This lesson is an introduction to the history and use of the scientific concept of the mole.
Dieter Hartmann, a high-energy physicist, presents a story-based lesson on the science of Gamma-Ray astronomy. The lesson focuses on gamma-ray bursts; examining their sources, types, and links to the origin and evolution of the Universe. The story-based format of the lesson also provides insights into the nature of science. Students answer questions based on the reading guide. A list of supplemental websites is also included.
This story-based lesson presents information on the early investigation into solar and cosmic X-rays, as well as the scientists working in pursuit of X-ray detection and imaging, that set the stage for a program of space-based astronomy. The lesson is narrated by Dr. Herbert Friedman, and includes information on his work, as well as his childhood, home life, and interests while a college student.
In this hands-on lesson, students measure the effect of distance and inclination on the amount of heat felt by an object and apply this experiment to building an understanding of seasonality. In Part 1, the students set up two thermometers at different distances from a light bulb and record their temperatures to determine how distance from a heat source affects temperature. In Part 2, students construct a device designed to measure the temperature as a function of viewing angle toward the Sun by placing a thermometer inside a black construction paper sleeve, and placing the device at different angles toward the Sun. They then explain how distance and inclination affect heat and identify situations where these concepts apply, such as the seasons on Earth and the NASA Mercury MESSENGER mission.
Of all the animals in the oceans, the hammerhead shark may be one of the strangest looking. The exact purpose of the wide, flat head is a mystery, but several theories abound. In this video, we travel to the shark-infested waters of the Galapagos in Ecuador and to a research station in Hawaii to learn about the unusual habits of these sinister-looking sharks. Jonathan swims in schools of hundreds of hammerheads, and yet the sharks ignore him. What are the sharks up to? Please see the accompanying study guide for educational objectives and discussion points.
This activity is about the study of planetary samples. Learners will use samples of crustal material to sort, classify, and make observations about an unknown planet. From their observations, students will interpret the geologic history of their mystery planet and make inferences about past life or the potential for life on the "Mystery" planet. The lesson models scientific inquiry using the 5E instructional model and includes teacher notes and vocabulary.
This poster highlights a variety of Earth science careers, featuring short biographies from 13 NASA Earth explorers, including scientists, engineers, educators and more. The poster also includes information about NASA's unique perspective on the Earth, one educator's story about how he uses NASA Earth science data and materials in his middle school classroom, and a collection of classroom activity suggestions.
Navigational tools and methods of early voyagers provide the background and contrast to the satellite images and models used today. Students complete mapping activities based on historical data from Columbus and Blith. Students will also use a computer model of ocean currents to investigate the movement of objects drifting on the ocean surface. Note that this is lesson one of five on the Ocean Motion website. Each lesson investigates ocean surface circulation using satellite and model data and can be done independently. See Related URL's for links to the Ocean Motion Website which provide science background information, data resources, teacher material, student guides and a lesson matrix.
This inquiry leads students through an investigation of the problem solving that goes into the formation of a government, and more specifically, the legislative branch. Students will examine what went into the formation of our federal government’s bicameral legislature, why Nebraska broke the mold and is our nation’s only unicameral legislature and examine if this system is still serving Nebraska appropriately.

Bar chart of countries ranked by their net migration flow as of 2005. While the highest net in-flow is generally into large rich countries (USA, Spain, Germany etc.) Afghanistan had the second highest net inflow thanks to returning refugees.
The Champlain Lowlands tour is part of the New York Landscape Regions Collection of Google Earth tours, created by a group of New York State science educators. This tour includes views of the gorge of the Ausable River, cut through Late Cambrian Potsdam Sandstone, and the geology of the Champlain Thrust Fault, a low angle thrust fault formed as the proto-Atlantic Ocean closed during the Taconic Oregeny. When it was still connected to the ocean, Lake Champlain was home to whales, whose fossils are now entombed in the lake sediments. The tour also includes classroom activities for students.
This video introduces phytoplankton - the base of the marine food web, the source of half of the oxygen on Earth, and an important remover of CO2 from the atmosphere. The video also explains how satellites are used to monitor phytoplankton and how warming waters and acidification negatively affect phytoplankton.
The Key Terms resource is provided in .docx format. It includes terms extracted directly from the textbook and organized by chapter. Each key term is bolded and followed by its definition in context.
Indigenous people have been forming governments and building nations for hundreds of years. The formal treaties that were made between the first colonists and the First Peoples of America was nothing new to the native communities as they had already had treaties in place between other tribes.
The “Own It!”Handbook for Ages 11-16 is the guide book for a transformative after-school, trauma-informed enrichment program. It provides a series of lessons & activities that nurture academic skills, personal growth and leadership. It uses history to connect our past to our future, as part of the Own Your History® (OYH) Collection.Our inheritances from family history and from living in the United States provide the starting point for our personal journeys. Our individual stories are part of a complex American history. We each can choose consciously to write our life story and work for a greater future. But Own It! is not “school” and it differs from traditional approaches to history. Own It! helps students learn more about themselves, as well as their community and the country. Own It! enhances students’ engagement in being creative, making things happen, and achieving goals. Its mission is to help them step up and enrich their lives, especially by understanding that they live in history.
This is an activity about detecting elements by using light. Learners will develop and apply methods to identify and interpret patterns to the identification of fingerprints. They look at fingerprints of their classmates, snowflakes, and finally “spectral fingerprints” of elements. They learn to identify each image as unique, yet part of a group containing recognizable similarities. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System.
The Pedro Albizu Campos Digital Resource Collection contains digitized images of all of the archival documents of Pedro Albizu Campos maintained by Harvard University Archives (HUA). The collection focuses on 1912-1923 (the date of Albizu’s official Harvard Law School degree conferral). The digital images are of every single document of Pedro Albizu Campos from the University of Vermont, Harvard College, and Harvard Law School. It includes newspaper clippings in Albizu’s alum file and Laura Meneses del Carpio, wife of Albizu, maintained by Radcliffe College. The collection includes Spanish translations of most digital images and English text for most handwritten letters and notes.
In this learning activity, students compare changes in insolation with changes in surface temperature in the polar regions using scientific visualizations of global data sets. Links to readings related to the shrinking ice cap and albedo are included. This is part 1 of a four-part activity on polar science. Extension activities examining air and sea surface temperature in relation to changing Earth albedo are included. This activity is one of several learning activities connected with the 2007 GLOBE Earth system poster.
This inquiry leads students through an investigation of different forms of political participation and their effectiveness through the context of the Civil War.
