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.

Unsung Heroes of Science

In this lesson, students identify and describe unfamiliar scientist heroes who contributed to the field of science until the year 1929.

M101: The Pinwheel Galaxy

The Hubble Space Telescope image of M101 showcasing a spiral galaxy's well-known features is the subject of the M101: A Star-studded Galaxy lithograph. The lithograph text describes the features that are common to all spiral galaxies.

Determining the Altitude of Iridium Flares

This series of example calculations applies basic trigonometry to to calculate the altitude of satellites and Iridium satellite flares.
