Interstellar Boundary Explorer Lithograph

This is a lithograph that outlines the major mission highlights of the Interstellar Boundary Explorer, or IBEX, mission, a Small Explorer Earth-orbiting spacecraft that is designed to map the distant boundary between the solar wind from our Sun and the interstellar medium, the material between th

Carbon Dioxide- Where Does it All Go?

In this problem set, learners will use a diagram of carbon fluxes, which shows the sources that contribute to current atmospheric carbon dioxide levels, to answer a series of questions. Answer key is provided.

Hunting Icebergs: Sizing up Icebergs

This self-paced, interactive tutorial enables learners to identify and measure iceberg size from remotely-sensed satellite images.

ClimateBits: Albedo

This video explains albedo - the concept that the brightness of the Earth system (atmosphere, ocean, and land surfaces) determines how much incoming solar energy is immediately reflected back to space.

Atmosphere and Temperature

Learners will use the inquiry process to explore the affect of atmosphere on the temperature of a planet. They create a model of the system to test. They then create a concept map of the planetary temperature system.

Astro101 Slide Set: Fermi Telescope Discovers Milky Way Bubbles

This slide set focuses on the Fermi Mission's discovery of bubbles emanating from the core of the Milky Way galaxy. It is one of a series of short, topical presentations on new developments from NASA astrophysics missions, relevant to introductory astronomy topics.

Why (Not) So Blue?

Using water to represent the atmosphere and milk droplets to represent aerosols, students make predictions and conduct investigations to discover how different aerosol concentrations affect atmospheric color and visibility.

Graphing the Globe

This is an activity about the relation between day length and temperature. In one team, learners will create and analyze a graph of hours of sunlight versus month of the year for a number of latitudes. In another team, learners will graph temperature versus month for the same latitudes.

Dancing in the Night Sky

This is an activity about the Aurora Borealis or Northern Lights. Learners will plot the Auroral Oval in the northern hemisphere and determine the height of the northern lights using Carl Stormer's triangulation method.

Investigating the Invisible

In this open inquiry activity introducing concepts of remote sensing, students will discuss and research different invisible phenomena. They will then test and verify the existence of selected invisible phenomena by using measurement or detection devices.
