The resources in this section are thus either a subdivision of a larger earth science resource or the larger resource within which geologic time is addressed.

Parts of some of these resources are appropriate for students, while others are more appropriate for teachers or more advanced learners only.

The Science Educator’s Guide to Selecting High-Quality Instructional Materials This guide presents a method for judging the quality of K-12 teaching materials, both in print and online.

It is based on AAAS Project 2061’s curriculum-materials analysis procedure which was developed over several years with funding from the National Science Foundation and in consultation with K–12 teachers, materials developers, scientists, teacher educators, and cognitive researchers nationwide.

Relative time can be thought of as the subdivisions of rock found in the earth’s stratigraphy and absolute time as the measurements taken of rock types to determine the actual time that has expired.

With its step-by-step procedure for taking a critical look at instructional materials, the guide can help science educators take a more informed approach to a number of essential tasks.

Geologic Time is captured in at least two different areas. The other is under the Physical Setting--Changes in the Earth's Surface which includes rates of change.

An image of the middle grades (6-8) only part of the Changes in the Earth's Surface map appears below.

The site contains a multicolor time scale and references for more information.

The text is appropriate as teacher background knowledge; the graphic is appropriate for students assuming some discussion and explanation accompany it.
