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 is part of Earth Math: A Brief Mathematical Guide to Earth Science and Climate Change. (View Less)
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)

This site contains a variety of educational and supporting materials related to microbiology. Information is provided about microorganisms, extremophiles and extreme habitats, as well as links to online resources that provide information about the... (View More) ecology, diversity and evolution of micro-organisms. (View Less)
This is a lesson about the important materials brought to Earth by carbonaceous chondrites. Learners will conduct experiments that simulate how the carbon material and water from carbonaceous chondrites may have helped early life on Earth, grow... (View More) yeast in mediums that represent carbonaceous chondrite material, and recognize that carbonaceous chondrite meteorites contain amino acids, the buildng blocks of life. Advanced preparation and procedural tips are included. This is lesson 12 of 19 in Exploring Meteorite Mysteries. (View Less)

This is a lesson about discerning fact and fiction in news articles. Learners will read tabloid articles about meteorites and decide if the information is fact or fiction. Questions, extensions, and advanced preparation and procedural tips are... (View More) included. This is lesson 19 of 19 in Exploring Meteorite Mysteries. (View Less)
This is a lesson about the effects of large impacts. Learners will use critical thinking skills to evaluate and apply data from a narrative to a scientific selection process, will demonstrate or visualize simulations of some of the effects of a huge... (View More) impact, and will write a point of view narrative. Materials and vocabulary lists, and advanced preparation and procedural tips are included. This is lesson 14 of 19 in Exploring Meteorite Mysteries. (View Less)
This is a lesson about locating impact craters on Earth using longitude, latitude, and maps. Learners will observe impact craters on Earth and other solar system bodies, discuss geologic forces that have erased much of the evidence of past impacts,... (View More) locate existing and potential impact sites, and plan the necessary research (including a field work plan and request for funding) to investigate and verify their observations. Activities, a locator map, vocabulary words, and experimental extensions are included. This is lesson 7 of 19 in Exploring Meteorite Mysteries. (View Less)
