This interactive tutorial provides students with an overview of Earths history and its relation to geologic time. Topics include the age of the Earth, the use of timelines, and the concepts of relative and actual age. Once these topics have been covered, their applications to rocks and fossils are explained through the concepts of superposition (oldest rocks on the bottom), the use of fossils to determine relative age, and the use of radiometric dating to determine absolute age. There is also an interactive geologic time scale where students can find descriptions of what the Earth was like by clicking on the various eons, eras, or periods.

| Description | The Digital Library for Earth System Education (DLESE) mission is to improve the quality, quantity, and efficiency of teaching and learning about the Earth System, by developing, managing, and providing access to high-quality educational resources and supporting services through a community-based, distributed digital library. Intended users include students, educators and citizens of all ages, in both formal and informal learning environments. The collection favors resources that convey linkages and connections; the general with the specific, theory with evidence, global with local, and that demonstrate the application of science to solving real world problems. This includes providing access to Earth data sets and imagery, and the tools and interfaces that enable their effective use. DLESE resources are community-contributed, by individuals, organizations, and formal collection efforts. |

| Description | The Middle School Portal 2: Math and Science Pathways (MSP2) supports middle grades educators with high-quality, standards-based resources and promotes collaboration and knowledge-sharing among its users. Educators use MSP2 to increase content knowledge in science, mathematics, and appropriate pedagogy for youth ages 10 to 15. MSP2 employs social networking and digital tools to foster dynamic experiences that promote creation, modification, and sharing of resources, facilitate professional development, and support the integration of technology into practice. MSP2 is a project of the Ohio State University College of Education and Human Ecology, National Middle School Association, and Education Development Center, Inc., and is funded by the National Science Foundation. The partners integrate resources, tools, and services across projects, and support multiple methods of resource discovery to meet the needs of this audience. |
