Title Quake City Activity 1 Apartment A teaching sequence from the Hollywood unit
Objectives <ul><li>To model the structure of the Earth to investigate where earthquakes may occur. </li></ul><ul><li>Explain what causes earthquakes and identify where they can happen. </li></ul>OBJECTIVES
Sequence Engage (optional) Great to see you cousin! Welcome to Hollywood. You are going to love spending your gap year here... Hollywood, San Fran, hanging out with all the stars!
Engage (narrative) Take a look at the details. It has TWO bedrooms so you could lodge with me! What do you think? SS1 I’ve found this apartment – great location, and cheap too.
Elicit (narrative) All those safety features really worry me. What do YOU think? Why does it need earthquake protection? I do NOT want to invest my money in a property that might collapse. discuss
Elicit (info) The books say that the Earth is formed from different layers but that doesn’t tell me anything. I can see no difference between here in Hollywood and back home in the UK. crust inner core outer core mantle
Elicit (task) I need you to find out more. Try the exhibition at the Science Centre... SS2–6
Explore (narrative) Welcome to our latest interactive exhibition .
Explain (info) The Earth’s crust and upper part of the mantle are thought to consist of large pieces called tectonic plates.
Explain (info) Scientists believe that there are convection currents within the mantle. The mantle is mostly solid but is able to move slowly.
Explain (info) The plates move relative to each other at a few cm each year. San Andreas Fault, California It is thought that the convection currents cause this.
Explain (info) The edges of the plates are called plate boundaries . At some plate boundaries the plates try to slide past each other. The location of earthquakes in the last 30 years.
Explain (info) The plates are moving against each other all the time but they cannot slide because of friction. The energy gets stored . An earthquake happens when this movement energy finally overcomes the friction and all the stored energy is released at once in a sudden movement. The edges of the plates are rough, like sandpaper.
Evaluate (task) What do you think – SS7 should I go ahead with the apartment?
