Sixth graders simulate the creation of impact craters on Mars.Through the creation of model surfaces, the effects of an impacting object's mass, velocity and size are determined, and the features of the resulting crater are identified.

Students explore crater impacts. In this moon crater lesson students evaluate and interpret the physical characteristics of a crater. 

In this moon crater worksheet, students use images of craters taken from the Lunar Reconnaissance Orbiter to determine the size of the craters. This worksheet has 6 problems to solve.

Students explore the layers of the Earth and the dynamic changes that they cause on Earth's surface. Volcanoes and earthquakes become the focus of the lesson as the Oregon State quarter and its Crater Lake images are linked to the topic.

In this moon worksheet, students calculate information about the crater that was created by a massive impact. This worksheet has 3 problems to solve.
