OverviewOverview
• Grade/Subject: 2nd grade Science• Geology Experiment - A study of three
main kinds of rocks:– IGNEOUS– SEDIMENTARY– METAMORPHIC
Content StandardsContent Standards
Earth’s Composition and StructureE2C Students understand that Earth materials include rocks, soils,
and water.E5C Students understand that the features on the Earth’s surface are
constantly changed by a combination of slow and rapid processes
Essential Concepts, Skills, and Experiences3.1 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.
IntroductionIntroduction• 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?...
IgneousIgneous
• 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.
SedimentarySedimentary• Sedimentary rocks on the Earth’s surface are
continually being broken up into small grains through…WeatherRunning WaterWindGlaciersGravity
• When sediment is piled, the weight of the upper layers press down with tremendous force.
• Limestone and Conglomerate are sedimentary rocks.
MetamorphicMetamorphic• 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.
Have you ever wondered how different Have you ever wondered how different rocks are formed?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 RolesStudent Roles(If working with a partner, take 2 roles each)(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 ProcessTask 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.
