In this self-paced tutorial, learners analyze data to understand the relative influence of solar variability on today's climate to determine whether changes in incoming solar radiation can explain all or part of the warming trend we have seen in... (View More)

In this data analysis activity, students compare near surface temperature at the time of the solstices in two different hemispheres, and see how the tilt of the Earth's axis in relationship to the Sun contributes to temperature differences across... (View More)

Keywords: Tilt; Earth axis; Solstice
Audience: Middle school, High school
Materials Cost: Free per student

In this problem-based learning activity, learners explore the significance of sunspots on the Earth's climate. Sunspots are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. During... (View More)

How effective would solar cells be in any particular area of the United States? In this activity, students answer that question by analyzing graphs of incoming solar radiation. Students will download two solar radiation graphs, one based on latitude... (View More)

This 24 minute planetarium show teaches about meteors, meteorites, asteroids, and comets. The show was created for fulldome theaters, but is also available on DVD to be shown in flat version for TVs and computer monitors, and can be freely viewed... (View More)

Keywords: Meteors; Meteorites
Audience: Informal education
Materials Cost: $5 - $10

In this problem set, learners will analyze an altitude graph of the International Space Station to understand its rate of altitude loss as a result of atmospheric drag and solar activity. Answer key is provided. This is part of Earth Math: A Brief... (View More)

In this problem set, learners will analyze a graph of solar irradiance since 1610. Answer key is provided. They will consider average insolation, percent changes and the link between irradiance and climate change. This is part of Earth Math: A Brief... (View More)

This activity is designed to introduce students to planetary geologic features and processes. First, students will use NASA satellite images to identify geologic surface features on the "Blue Marble" (Earth), and will explore the connection between... (View More)

In this activity, students are introduced to the concept of remote sensing. In the course of this experiment, students will investigate heat conduction on two surfaces and understand the application of these techniques to spacecraft investigations... (View More)

Net Radiative Flux (NRF) is used to determine the flow of solar energy in and out of the Earth system. NRF is influenced by seasonal variations related to the tilt of the Earth's axis and degree of cloud cover as well as Earth’s surface features.... (View More)
