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 activity explores how ancient Sun observers made use of natural and built structures to mark solar alignments observed at different times of the year, particularly around the solstices and equinoxes. In Part 1, the teacher prepares a horizon... (View More) table that represents the Earth’s horizon. In Part 2, students create functioning models of an existing ancient solar observatory or design their own observatory. In Part 3, students test their model using the horizon table and a flashlight as the Sun. The lesson includes discussion questions, background information about Maya astronomy, a checklist for science notebook write-ups, and a math extension activity that measures shadows. This activity is the seventh lesson in the Ancient Eyes Look to the Skies curriculum. (View Less)
In this activity, students begin learning about archaeoastronomy much as the first skywatchers began learning about the sky: by observing and wondering. Students observe photographs and drawings of petroglyphs, pictographs, and natural and... (View More) human-made structures believed to be ancient observatories or of relevance to ancient astronomies and astronomers. They discuss and record observations (I notice…) and questions (I wonder…) on chart paper. This activity, which is the first in the Ancient Eyes Look to the Skies curriculum, allows teachers to discover students' prior experience and knowledge, thus helping them personalize the other activities in the curriculum for their classes.

In this activity, students learn the basics of the horizon, direction and the rising and settings of the Sun and stars by making a schoolyard "medicine wheel" with sidewalk chalk on playground asphalt. Medicine wheels are stone rings constructed by... (View More) the Plains people of North America which may have been used as a calendar system based on observations of objects in the sky. This activity requires a flat area at least 6 meters across – preferably asphalt or concrete – that has a good view of the sky. It can be done as a whole class activity. Part 1 of this activity involves constructing the medicine wheel (about 10-15 minutes). Part 2 of this activity involves making ongoing observations throughout the year at noon (about 10-15 minutes for each observation). Part 3 involves making observations from the wheel during after-school hours to observe the rising or setting points of stars, the Sun and Moon. Discussion questions, background information and a math extension activity are included. This activity is the second lesson in the Ancient Eyes Look to the Skies curriculum 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)
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.

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)
