Four unknown minerals One hammer Covering cloth Diluted acid Scratch plate Glass plate Penny Steel nail Identification key Goggles Instruct students to try and identify their unknown minerals using the tools available at their stations. Circulate around the room to make sure that students are using appropriate safety techniques and that they are interpreting the properties correctly. Provide Resource Sheet 5a and 5b for students to record their lab results. Have students test for hardness and softness of minerals. See website http://www.geotech.org/survey/geotech/mineral.html or http://www.sdnhm.org/kids/minerals/howto-hardness.html. Have students study the chart to determine the hardness and softness of their samples. Have students calculate the density and specific gravity of the minerals. For testing of specific gravity see: http://www.minerals.net/resource/property/sg.htm). To find their mineral, have students look at the website http://www.uky.edu/KGS/coal/webrokmn/pages/mintype.htm . Inform students that the minerals should be retested if there are any discrepancies. As a class, have each group report on any minerals identified with certainty, and discuss any minerals with unique properties. When the labs are done, ask students place all information in their Rock Journals. 16. Distribute samples of obsidian (or a similar rock with visible mineral crystals) to groups of students. Have students write a paragraph in their Rock Journal describing 2 Rocks.doc page 13 Jewish Education Center of Cleveland Israel Through the Lens of Science This Is Your Life Eugenia Johnson-Whitt their observations. Then, have students work in pairs to compare and summarize their descriptions. Instruct each pair to write its summary on the board. Then, as a class, come to consensus on a good general description of the obsidian rock. Have students use the knowledge they accumulated about this rock to create a working definition of the word “rock” and record in their journals. This is also a good time to revisit the K-W-H-L chart. 17. Distribute a sample of gneiss and a sample of sandstone (or other metamorphic and sedimentary rocks). Repeat the procedures listed in Activity #16 above. If students add or delete any part of the definition recorded above, make changes in the definition of rock. Have students identify the rocks and the minerals that compose the individual rocks. 18. Review the definition of rock and minerals and be sure students understand that there are many different types of rocks. Ways that humans have used rocks and minerals Topic questions How have humans used rocks and minerals in architecture, medically, or for personal use? Are rocks and minerals used differently or the same in Cleveland and Beit She’an? Does climate affect the types of rocks used for buildings? Which rocks were chosen in the Beit She’an amphitheater? Why? Learning activities 19. Prepare a shoebox for each group of students with the following items: cereal, tarragon spice, spoon, wooden clothespins, scotch tape, plate or cup (pottery), eyeglasses sponge, baby powder, toothpaste, Vaseline and cake mix. Tell the students they need to examine and sort the objects in their shoebox into three piles. Objects with materials Objects that do NOT NOT SURE that contain rocks contain rocks and /or And/or minerals minerals See Resource Sheet 6: 2 Rocks.doc page 14 Jewish Education Center of Cleveland Israel Through the Lens of Science This Is Your Life Eugenia Johnson-Whitt As a class, ask students to explain how they know whether items are composed of rocks and/or minerals. How do we as humans use minerals? 20. Ask the class why they think it is important to study rocks and minerals. List their ideas on the board, and add any other ideas you want to add. Using the following websites print out information and discuss as a group how minerals are used in products and provide information about each. Explain how these resources are used in Cleveland and Israel and if possible show pictures. ISRAEL http://www.britannica.com/eb/article-23087 http://minerals.usgs.gov/minerals/pubs/country/2001/ismyb01.pdf CLEVELAND http://www.ohiodnr.com/geosurvey/pdf/clevtour.pdf 21. Create a list on the board of what students know about the Dead Sea. Inform students that there is a push to close the Dead Sea to visitors, then form a debate team and divide the class into two groups, A and B. Explain to each group that students in group A will gather information on the health related resources the Dead Sea provides for humans and why it should remain open. Students in Group B will gather information on the Dead Sea drying up and discuss why it is important to close it immediately. Offer each group copies of the resources below that fit their position: Dead Sea Health remedies resources http://www.dead-sea.net/ http://www.dead-sea.net/f-healing.htm http://www.deadsea-health.org/new_html/diseases_main.html Dead Sea articles related to it drying up http://www.extremescience.com/DeadSea.htm http://www.american.edu/ted/deadsea.htm http://geology.wcedu.pima.edu/~vzinn/saving.htm http://www.livinglakes.org/deadsea/minerals.htm 22. Show and discuss the rocks in the Beit She’an amphitheater. Analyze photos to identify which class of rocks they represent. How do we know? 23. Show pictures and discuss the city of Scythopolis. Discuss the characteristics of the mosaics and rocks found. What can geologists tell about the rocks by studying the mosaics and rocks? For an extension, create a pattern for a mosaic floor (much line a coloring page book) and give each area of “color” certain specifications, for example: a. Stones from all stages of rock cycle (list each one separately) b. Stones with different hardnesses 2 Rocks.doc page 15 Jewish Education Center of Cleveland Israel Through the Lens of Science This Is Your Life Eugenia Johnson-Whitt c. Stones with and without minerals In this case, rather than coloring in the page, students write into each section a rock or mineral name that fits the given definition. For example, in a spot labeled sedimentary, students might write sandstone. 24. Study the Cleveland Salt Mines and have students discover how salt is processed. See website: http://www.wcpn.org/news/2001/01-3/0301salt- mine-2.html. Ask students to compare the usage of Cleveland’s Salt Mine to the Dead Sea. Unit Extensions: Plan field trips to see rock formations, glaciation and rock samples. Plan virtual field trips and locate websites to explore the rock cycle. Have students investigate careers involving rocks, e.g., archaeologist, geologist, natural history museum personnel, jewelry maker. This experience could include speakers. Final Assessment: Ask students if they are familiar with the 50’s show entitled “This Is Your Life” that surprised someone on television and profiled his or her life. Tell students that they have been asked by a Museum of Natural History to produce a geology video or Power Point presentation based on “This Is Your Life” in which geological specimens will be profiled. As a class, discuss what type of scientific information that would be needed about the rock before beginning to create its profile. List the student responses on the board. Suggestions include: What type of rock? (igneous, sedimentary, metamorphic) What are the characteristics? What stage of life is the rock? Where did the rock form? What minerals or other organisms help shape the rock’s life? Divide students into small groups of four students. Allow each group to select one rock sample. Using a standard rock identification kit or make your own (see above), have students investigate and draw conclusions about the identity of their sample. Once students know their sample and have researched their rock’s history (life) have them try to answer the questions created in the prior class discussion. Tell students to be creative and imaginative designing their video or Power Point presentation. Provide final assessment task list on Resource Sheet 6 for student reference. 2 Rocks.doc page 16 Jewish Education Center of Cleveland Israel Through the Lens of Science This Is Your Life Eugenia Johnson-Whitt Resource Sheet 1 (for use with activity #1) Name __________________________________________ Date ________________________ Directions: On the lines provided below, write specific characteristics about your rock.
