Title: Symmetry: Theory, Reality and Art!
Description: Students will explore symmetry as defined in geometry, as seen in their community and through the art of Escher-Escher Art Website. Technology and art are incorporated in this lesson. The incorporation of art is an important element in developing the ‘whole child’ if a school system has been forced to eliminate a formal arts program. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.

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.

Title: Let’s Tessellate
Description: This lesson is a hands-on, technology-based project that will take place in the classroom and computer lab. Students will discover which regular polygons tessellate the plane by constructing polygonal tessellations. Students will also use a spreadsheet to calculate the area and perimeter of the polygons.

Title: Golden Ratios of the Body, Architecture, and Nature
Description: Students will study the golden ratio as it relates to human body measurements, architecture, and nature. Students will use a desktop publishing program to create a poster. The poster will have digital photos of themselves, architecture samples, or nature examples. Students will also include a spreadsheet with the lengths, widths, and length/width ratios of the samples included in the photos.

Title: Transformations and Frieze Patterns
Description: In two lessons, this unit will introduce students to the world of symmetry and rotation in figures and patterns. Students learn to recognize and classify symmetry in decorative figures and frieze patterns, and will also get the chance to create and classify their own figures and patterns using JavaSketchpad applets.

Title: Art Algorithms
Description: In this Science Update, from Science NetLinks, you'll hear about new methods of art conservation. Art conservation is traditionally a painstaking and time-consuming business. But the process of fixing up a damaged da Vinci or a scarred Seurat may become a lot easier, thanks to the work of mathematicians. 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.
