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.
Subject: Science (9 - 12), or Technology Education (9 - 12)
Title: Living in a "Submicro" World
Description: This is a technology-based lesson plan designed for high school Chemistry students as an introduction to the study of the fundamental nature and structure of the atom. Students will create a publication using Desktop Publishing software to support the content of this unit.

Title: Radioactive Decay: A Sweet Simulation of Half-Life
Add Bookmark
Description: In this Science NetLinks lesson, the second lesson in a three-part series about isotopes, radioactive decay, and the nucleus, students are asked to simulate radioactive decay by pouring small candies and counting which candies fall with their manufacturer's mark down or up. The exercise they go through of predicting and successively counting the number of remaining '' mark-side up'' candies should help them understand that rates of decay of unstable nuclei can be measured, that the exact time that a certain nucleus will decay cannot be predicted, and that it takes a very large number of nuclei to find the rate of decay.

Title: Splitting the Atom
Add Bookmark
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.

Title: Zeolites
Add Bookmark
Description: In this Science Update, from Science NetLinks, you'll hear about a way to trap and seal up toxic waste using zeolites, a family of cage-like molecules. Science Updates are audio interviews with scientists and are accompanied by a set of questions as well as links to related Science NetLinks lessons and other related resources.

Title: Submarines: Underway on Nuclear Power
Add Bookmark
Description: In this lesson, from Xpeditions, students consider the role of nuclear submarines during the Cold War. They explore the uses of nuclear submarines, the dangers faced by their crews, and the effect of the Cold War build-up. They look at incidents involving submarines both during and after the Cold War, including the K-19 disaster. Finally, students assemble their findings into a classroom presentation.

Title: Science NetLinks
Add Bookmark
Description: The American Association for the Advancement of Science's Science NetLinks strives to be a comprehensive ''homepage'' for K-12 science educators. At the heart of Science NetLinks are standards-based lesson plans that incorporate reviewed Internet resources, and can be selected according to specific benchmarks and grade ranges. Each lesson is tied to at least one learning goal and uses research-based instructional strategies that support student learning. The lessons are written for the teacher, but include student-ready materials such as student sheets (student reproducibles) or E-Sheets (online worksheets that enable students to engage directly in Internet activities). Science NetLinks is a member of the MarcoPolo consortium.

Title: Feather Analysis
Add Bookmark
Description: In this Science Update, from Science NetLinks, you'll hear about a technique for tracking the migration of songbirds that involves analyzing their feathers. Science Updates are audio interviews with scientists and are accompanied by a set of questions as well as links to related Science NetLinks lessons and other related resources.

Title: Frosty the Snowman Meets His Demise: An Analogy to Carbon Dating
Add Bookmark
Description: The purpose of this Science NetLinks lesson is to develop the idea that carbon dating is based on gathering evidence in the present and extrapolating it to the past. Students use a simple graph to extrapolate data to its starting point.

Title: Isotopes of Pennies
Add Bookmark
Description: This Science NetLinks lesson, the first in a three-lesson series about isotopes, radioactive decay, and the nucleus, helps students build their understanding of the properties of matter. Specifically, it helps them understand that average atomic mass is not a simple average, but is weighted according to percent abundance. Before working on this lesson, students should be familiar with the periodic table and should have had some basic instruction in the following concepts: isotopes, mass number, and atomic number.
