In this activity, students study the range of colors in a visible light spectrum created from either a glass prism or holographic diffraction grating. This activity is in unit 2 of the "Space-Based Astronomy" guide that contains background... (View More)

In this activity, students construct an analytical spectroscope and analyze the spectrum produced when various substances are heated or excited with electricity. This activity is part of Unit 2 in the Space Based Astronomy guide that contains... (View More)

This activity is about the use of spectral data to identify mineral composition on Mars. Working in teams, students will compare and contrast spectra to identify similarities between Earth minerals and those from Mars. A short list of suggested... (View More)

Thermal images of Earth allow for the visualization and analysis of temperature differences. With the aid of ATLAS thermal images of a shopping mall in Huntsville, Alabama, students examine the impact of the addition of buildings and the loss of... (View More)

This investigation introduces students to the phenomena of urban heat islands, areas of higher then normal temperatures associated with populated areas. Using Atlanta, Ga., as the study site, students begin by analyzing the population growth and... (View More)

This is an activity about cratering. Learners will simluate planetary impact craters on a small scale in the classroom. Relationships between mass and velocity (kinetic energy) of the impactor and crater size are explored, both qualitatively and... (View More)

This is an activity about change. Learners will use images of planetary bodies taken over tens of years to look for stable features and changed features on Saturn, Mars, and the Moon. This activity is part of "Ways of Seeing," an interactive,... (View More)

This is an activity about telescopes. Learners will first measure several circles to determine their diameters and calculate their areas. Afterwards, they will cover each circle entirely with pennies and record how many pennies are needed for each... (View More)
