Title: Graphing at all levels: It’s a beautiful thing!
Description: This lesson addresses the societal issue of the arts being eliminated in many public schools be employing graphs (at any level) as an artistic media. Review of all types of graphs is included through various interactive websites.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: Mathematics (9 - 12), or Science (9 - 12)
Title: Ellipse
Description: This lesson is designed for an Algebra II through Pre-Calculus classes and introduces the conic section- an ellipse. In this lesson students explore an ellipse, the set of points in a plane such that the sum of the distances from each point to two fixed points is constant. The students will investigate the construction of an ellipse and be able to recognize its major axis, semi-major axis and focal points and to be able to compute its eccentricity. 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: Mathematics (9 - 12), or Technology Education (9 - 12)
Title: Going the Distance for Circles
Description: This lesson is designed for an Advanced Mathematics class and introduces the first conic section - a circle. The definition and important information related to circles is presented in a multimedia presentation. Students are then required to document what they have learned in a brochure.

Subject: Mathematics,Science
Title: Analyze the Data
Description: In this lesson, one of a multi-part unit from Illuminations, students use rational functions to investigate the feeding behavior of Northwestern Crows. Biologists have observed that northwestern crows consistently drop a type of mollusk called a whelk from a mean height of about 5 meters. By analyzing a data set, students investigate and create a model for the relationship between the height of the drop and the number of drops.

Graph of a Parabola (Conic Section)
http://www.desmos.co...
This is an interactive graph of a parabola as a conic section. The vertex, focus, and directrix of the parabola are displayed on the graph. A movable slider can change the distance between the focus and the vertex to explore the effect this distance has on the graph.
