Craters Research Project
Split into teams.  Each team takes a question:

-Where are the main craters in the world?  How big (diameter and depth) are they?

-Where are the major craters in the solar system?

-Why are there regions on the moon with few or no craters while other parts have millions of craters?

-What is some of the evidence that leads us to believe a giant cometary or asteroid impact resulted in the extinction of the dinosaurs?

-What are meteors made of?

-What is the difference between these terms: asteroid, comet, meteor, meteorite, and chondrites.

-If a 100-meter diameter asteroid has an energy of 1 Hiroshima bomb, use simple proportionalities (kinetic energy and mass-volume) to show than a 1000-meter (1 km) diameter asteroid will have an energy roughly equal to ______ Hiroshima bombs. Show your work.

-Argue the case for and against the funding for Astronomers to hunt for Apollo asteroids.

-What causes meteor showers?  Do any of these meteorites ever cause damage?

-What are the Kuiper Belt and the Oort Cloud?  Why might these be important to know about in geology?

-Where are most of the asteroids in the solar system?  Where did they come from?

-Why do comets have two different tails, a dust tail and a gas tail?

-Normally, metallic (iron) meteorites are the most commonly found, because stony meteorites are easily mistaken for ordinary rocks. There is a place on Earth, however, where it is easy to find a representative sample of meteorites. Where is it, and why is a sample collected there representative?

-How do astronomers use meteorites and craters to find the age of our solar system?

-What is the anatomy of a crater? Draw a crater or make a model of one and label its main features.

-Design an lab/activity/experiment that would demonstrate the differences in the impact craters of meteorites of various sizes and velocities.  Write it up as though the entire class will do it.
