Subject: Mathematics (9 - 12), or Science (9 - 12)
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.
