I-6 Assessment Flashcards
Look at the photo, and make a conclusion:
a) The larger the marble, the larger the crater.
b) The higher the drop height, the larger the crater.
a) The larger the marble, the larger the crater.
What is the likely size of the impact object that created a crater 100 km in diameter on the Moon? (Remember 20:1 ratio)
a) 100km
b) 50
c) 5
d) 0.2km
c) 5
Look at the photo, and make a conclusion:
He can’t be sure that the farther the marble falls, the bigger the crater is, because he used a different-size marble at each height. Maybe it was the size of the marble that caused bigger craters
He can’t be sure that the farther the marble falls, the bigger the crater is, because the drop heights are not high enough, and he needs to drop the marble even higher to get a accurate conclusion

What suggestions do you have to help the student improve the design of his experiment? (pick 2)
a) He wants to test the drop height, so he should not change the size of the marbles.
b) The size of the marbles are not big enough. He should get bigger marbles for better accuracy.
c) The student needs to make sure the drop heights are higher. That way the craters will better represent real craters.
d) He should redo the experiment using marbles that are all the same size to see if a higher drop height really creates bigger craters.
a) He wants to test the drop height, so he should not change the size of the marbles.
d) He should redo the experiment using marbles that are all the same size to see if a higher drop height really creates bigger craters.
After looking at the picture, be able to answer questions a-d
a. complex crater
b. mare
c. simple crater
d. C is a very small crater. If it had been there before the mare formed, it would
have been filled in. The lava formed the mare first, and later on c formed.
