This is an activity about seasons. Learners will analyze monthly temperature data from various cities around the globe in order to dispel the misconception that the distance between Earth and Sun may be responsible for the seasons. This is Activity... (View More)

Audience: Middle school
Materials Cost: Free per group of students

This is an activity about critical observation skills. Learners will receive an egg to record its features from various vantage points, illustrating their size, shape, and location. They will then try to identify and recognize the surface features... (View More)

This is an activity about the rotation of the Sun. Learners examine images of the Sun taken by the Yohkoh satellite, use a grid overlay to mark the positions of the sunspots, and then calculate the rate at which the spots move to determine the... (View More)

This is an activity about measuring craters using shadows and geometry. Learners will make a model crater and use a light source to make a shadow. When they are familiar with the techniques for estimating depths from shadows, they will apply their... (View More)

Audience: High school

This is a lesson about using craters to indicate the age of a planetary surface. Learners will simulate the process of cratering by using falling water drops to make craters in fine silica sand. Then, they will compare the cratered surfaces they... (View More)

This activity is about astronomical themes. Learners will use a U.S. Atlas or the internet to search for names of cities or natural features named after astronomical objects. Their lists may be used to stimulate discussion or to begin creative... (View More)

This is a lesson about measuring star size. Learners will use eclipsing binary systems to measure star diameters. This is Activity G-8 of Universe at Your Fingertips 2.0: A Collection of Activities and Resources for Teaching Astronomy DVD-ROM, which... (View More)

This is an activity about graph interpretation. Learners will compare, interpret, and discuss four graphs of the speed, temperature, magnetic field strength, and density of a coronal mass ejection as it swept past Earth in 1997. This is the third... (View More)

This is an activity about the solar activity cycle. Learners will construct a graph to identify a pattern of the number of observed sunspots and the number of coronal mass ejections emitted by the Sun over a fifteen year time span. A graphing... (View More)

This is an activity about the movement of a coronal mass ejection. Learners will plot the path of two coronal mass ejections (CMEs), both the distance traveled and the increasing angular width, as they leave the Sun and travel outward through the... (View More)
