  1. https://www.youtube.com/watch?v=W4N_FpEcxk4

  2. This meteor broke up in Earth’s atmosphere. What would have happened if the meteor had exploded on impact with Earth instead?

  3. ‘Meteor Crater’, Arizona, USA.

  4. The crater is: • 1,200 m across ‘Meteor Crater’, Arizona, USA.

  5. The crater is: • 1,200 m across • 170 m deep ‘Meteor Crater’, Arizona, USA.

  6. The crater is: • 1,200 m across • 170 m deep • is surrounded by a rim 45 m higher than the surrounding plains ‘Meteor Crater’, Arizona, USA.

  7. The crater is: • 1,200 m across • 170 m deep • is surrounded by a rim 45 m higher than the surrounding plains • has a 240 m wide pile of rubble (peak) in its centre ‘Meteor Crater’, Arizona, USA.

  8. But Meteor Crater in Arizona is tiny compared with other impact craters in the Solar System. Meteor Crater (1.2 km wide)

  9. Where could we find larger impact craters in the Solar System?

  10. Tycho Crater (85 km wide)

  11. Ejecta Rays Tycho Crater Ejecta Floor Wall Rim Central Peak

  12. Why do some meteors make larger craters than others? Discuss this is your groups.

  13. Today, we are going to investigate how to create our own meteor impacts.

  14. What questions about the formation of craters would you like to investigate? Discuss this in your science groups.

  15. Craters Investigations. • Look at the materials provided • How could you investigate your question? • Discuss this with your group. • On your planning sheet, record: - the materials you will need - the steps you will take - what you will change - what you will keep the same - what you will record - how you could present your results - SAFETY ISSUES!!!!
