EDUCATION DESCRIPTION: Down to the Earth's Core
The hottest place on earth, even hotter than the sun's surface, lies 6400 kilometres away, in the inner sanctum of our planet. Take a journey from the footpath to the centre of earth in one epic unbroken step, smashing through solid rock to explore the hidden world beneath our feet. Deeper, beyond the reach of any mine, any drill, we find wonders beyond imagination: towering molten metal tornadoes, forests of solid iron crystals, until we reach the strangest, least understood place on the planet – the core. Withstand intense forces of heat and pressure along the way, to discover the home of the raw materials that shape and power our civilisation.

TEACHER BACKGROUND INFORMATION
Human ingenuity has allowed us to uncover many secrets in our universe, from dark matter to the moon and even outer space. And yet we still have no idea what lies in the very heart of our own home planet – earth's core. From the earth's surface, this documentary examines the forces that affect our lives including plate tectonics, the formation of gold, diamonds and oil.

Through computer technology, we see how earthquakes are born from waves of energy blasting through hundreds of kilometres of solid rock, a grim reminder of the violent forces hidden below our feet.

Ironically, our planet is both destroyer and creator. The same intense tectonic forces that cause volcanoes and earthquakes also help to form two of our most prized possessions, gold and diamonds.
As we journey deeper beneath the surface, more facts are revealed: how colonies of humble bacteria rendered the earth livable, how the iron that keeps civilization standing was formed, and how a thick layer of dead plankton on the ocean floor was transformed into the oil upon which we are now so dependent.

Four and a half billion years since our planet first evolved, we owe our existence to the heat at its core. Everything that makes our world beautiful – and volatile – is derived from this almighty, ancient energy source.


CURRICULUM POINTERS
 

Upper Primary Curriculum
The science curriculum provides opportunities for students to develop understandings about science and its processes, the scope of its contributions to our culture and society, and its applications in our daily lives.
Australian Science K-10 Curriculum 2010: Rationale

Junior Secondary Curriculum
Science provides an empirical way of answering interesting questions about the biological, physical and technological world. The knowledge it produces has proved to be a reliable basis for action in our personal, social and economic lives.

CURRICULUM OUTCOMES
 

Upper Primary
In undertaking these tasks, students of Science will:
•    Develop an interest in science and a curiosity and willingness to explore, ask questions and speculate about the changing world in which they live
•    Develop an ability to communicate their scientific understandings and findings to a range of audiences, to justify their own ideas on the basis of evidence, and to evaluate and debate scientific arguments and claims whilst respecting alternative viewpoints and beliefs.
Australian Science K-10 Curriculum 2010: Aims

Junior Secondary
In undertaking these tasks, students of Science will:
•    Develop an ability to communicate their scientific understandings and findings to a range of audiences, to justify their own ideas on the basis of evidence, and to evaluate and debate scientific arguments and claims whilst respecting alternative viewpoints and beliefs.
•    Develop a solid foundation in science knowledge and understanding of the  …  physical and earth and space sciences, including being able to select and integrate science understanding in order to explain and predict phenomena, to apply that understanding to new situations and events, and to appreciate the dynamic nature of science knowledge.

STUDENT LEARNING TASKS
 

Upper Primary
 

Task 1
Draw a cross-section of the earth showing the layers from the core to the crust. Use labels and colours to show the different layers.  
 

Task 2
Write a couple of sentences to explain how coal is made.
 

Task 3
Draw a timeline that beings 4.5 billion years ago to show some of the major stages in the evolution of our planet. Mark the following:
•    Rocks circle the infant sun
•    Stromatolites convert sunlight into food, releasing oxygen, making gas breathable
•    The mineral gold forms deep beneath the earth's surface
•    An asteroid hits Earth, wiping out 75% of life, including dinosaurs
•    Diamonds blast from the mantle into the earth's crust

Task 4
Write a couple of paragraphs to describe the earth's magnetic shield and explain how it protects us from deadly solar wind.

Task 5
Draw a diagram that shows how oil was formed from prehistoric plankton.


Senior Secondary
 

Task 1
Draw a cross-section of the earth showing the layers from the core to the crust. Label the different layers and mark each one's thickness.  For each layer, write a sentence to describe its composition.

Task 2
Write definitions for each of the following:
•    Asteroids
•    Fossil fuel
•    Stromatolites

Task 3
In about 50 words for each, explain how oil and coal are formed.

Task 4
Draw a diagram to show how diamonds are formed in the earth's mantle and how they travel from there to the crust.

Task 5
Write 200 words to explain how planet Earth evolved including how the core is integral to the earth’s structure.
