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 a lesson about light in the outer solar system. Learners will demonstrate the effect of the inverse square law of illumination with distance and connect this to the functioning of solar panels at Saturn. Requires a silicon solar cell... (View More)

Learners will measure temperature of two different surfaces; sand and stone; on a sunny day, make a series of temperature measurements, and plot the results. Extensions include experimenting with different materials, using temperature sensors and... (View More)

This activity is about crater formation in the solar system. Through a simulation using mud and other materials, learners will observe crater formation and identify the distinctive features of impact sites. A diagram with crater features labeled is... (View More)

Learners will make a model of the Moon's surface and consider the geologic processes and rocks of each area. This activity is in Unit 2 of the Exploring the Moon teachers guide, which is designed for use especially, but not exclusively, with the... (View More)

Learners will research and document some of the requirements for mounting an expedition to an asteroid; actively explore potential resources available to space travelers through research, assessment, team cooperation, and exploration simulations;... (View More)

Students will collect samples of particles in the air on simple slides they make themselves. They will classify, count and chart their findings, draw conclusions, make predictions, and compare their findings to other available data. Supplies needed... (View More)

In this introductory global change investigation, students gather and record visual and written data from their surroundings, and through analysis, show how the sampling window chosen for examination can affect an outcome, sometimes resulting in... (View More)
