Digital Library for Earth System Education (DLESE)
(26.580 recursos)
The Digital Library for Earth System Education (DLESE) is a grassroots, community-based effort involving teachers, students, and scientists working together to create a library of educational resources and services to support Earth system science education. DLESE supports Earth system science education by providing access to high-quality collections of educational resources; access to Earth data sets and imagery; support services to help educators and learners effectively create, use, and share educational resources; and communication networks to facilitate interactions and collaborations across all dimensions of Earth system education.

SIMPLE Science - Earth and Space Science Home
The Simplified Image Management and Processing Learning Environment for Science (SIMPLE Science) aims to create resources for middle school that emphasize image processing and analysis techniques while at the same time meet educational standards. The collection features tutorials that (a)guide students through case studies replicating research conducted by leading imaging scientists and (b)explain key concepts in imaging science. This is the entry for the Earth and space science section. Educational levels: Middle school

Hole in the Sky
In this lesson, students use a Web-based customized version of ImageJ to examine images of atmospheric ozone levels over the South Pole to determine the months of lowest ozone levels and changes in ozone levels since 1979. Some of the causes for the decline in ozone are introduced. Educational levels: Middle school
3.
Snow and Ice: The Sequel
In this lesson, learners use WebImage, a Web-based customized version of ImageJ, to investigate changes in snow cover and sea ice in the Northern Hemisphere over a period of 24 years. The images are obtained from satellite measurements of visible and microwave radiation. The lesson follows from Snow and Ice: A Hemispherical View. Educational levels: Middle school
4.
Planetary Gallery
In this lesson, learners examine images of the Sun, the Moon, Pluto, and all eight planets in the Solar System. Students determine the diameter of each object from a scale bar provided with each image and then rank the objects in order of size. Using a customized version of ImageJ running as an applet, students are introduced to setting scale and units of measurement. Educational levels: Middle school
5.
Snow and Ice: A Hemispherical View
In this lesson, learners compare snow and ice cover in the Northern Hemisphere over a period of two years. The images are obtained from measurements of visible and microwave radiation taken by satellites and sent back to Earth and are analyzed with a customized version of ImageJ running as an applet within a browser. Educational levels: Middle school
6.
Hurricane Central
In this lesson, learners use a Web-based version of ImageJ to examine images of Hurricane Katrina as it moved through the Gulf of Mexico in August 2005. Students explore infrared radiation, water vapor, and visible radiation, and use images captured by the NOAA GOES satellite to plot and measure the path of Katrina. Educational levels: Middle school
7.
Bits of Bugs
In this lesson, learners measure the lengths of various insect body parts from scanning electron micrographs using WebImage, a Web-based customized version of ImageJ. The lesson introduces students to setting scale in making the measurements and to units of measurement, as well as entomology. Educational levels: Middle school
8.
Taking Temperatures
In this lesson, learners investigate endothermy and ectothermy. Four sets of images measuring infrared radiation are provided and, using a Web-based, customized version of ImageJ, students compare body temperatures of a snake and rat before and after exposure under a heat lamp. Educational levels: Middle school
9.
Slice of Pi
This lesson uses WebImage, a Web-based customized version of ImageJ, to investigate the relationship between the circumference and diameter of a circle. Images of circular objects are provided, and, by measuring diameter and circumference, students are able to obtain an approximate value of Pi. They also explore the history behind Pi and how to find its value. Educational levels: Middle school
