Earthquake Lesson Plan Topic: Earth’s Changing Surface NSES: SCS D 1.1, 3.1 SOL: 5.7d Daily Question: How do tectonic plates affect the Earth’s surface? Date: November 11, 2008 Grade level: 5th Subject: Earthquakes Procedures for Learning Experience Guiding Questions Materials Needed Engagement: Ask the children if any of them have ever been in an earthquake. If one of them has, ask them to describe what it felt like. Show the earthquake video to introduce what it is like to be in an earthquake and the damage it can cause. Now ask them to hold their hands up in front of them. Put your hands together with the palms facing each other. Push really hard. Your hands are acting like two plates pushing together. Keep pushing your hands together, but now try to move one hand up and the other down. Did you feel it when your hands jumped to their new place? Exploration: First, remind the students of their discussion of tectonic plates by asking them to recall the three different types of faults: convergent, divergent, and transform. Have them write their own definition of the faults in their learning log and then ask some children to share their Have you ever been in an earthquake? Earthquake video clip from YouTube How do you think an earthquake would feel? Evaluation (Assessment) Participation in discussion and in brief demonstration Approximate Time Needed 5-10 minutes Written definitions of the three types of faults 25 minutes Did you feel it when your hands jumped to a new position? What are the three types of faults? Two wooden blocks per student What fault did we represent with our clay and wooden blocks? Section of clay per student Wax paper Written observations definitions with the class. Now let's see what happens when this happens on in the Earth. Give each student two wooden blocks, a section of clay, and a piece of newspaper or wax paper to work on. Have the students put the two blocks together with the long ends touching. Now have them press the clay down on the paper until it is a sheet large enough to fit over the two blocks of wood. Put the clay on the two blocks and push down until the clay is stuck to the wood. Use your pencil to draw a road across where our blocks meet (the fault). Have the students use their blocks to make a convergent, divergent, and transform fault. Write down any observations you have about the clay surface when each of these faults occur. Have the class share their observations with the other students at their table (groups of 3-4). Collect all supplies from this activity. Divide the class into six groups (3-4 students per group). Assign each group a different activity to test. In one group give them a slinky and ask one person hold one end while another person holds the other end of the slinky while compressing a portion. Release the compressed end and write any observations. What happens when the compressed portion is released? How does that fault behave? Pencil What observations can you make about the slinky and the rope? How do they act the same? Different? Golf ball (at least 2) How did the golf ball and ping pong ball act when dropped in water and when dropped on the table? Did they act the same or different? How? Slinky Ping Pong Ball (at least 2) Length of Rope Container of water (2) – a pan or storage container Paper Towels Goggles about the fault they created with the blocks and clay Written observations of the primary and secondary wave activity In group two give them a rope and have someone hold either end. Swing the rope back and forth and write observations. The next two groups will either be given a golf ball or a ping pong ball. Drop the ball into a container of water and write observations. Did the ball you used sink or float? Finally give the next two groups either a golf ball or a ping pong ball. Drop the ball on a desk and observe how much and how frequently it bounces. What observations can you make? Have the students come back together as a class and each group share their observations with the class. Explanation: When the energy is released between two plates the plates jump to their new position, like your hands did, and cause an earthquake. When the earthquake occurs there are two types of waves created: primary and secondary. Explain primary and secondary waves in terms of the slinky (primary) and rope (secondary) as well as golf ball (primary) and ping pong ball (secondary). Introduce and define the concepts of epicenter, focus, and seismograph (how the epicenter is determined using readings from three different seismographs.) What is a primary wave? How does it act? What is a secondary wave? How is it different from a primary wave? What is an epicenter, focus, and seismograph? What does a seismograph do and how is it helpful? See Exploration Participation in discussion Have students write the definition of the different types of faults, waves, epicenter, focus, and seismograph in their own words in their learning log 10 minutes Extension: Have the students make a seismograph and test it. See the attached sheet for how to set it up. Explain the instructions to the students and have them get in three groups and each group make a seismograph. Use a very rough idea of triangulation to find the epicenter of an “earthquake” with the use of the seismographs. How does the epicenter change depending on the size of the reading at each seismograph? How does the epicenter change when the size of the reading changes? Where is the epicenter in relation to the seismograph with the strongest reading? Books to stack Creation of the seismograph 30 minutes Ruler Understanding of Cup how the seismograph String works and how to approximate the Gravel epicenter based on three Pen/Pencil/Marker seismographs Calculator Tape Notes: This lesson will be following a discussion of plate tectonics which will be introducing the idea of different faults. Students should already have an understanding of convergent, divergent, and transform faults before beginning this lesson. Following this lesson the students will enter a lesson about volcanoes and their relation to plate tectonics as well. In terms of safety notes, it may be beneficial to have students wear goggles when completing the group activities with the slinky, rope, golf ball, and ping pong ball since some of those items could be harmful if the proper procedures are not followed.
