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: 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.
