summary of the main challenges for Christian educators in the field of Earth science, particularly regarding challenges between science and faith. While providing an overview of the challenges, also focus on one or two Earth science topics regarded as controversies by some Christians; as examples, some Christians disagree with others and with mainstream geologists about Earth age, radiometric dating, Creation Week, Noah’s Flood, the geologic column, and so on; also, Scripture contains some puzzles such as Joshua’s “long day.” Do not discuss biological evolution, which belongs in a biology course. Please be sure to acknowledge and deal with a range of viewpoints, or at least more than one, rather than presenting a one-sided perspective.
