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.

What will I need for this activity?

• Google Earth - download from: http://earth.google.com/

Use Google Mars to observe some real impact craters on the Martian surface.

We suggest you try the activity; 'Measuring impact craters on the Earth' first as this activity compares craters and surface features on the two planets.

The Down2Earth Meteorite Loan Box is the focal point for this activity. Students examine and draw the meteorites, with and without magnification, consider their density and compare them with Earth rocks.

This activity worksheet guides students to reproduce some of the prominent impact craters on Earth. Using the Impact Calculator to model the conditions that created these craters, students can learn about the various factors contributing to the destructive potential of meteorite impacts and how our understanding of theory helps to form a picture of these catastrophic events in Earth's violent history.

Back Down 2 Earth (BD2E) is an expansion of the existing Down 2 Earth (D2E) education project which teaches school students aged 11-19 about the geological side to astronomy. In this 46-page booklet you will learn about the wonders of comets and asteroids and the possible destruction that these bodies can cause on planets such as our own.

View this as a web-page (some material omitted).

There are 2 parts to this activity which should both be carried out prior to the Deep Impact mission. The aim of this activity is to learn about the specific features of craters.

A simple literacy task for KS2 or KS3 students to help familiarise them with terms relating to comets.

Meteorite impacts are devastating events but it is not only the impact itself which causes destruction but the after effects of these phenomena which can be just as catastrophic. From stratigraphic records and accounts of recent impact events we can build up a picture of various resulting disasters encountered when these space rocks collide with the Earth.

This document provides a concise background to meteorites including what they are and where they come from.
