  1. 1. BUILD A HOUSE THAT WILL SURVIVE AN Earthquake In California A 6th grade science
  2. 2. Relevant Science Standards for 6th grade 1.E Students know major geologic events, such as earthquakes, volcanic eruptions, and mountain building, result from plate motions. 1.F Students know how to explain major features of California geology (including mountains, faults, and volcanoes) in terms of plate tectonics. 1.G Students know how to determine the epicenter of an earthquake and know that the effects of an earthquake on any region vary, depending on the size of the earthquake, the distance of the region from the epicenter, the local geology, and the type of construction in the region.
  3. 3. INTRODUCTION You and other experts have been asked to consult with a millionaire that wants to build a mansion somewhere in California. He has asked that it be especially safe from the dangers of earthquake damage. In your group there are people from the U. S. Geological Survey and some building contractors. You will do research for and advise the client on the safest places to build a mansion and advise its construction to best withstand any possible earthquake damage. To achieve this you will identify earthquake prone areas and ways to make structures safer in earthquakes.
  4. 4. PROCESS & RESOURCES: The first step is to find a location to build the mansion. You will research websites that provide information about earthquake activity in different parts of California. You will identify and suggest three different places that are historically not as likely as other places, to experience a serious earthquake. These locations will be suggested places to build the clients house. The location should be a convenient distance from a city or town so that the client can have access to things that they need. For each of the three locations, name the nearest fault line and give the approximate distance from that fault.
  5. 5. Utilize the following sites for information: • Loads of California fault information http://sanandreasfault.org/ • Earthquake potential map of California – It shows where earthquakes are more likely to happen http://www.classbrain.com/artstate/publish/ca_eart hquake_map.shtml Where is it safer to build in California? http://www.earthquakecountry.info/roots/contents .html
  6. 6. Next Job: Research some building techniques that will help protect the structure from shaking and help it withstand possible earthquake damage. Make a list of five different earthquake modifications to a home that will make it more likely to survive an earthquake. Explain what each does to help prevent damage to the home. Find and provide at least three pictures of equipment or types of modifications that can be used to make structures withstand earthquakes. Identify four different potential hazards in a typical home and how to fix them to be more secure.
  7. 7. The following sites have great information on building in earthquake country: “Putting Down Roots in Earthquake Country” How to prepare for an earthquake http://www.cnico.com/pdf/socal-quake.pdf Techniques for reinforcing homes to withstand earthquakes http://www.reidsteel.com/information/earthquake_resistant _building.htm More on next page….
  8. 8. Building Techniques Continued…. Base-isolated construction techniques for single homes http://www.hrd-s.com/pro_base.html Earthquake resistant construction techniques http://www.ehow.com/info_8680235_earthquake-resistant- construction-techniques.html How to make house earthquake proof http://www.commonfloor.com/guide/make-your-home- earthquake-proof-421.html
  9. 9. 10 points5 points 20 pointsCriteria List 3 locations to build a house in California that have a very low danger of experiencing an earthquake. 3 fault locations are named and the approximate distance from the building location is given Make a list of 5 different types of earthquake modifications to a home. Provide at least 3 pictures of equipment or modifications that can be used. Identify four different potential hazards in a home that can be fixed to make the home more secure Only one location is given with the nearest fault and approximate distance away. Two locations for building sites are given and at least the nearest fault and approximate distance to it are given. Three locations for building sites are given and the three nearest fault lines are given. The approximate distance to the particular fault is given. Total 5 modifications are listed, along with what they do to help, 3 pictures of equipment or modifications are provided. 3 – 4 modifications are listed, along with what they do to help. At least 2 pictures of equipment or modifications are provided. Only 1-2 modifications are listed, along with what they do to help. At least 1 picture of equipment or modifications is provided. Four different potential hazards in the home are identified and how to fix is explained. Only 2-3 potential hazards in the home are identified and how to fix is explained. Only 1 potential hazard in the home is identified and how to fix it is explained. Grading Rubric - Earthquakes
  10. 10. Conclusion After completing this WebQuest you will be familiar with tectonic plate boundaries, fault lines and earthquake zones in California. You will be familiar with how earthquakes cause damage to buildings and homes, and how the risk of damage from earthquakes may be diminished. You and your classmates have learned how to make modifications to an ordinary home to make it safer during an earthquake, and become familiar with and understand how different building techniques can make a building more likely to withstand the shaking of an earthquake.
  11. 11. Extra Activities Now that you know how to make a residential home more earthquake resistant, how do you think that it can be done to a skyscraper! Next…
