## 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.

## SciJinks: Gallery of Oceans

This gallery showcases a wide range of ocean imagery - from above and below the surface. SciJinks is a joint NASA/NOAA educational website targeting middle school-aged children and their educators. It explores weather and Earth science through articles, videos, images, and games.

## SciJinks: When Disaster Strikes

This resource includes a brief article and an interactive portion on emergency preparedness. SciJinks is a joint NASA/NOAA educational website targeting middle school-aged children and their educators. It explores weather and Earth science through articles, videos, images, and games.

## The Most Powerful Explosions in the Universe

One of the greatest mysteries of all is what causes gamma ray bursts. These bursts are the most powerful explosions in the Universe and occur about once a day. Their origin is unknown, although there are several theories.

## Graphs and Functions

Students will learn about NASA's Radiation Belt Storm Probes (RBSP), Earth's van Allen Radiation Belts, and space weather through reading a NASA press release and viewing a NASA eClips™ video segment.

## Down to Earth: Colors

Students identify the actual colors of objects bathed in monochromatic light and learn how three colors of light can be combined to produce colors ranging from black to white. Students see how space observatories make use of monochromatic filters to collect data on the color of objects in space.

## NASA eClips™ Real World: What is Soil Moisture?

In this video clip, see how NASA measures soil moisture from space with the Soil Moisture Active Passive Mission (SMAP). Learn to calculate soil moisture in your own backyard and discover the real world applications for this data. NASA eClips™ are short, relevant educational video segments.

## Constructing a Barometer

This experimental activity is designed to develop a basic understanding of the relationship between temperature and pressure and that a barometer can be constructed to detect this relationship.
