STUDENT INSTRUCTION AND ANSWER
Activity 1: Exploration-How
many craters are on the Moon?
Below is a 2.7 square kilometer (2.7 km2) image of the Apollo 14 landing site on the Moon. You can divide the Moon's surface up into 14,000,000 such patches. Write a step-by-step plan for estimating the number of craters on the Moon that are larger than a football field. After you have shown your plan to your teacher, carry out your plan and compare your results to the class average.
