Overview Grade/Subject: 2nd grade Science Geology Experiment - A study of three main kinds of rocks: –IGNEOUS –SEDIMENTARY –METAMORPHIC
Content Standards Earth’s Composition and Structure E2CStudents understand that Earth materials include rocks, soils, and water. E5CStudents understand that the features on the Earth’s surface are constantly changed by a combination of slow and rapid processes Essential Concepts, Skills, and Experiences 3.1 Investigate and describe how the Earth is composed of different kinds of materials. 3.2 Compare, test, measure, record, and describe observable properties of rocks and minerals. 3.3 Describe how the Earth is composed of different landforms.
Introduction Factoid: The whole Earth is surrounded by a crust of rock measuring from 15 to 40 miles (24 to 64 km) thick. What kinds of rocks are these?...
Igneous Igneous or “firemade” rocks come from molten rock, called magma, that lies underneath the Earth’s crust. Magma that reaches the Earth’s surface is called lava. Parts of Oregon, Washington, and Idaho were formed by immense flows of lava. Two most common igneous rocks: Granite and Basalt.
Sedimentary Sedimentary rocks on the Earth’s surface are continually being broken up into small grains through… Weather Running Water Wind Glaciers Gravity When sediment is piled, the weight of the upper layers press down with tremendous force. Limestone and Conglomerate are sedimentary rocks.
Metamorphic Metamorphic rocks form as masses of magma push upward into the Earth’s crust. Sedimentary or Igneous rocks nearby are heated and put under pressure. Heat and pressure may change these rocks to metamorphic or “changed-form” rock. Example: Limestone is changed to marble. Shale is changed to slate.
The Types of Rocks
Have you ever wondered how different rocks are formed? In your journey, you will become a young Geologist through this WebQuest adventure. You will learn how different rocks are formed and understand the process of Igneous, Sedimentary, and Metamorphic rocks! You will also know names of each type of rock!
Student Roles (If working with a partner, take 2 roles each) Gatherer – Responsible for gathering all materials needed for the activity and returning them. Recorder – Records observations made by group and data collected. Time/Task Keeper – Responsible for keeping all students on task and assures experience will be completed in a timely manner. Presenter – Presents the groups findings and conclusion. Responsible for Retelling Task.
Task and Process Task 1: Work with a partner or small group, and use the Internet to explore how the three main rocks are formed. Task 2: Use the Resource List to gather facts from different websites. Task 3: Use the form to record the facts. Task 4: Assess your knowledge by taking the quizzes. Task 5: Complete Rock-Candy Activity Task 6: Retelling task – Present your findings.
