HOW EARTH HAS CHANGED OVER TIME AND WHY????

Let's take a step back in time to when earth first began. What was it like - hot? cold? hilly and green? rocky? What caused these changes?

  1. LESSON ONE: HOW EARTH HAS CHANGED

  2. Read the article below and make notes of the descriptions of what Earth was like over 4 billion years ago.
  3. Here is another great article. Have a read of it and take some more notes on the Earth's changes. Data that could be useful includes: dates; atmospheric changes; ground changes; temperature.
  4. BRAINSTORMING THINKING TIME

  5. Arrange all of your notes in chronological (date) order. Are there any other distinctive features that you may have forgotten to include? Take a look at the picture below to help you out.
  6. As a class lets compare notes and discuss what life would have been like living in these different times. Add to your notes any interesting facts that you may have missed.
  7. Explore the link below and its interactive features. Take more notes on the changing surface of Earth over time including causes for these changes e.g. volcanoes, shifts in the Earth's surface. What is predicted for Australia in the future?
  8. GROUP WORK

  9. IN GROUPS OF FOUR => CREATE: Design an infograph using Piktochart (the link is below) of the timeline of Earth changes. Be creative and colourful => search the internet to find pictures that demonstrate each stage, including what the surface of Earth was like during different periods of time and the atmosphere around it - was it hot, cold, icy, wet, dry? Was there any life and where did it exist? Leave room on your infograph to add some interesting facts that we will explore in our next lesson - "THE END OF THE DINOSAURS"
  10. LESSON TWO: THE END OF DINOSAURS

  12. For over four billion years Earth has been changing. The surface of the land has altered considerably caused by extreme weather and geographical events. We will continue on our journey of discovery and find out some more interesting facts about this.

  14. The Jurassic Era ended because an asteroid fragment, like the one above, collided with Earth. The impact was disastrous along with the many major geographical events that occurred following it. Some of these still happen now. Watch the documentary below and take notes on the names and distinctive features of these.

  16. BRAINSTORMING THINKING TIME

  17. We have now been introduced to tsunamis, earthquakes and volcanoes and understand more how these impact life, the surface of Earth and its atmosphere. In our next lesson we will explore this topic further, but to conclude today what can you recall about any of these events occurring during the different geological eras discussed in our last lesson? Discuss this in your group and make any necessary changes to your infograph.
  18. LESSON THREE: EARTHQUAKES, VOLCANOES AND TSUNAMIS
