Title: Discovering Earth's History
Description: This lesson introduces the basic principles that are used to interpret geologic time. It associates the relationships between the rock record and historical events that created the landforms on our planet. It explains how the rock record can be interpreted by geologists.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project, funded by the Malone Family Foundation.

Subject: Science (9 - 12)
Title: Radiation / Half-Life
Description: The students will evaluate their personal radiation dose. They will develop an understanding of the term radiation and how it relates to everyday life. The will simulate how radioactive material decays and apply the term half-life. Students will use a computer program to see that the half-life for different substances never changes. The students will evaluate nuclear power as a source of energy.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.

Subject: Science, Social Studies
Title: Splitting the Atom     
Description: The purpose of this lesson, from Science NetLinks, is to use the Internet to research the history of the splitting of the atom and to use that research to make a presentation on an aspect of that topic. The focus of the splitting-the-atom story should be on the discovery of nuclear fission and its impact on world affairs.

Subject: Health, Science
Title: Dangers of Radiation Exposure     
Description: The purpose of this lesson, from Science NetLinks, is to learn about sources of high-energy radiation and calculate student exposure to ionizing radiation over the past year. In the first part of the lesson, students calculate their yearly exposure rate to harmful high-energy radiation and cumulative effects over time. They then use the information to evaluate the various sources of radiation that are of greatest concern for them. In the second part of the lesson, students learn that spacecraft and other objects in space must be concerned with the same kinds of radiation to which humans are exposed.
