In woodcuts such as Holbein illustrates Lutheran ideology as well as Luther’s attacks on Rome, while simultaneously working with traditional humanists.
The study of fossils and the exploration of what they tell scientists about past climates and environments on Earth can be an interesting study for students of all ages.
Scientific measurements such as radiometric dating use the natural radioactivity of certain elements found in rocks to help determine their age.
Scientists also use direct evidence from observations of the rock layers themselves to help determine the relative age of rock layers.
Once students begin to grasp "relative" dating, they can extend their knowledge of geologic time by exploring radiometric dating and developing a timeline of Earth's history.
These major concepts are part of the Denver Earth Science Project's "Paleontology and Dinosaurs" module written for students in grades 7-10.
