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.

Title: Mars Earth Orbit - Model      Add Bookmark
Description: This student interactive, from Illuminations, uses circular orbits to approximate the paths of Mars and Earth. Users can view a diagram depicting the orbits of both planets around the sun and see how their relationship to one another changes as they complete their orbits.

Subject: Science
Title: Mars Earth Orbit - Actual      Add Bookmark
Description: This student interactive, from Illuminations, uses the actual distances and speeds of the planets to simulate the relative positions of Earth and Mars. Because the center of the Earth s orbit is approximately the Sun and the center of Mars orbit is about 22 million miles from the Sun, the orbits of the two planets are closer to one another on one side of the Sun than on the other side. The interactive illustrates this fact.

Title: Weather and Agriculture      Add Bookmark
Description: In this Xpeditions lesson, students research, discuss, and write reports on the relationship between climate and agriculture. They pretend that they've just purchased farms in specific parts of the United States and investigate that region's weather and climate in order to maximize the chances that their farms succeed.
