  1. Earths Changing Surfaces By Denise Bannard & Jaqueline Geary Fall 2009; 713.22 MST Inquiry Unit

  2. Table of Content • Lesson 1: Travel Through Geological Time • Lesson 2: Breaking It Down • Lesson 3: The Grand Canyon • Lesson 4: Shaky Ground • Lesson 5: Lava Mountain • Lesson 6: The Water Cycle

  3. MST STANDARDS • Standard 1: Students will use mathematical analysis, scientific inquiry, and engineering design, as appropriate, to pose questions, seek answers, and develop solutions • Standard 2: Students will access, generate, process, and transfer information using appropriate technologies. • Standard # 4 Students will understand and apply scientific concepts, principles and theories pertaining to the physical setting and living environment and recognize the historical development of ideas in science. • Standard 5: Students will apply technological knowledge and skills to design, construct, use, and evaluate products and systems to satisfy human and environmental needs.

  4. Geologic Time Scale

  5. Breaking It Down Scavenger Hunt Directions: Use the websites provided to look up the answers to the questions. Questions 1 & 2 go to Kidsgeo.com: http://www.kidsgeo.com/geology-for-kids/0059-introduction-to-erosion.php 1.What is Chemical Erosion? Chemical erosion brakes down the bonds that hold the rocks together. Chemical erosion is most common where there is water. 2.What is Mechanical Erosion? Mechanical erosion is when rocks are torn apart by physical force. An examples of this is when earths crust moves. Questions 3 & 4 are about Landslides: http://science.howstuffworks.com/landslide3.htm 3.What causes landslides? Landslides occur when gravity overcomes the force of friction. A common landslide is when rain mixes with soil on a down sloping hill. 4.Explain what a submarine landslide is? Where does this occur? A submarine landslide is a landslide under water. Submarine landslides trigger tidal waves.

  6. Questions 5 &6 are from National Geographic: http://science.nationalgeographic.com/science/earth/the-dynamic-earth/weathering-erosion-article.html 5. What plants benefit from erosion? Explain how? Linchens and Mosses can squeeze into cracks of rocks. As the plants grow they also cause the rocks crack to grow larger. 6.What forms glaciers? Explain. Glaciers are formed by snow and ice built up. The glaciers way down the rock and cause it to sink. Question 7 watch Pet Rock Theatre: http://www.youtube.com/watch?v=FCbgA9nY2bI 7. According to the video what causes rocks to smooth out? Sand, wind, and rain cause rocks to smooth after millions of years. Questions 8, 9, & 10 learn about different types of rocks: http://www.learner.org/interactives/rockcycle/types.html 8. What is a sedimentary rock? Explain using details. Sedimentary Rocks are formed from sand, shells, and pebble particles. They accumulate layers which causes them to harden into rocks. These rocks are usually soft enough to break easily. 9.What is a metamorphic rock? Explain using details Metamorphic rocks are formed under the surface of the earth from intense heat and pressure. These rocks are usually shiny on the surface. 10.What is a igneous rock? Explain using details. Igneous rocks are formed by magma. Those rocks are not shiny and some have small holes from gas bubbles.
