Knowledge

Students know:
  • Minerals make up rocks.
  • Rocks are formed in many environments upon and within the Earth's crust.
  • Igneous rock is formed by the cooling of magma inside the Earth or on the surface.
  • Sedimentary rock is formed from the products of weathering by cementation or precipitation on the Earth's surface.
  • Metamorphic rock, is formed by temperature and pressure changes inside the Earth.

Skills

Students are able to:
  • Construct an explanation that includes specific cause and effect relationships for formation of each type of rock.
  • Identify and describe evidence to construct an explanation such as cooling of magma at different rates form various types of igneous rocks, cementing of materials together or precipitation to form different sedimentary rocks, and pressure and temperature changes within the crust and upper mantle to form metamorphic rock.
  • Use reasoning to connect the evidence to explain transformation of rocks in the Earth's crust.

Understanding

Students understand that:
  • Earth is a complex system of interacting subsystems: the geosphere, hydrosphere, atmosphere, and biosphere.
  • The geosphere includes a hot and mostly metallic inner core: a mantle of hot, soft, solid rock: and a crust of rock, soil, and sediments.
  • Solid rocks can be formed by the cooling of molten rock, the accumulation and consolidation of sediments, or the alteration of older rocks by heat, pressure, and fluids.

Assessment Strategies

Open-Ended Questions: 

1. Write a 5 sentence paragraph (in the space below) about what you have learned about the rock cycle from this activity. POSSIBLE ANSWERS: (1) metamorphic rock formation (2) sedimentary rock formation (3) igneous rock formation  (4) intrusive vs extrusive (5) characteristics of rock identification (6) lava vs magma (7) rock cycle etc… Students should have complete sentences.

2. Sketch a quick rock cycle (in the space below) including the 3 rocks and the 3 processes that dictate their formation. POSSIBLE ANSWER: http://sci.gallaudet.edu/Mary/Rockcycle.html

Quiz: (choose 5-10 questions from the activity and develop a quick quiz)

 1) What are the three types of rocks that are part of the rock cycle? POSSIBLE ANSWER: igneous, metamorphic, and sedimentary

2) What do you need in order for an igneous rock to form? POSSIBLE ANSWER:   weathering and erosion  

3) What does erosion have to do with the rock cycle?  POSSIBLE ANSWER: without erosion there would be no sedimentary rock formation and thus effecting metamorphic and igneous rock formation

4) What is the difference between magma and lava? POSSIBLE ANSWER: magma is underground and lava is above ground

5) When metamorphic rock melts what does it form? POSSIBLE ANSWER: magma

6) What can you infer about metamorphic rocks from their name? POSSIBLE ANSWER: meta- means after or beyond and morph- means to change or transform.  Thus metamorphic rocks means a rock that has changed or transformed from another rock after something happened to it.

7) How are metamorphic rocks formed? POSSIBLE ANSWER: from igneous or sedimentary rocks that have undergone high heat and pressure

8) What has to happen to sediment in order for it to form sedimentary rock? POSSIBLE ANSWER: compaction and cementation

9) List an example of a sedimentary rock. POSSIBLE ANSWER: breccia, conglomerate, sandstone, siltstone, and shale

10) When does a sedimentary rock become a metamorphic rock? POSSIBLE ANSWER: when sedimentary rocks have undergone high heat and pressure

11) What is deposition? POSSIBLE ANSWER: Deposition is the geological process in which sediments, soil, and rocks are added to a landform or land mass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.

12) Where are extrusive igneous rocks formed? POSSIBLE ANSWER: Extrusive igneous rocks form when magma reaches the Earth's surface a volcano and cools quickly. Most extrusive (volcanic) rocks have small crystals.  

13) Where are intrusive igneous rocks formed? POSSIBLE ANSWER: Intrusive, or plutonic, igneous rocks form when magma cools slowly below the Earth's surface. Most intrusive rocks have large, well-formed crystals.

14) What is the process of the rocks changing from one form to another called? POSSIBLE ANSWER: the rock cycle

15) What are the two types of igneous rocks called? POSSIBLE ANSWER: extrusive and intrusive

Writing: 

Write a story about the rock cycle from a rock's perspective. (Ensure you give the students guidelines on what vocabulary you would like used and how long it should be.) POSSIBLE ANSWER: Students may create their storybook on the website: https://www.mystorybook.com/

Variation Tips

The teacher may consider doing this activity as a whole group where they follow the activity on the smart board instead of individually working it. I have had success with this process when the ability level of the class is not high enough to let them work on their own. Also, you can split a varied class into working as a small group with you and letting the more advanced students work ahead.

Students may create their storybook on the website: https://www.mystorybook.com/

Background / Preparation

Please click link to handout of activity.       code: earth

The teacher needs to make sure each person or group (2 people) have a copy of the Rock Cycle Webquest activity instructions prior to the start of the activity.

The teacher also needs to make sure all students/groups have access to a BYOD or classroom device that can access the internet.

Part 2 may require the teacher to print off the rock cycle for the students (if they do not have adobe flash player). An alternative is to have the students draw out a rough drawing of the completed cycle.

The teacher needs to review the BYOD/Internet acceptable use policies established by the teacher, school, district, or variation of the above.
