1) The Structure of the Earth
Task 2) Learning the Structure of the Earth
1) Head to the website "Moorland School" and read carefully the entire page. 2) Draw a diagram of the interior of the Earth's crust IN PENCIL with the labels - inner core, outer core, mantle and crust. 3) Make notes about each layer which state: a) the depth b) the average temperature c) the state (solid, liquid, gas) of the layer d) anything special that layer 4) Then click on "Earth Structure Test" and see if you can complete it 5) Finally go back to the diagram in step 3 and, using the internet, add the asthenosphere and lithosphere. When you are sure that you have a well designed diagram, add colour! |
2) The Earth's Tectonic Plates and Continental Drift
The Earth below our feet appear to be fairly solid but in fact it is changing all the time...
The Earth below our feet appear to be fairly solid but in fact it is changing all the time...
Task 1) Watch Video: Pushing and Shoving
(20 mins) Learn about what the surface of Earth really looks like, how it moves and what happens!!!
|
Task 2) Research Plate Tectonics
Now it is time to conduct your own research, learn more and understand a small part of our Earth's history!!! Read SF3 Unit 9.1) Plate Tectonics pg 281 - 284 then answer the questions on the WORKSHEET to see how well you comprehend the information. Important! Pay close attention to question 4 - many students find this one difficult to understand. |
Task 3) Create your own World Map showing the Tectonic Plates
Task 4) Experiment: What is moving the plates????
1) Set up the experiment exactly as shown by placing a 500 mL beaker on the tripod, then hold the straw so it firmly touches the bottom of the beaker, then add water so the beaker is almost full and finally add the potassium permanganate crystal to the bottom of the 500 mL beaker using a straw. REMEMBER: DO NOT TOUCH THE CRYSTAL WITH YOUR HANDS 2) Observe and sketch the movement of the colour through the water 3) Explain why this occurs. Use the MOTO below: Heat an object ----- particles vibrate more and spread out ----- decrease in density ----- move upwards
Cool an object ------ particles vibrate less and come closer together ------ increase in density ----- move down wards |
