EcoLogic unit of work: 'Changing Times, Changing Lives' slideshow

7,379 views

Published on

This pre-visit slideshow forms part of a Unit of Work : ‘Shaping the Future’ designed for Stages 4 & 5 Science and Geography.

It has been developed as a pre-visit activity to help teachers facilitate class discussion on how humans meet the challenges of a changing world.

It thus provides students with greater context for their learning during their visit to the EcoLogic exhibition.

The slideshow has support notes for teachers to refer to as they go through the various slides with their class

  • Australian population is almost 50x greater now.
    World population is almost 5x greater.
    Transportation has become much quicker and easier, with a range of public and private transport options.
    International and domestic air travel is commonplace and quick.
    Space travel is no longer a major news item and humans live in space for long periods of time.
  • Before steam there was:
    water power (commonly used in mills)
    horse power
    people power
  • Coal was used to create steam in big boilers.
    We still use coal to produce most of Australia’s power.
    Coal is a fossil fuel, so there is a limited amount available. When this has all been mined, we need a new energy source.
    In addition to a limited supply, burning coal releases carbon dioxide. This greenhouse gas may be causing global warming.
  • The steam engine allowed firefighters to pump large amounts of water and quickly extinguish a fire. It was much more effective than a hand pump or buckets. This fire engine would stop fires from spreading, saving lives and property.
  • Steam wasn’t just for work – it allowed new types of recreation, too.
  • The introduction of railways allowed the movement of large numbers of people and large loads of goods. Suddenly, it was possible for producers to reach new markets and for people in distant communities to get goods from urban centres. People could travel further, faster and with greater comfort than ever before.
  • Today’s technology is lighter in weight and smaller in size.
    Heavy steel and wood objects have been replaced with lightweight alloys and plastics.
    We use electricity for most household uses and petrol for private transportation.
    We use steam turbines to produce electricity. This means that we still burn coal to produce steam. The major difference is that this process occurs in power stations rather than in mobile machines.

    2. 2. 1850 1. Australian population = 405,356 2. World population = 1.26 billion 3. Average lifespan: man = 38, woman = 40 4. Loco No 1 (inset) pulled the first trains in NSW Steam was produced by burning coal. 5. Most people travelled by horse or on foot. 6. Powered flight was for the birds.
    3. 3. 1900 1. Australian population = 3.8 million 2. World population = 1.65 billion 3. Average lifespan: man = 51, woman = 54 4. Most Sydneysiders rode electric trams in the city. 5. Motoring was in its infancy and petrol was purchased in tins from chemists and grocers. 6. In 1903 the Wright Brothers made the first powered flight.
    4. 4. 1950 1. Australian population = 8.3 million 2. World population = 2.52 billion 3. Average lifespan: man = 66, woman = 71 4. Qantas offers regular passenger service on the Kangaroo Route to London. It takes 4 days! 5. In 1951 Holden introduces the coupe utility – Australia’s first ute. 6. Trams close in 1961 as most Sydney residents travel by train, car or bus.
    5. 5. 2000 1. Australian population = 19 million 2. World population = 6.06 billion 3. Average lifespan: man = 77, woman = 83 4. Electric trams are back in Sydney CBD. 5. Toyota Prius hybrid car available worldwide in 2001. 6. Qantas flies nonstop from Sydney to London in 23 hours. 7. Humans live in the International Space Station.
    6. 6. v v What has changed in the past 200 years? Review the last 4 slides and talk about what has happened to: • Australian and world population. • Average lifespan. • Transportation within Sydney and around the world. What do you think will happen by 2050?
    7. 7. Changing Technology The Steam Revolution Life before the steam revolution What power sources were available before steam power?
    8. 8. What fuel was burned to create steam? Do we still use this fuel? What is the problem with continued use of this fuel?
    9. 9. Steam was a new technology that changed the world. How did the steam engine in this horse-drawn fire engine affect people’s lives?
    10. 10. A steam engine was used to power this merry-go-round. How did people use this technology?
    11. 11. How did steam engines like Locomotive Number 1 impact people’s lives?
    12. 12. After the revolution Steam power required big, heavy, metal engines. How is today’s technology different? What materials are used to make new technologies? What power sources do we use? Steam has a very important use now – do you know what it is?
