Colored beads and string are used to create a model of the solar system in order to explore size and distance relationships among planets. A second model for comparing planetary sizes uses common types of fruits and seeds(either actual fruits or the... (View More)

Learners will experiment to create impact craters and examine the associated features. Then they observe images of lunar craters and explore how the mass, shape, velocity, and angle of impactors affects the size and shape of the crater. This... (View More)

In this lesson, students read the original paper written by Henrietta Leavitt in which she compared the apparent brightness and period of Cepheid variable stars. The students prepare graphs from numerical data, just as she did, and compare their... (View More)

In this activity, learners discover new perspectives on geothermal features, such as geysers, mudpots, hot springs, and hot spring terraces by exploring infrared images. Learners will gain an understanding of infrared light and infrared imaging, as... (View More)

Each student will explore three activities that promote understanding of and respect for soil. They will generate responses to the following questions: "What makes up soil?" and "What lives in the soil?" Next the students will watch a demonstration... (View More)

In this activity, students describe the characteristics of different types of galaxies (spiral, elliptical, barred spiral, peculiar, or irregular) in their own words. They also classify galaxies seen in the Hubble Deep Field. This is activity two in... (View More)

In this activity, students explore the idea of classifying objects. They start by giving examples of objects that can be classified in everyday life and in science. They then characterize and classify a set of galaxies using their own scheme, and... (View More)
