Space is a topic most learners find engaging. This article set out a short project investigating meteorite impacts, both practically and using simulations, and suggests resources that could be used. The formation of craters, such as those on the Moon caused by objects landing on its surface, is used to illustrate a study plan. The project is designed to improve learners' reasoning skills. The thinking behind the sequencing of the lessons (based on the principles of cognitive acceleration) is also discussed briefly.
