1.7 crater formation

  1. 1. 1.7 Craters: what makes them? January 28, 2015 There were two theories for this crater formation: either a volcano exploded OR an asteroid smashed into Earth. What evidence would you look for to prove or disprove either theory?
  2. 2. Aims • Revise KS3 ideas about the solar system • Review data and explanations for craters
  3. 3. Investigating crater impacts • You are going to investigate the effect on crater size with the height (and therefore the speed) of impact • INDEPENDENT VARIABLE (x): • DEPENDENT VARIABLE (y): Height / m Crater depth / m Crater radius / m
  4. 4. For people who want an A* • Height is really not the interesting factor but it’s the speed at which hits. • You may have come across the following equations: • You could then plot energy against crater size or even you are super smart the velocity against height. • You decide! velocityv heighth strengthfieldnalgravitatiog massm : 2 1 2 = = = = = = where mghE mvE p k
  5. 5. To do: • Decide what factor you will investigate (radius or depth) • Write a statement of your hypothesis (If I increase the height I drop the ball from, then…) • Decide what heights you will drop the asteroid from. • Drop the ball and record your data in a table • Draw a graph of the data • Write a statement of your conclusion (I found out that the higher the ball…) • Evaluate your experiement (To improve my results I would…)
