This article describes the work being done by scientists to determine the origin of water found in Earth's oceans. A supplemental exploration of the Herschel Space Observatory is included. The article is targeted to children ages 10-12.
This question is addressed through a series of questions and answers, each providing related introductory information such as how climate change is studied, the history of Earth’s climate, and the effects of climate change on Earth’s geology and... (View More) biology. The Climate Kids website is a NASA education resource featuring articles, videos, images and games focused on the science of climate change. (View Less)
Unit one of the "Carbon Connections: The Carbon Cycle and the Science of Climate" curriculum introduces the role of carbon (as carbon dioxide) as an atmospheric indicator. Students examine the impact of geologic and climatic history on current... (View More) climate by using computer models, measurements and the geologic record of past climate indicators. The unit contains five lessons entitled: Carbon Fizz, Carbon from the Past, Carbon Forcing, Global Connections, and Core Connections. Each of the five lessons includes focus questions, hands-on activities, virtual field trips, and interactive models. (View Less)
This textbook chapter introduces the buffalo as a keystone species, and describes the environmental impacts of its near extinction, including today’s predominance of non-native species in the Great Plains. Human activities that contribute to... (View More) species extinction are addressed. Students graph historical sightings of buffalo, and calculate the number of buffalo killed for bone used in refining sugar and fertilizer and in the production of bone china. The resource includes a link to current news articles and a teacher's guide. This is the second chapter in the unit, Losing Biodiversity, examining the endangerment and extinction of entire species of plants and animals throughout the world due to human actions. The resource is part of Global System Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.

This introductory textbook chapter presents data demonstrating decreased global biodiversity and its link to human activity. The resource includes a field-based student investigation of local biodiversity, links to current news articles, and an... (View More) essay-based unit assessment. A teacher's guide supports classroom use. This is chapter 1 in the unit, Losing Biodiversity, is about the endangerment and extinction of entire species of plants and animals throughout the world due to human actions. The resource is part of Global System Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.

In this problem set, learners will analyze a table of the length of day (hours) and the number of days per year on Earth in past eras. They will calculate future values, plot some of the data and identify the rate of increase. Answer key is... (View More) provided.

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) those features and the geologic processes that created them. Using that information, students will then compare and discuss similar features on images from other planets. Included are the following materials: teacher's guide (with reference and resource information), student's guide (with activity sheets), and multiple cards of planetary images. Note that the range of targeted grade levels is quite broad; however, explicit adaptations for younger students are highlighted throughout the teacher's guide. (View Less)

Remote sensing detects both human and physical features by using seven distinct image elements: tone, shape, size, pattern, texture, shadow and association. Students are introduced to each of these elements individually through images, descriptions... (View More) and related questions. Then, by assimilating and applying their knowledge, they interpret the remotely sensed image of an unidentified location. The URL opens to the investigation directory, with links to teacher and student materials, lesson extensions, resources, teaching tips, and assessment strategies. This is Investigation 2 of three found in the Grades 5-8 Module 4 of Mission Geography. The Mission Geography curriculum integrates data and images from NASA missions with the National Geography Standards. Each of the three investigations in Module 4, while related, can be done independently. (View Less)
Remote sensing, using Thermal Infrared Multispectral Scanner (TIMS) data, has lead to the discovery of previously unknown roads in the canyon area of New Mexico once occupied by the Anasazi culture. Students will use those images, along with maps... (View More) and photos, to observe the roads and surrounding area. Students will then compare the value of each media (image, map, photo) in uncovering and interpreting archeological information. Emphasis is placed on the map/image reading skills of direction and scale.
