Measuring impact craters on the Earth

This worksheet will guide you through how to download Google Earth, how to navigate to each impact crater, how to measure the diameter of each crater and to put the sizes of these craters into perspective. You will then be asked to calculate the kinetic energies involved in some of the impacts which have created these craters.
