Inquiry based research on endangered animals.
Understanding the different levels of animals in trouble.

The lessons in this issue of Smithsonian in Your Classroom introduce the work of botanists and botanical illustrators, specifically their race to make records of endangered plant species around the world. “Very little of the world’s flora has been fully studied,” says one Smithsonian botanist, “and time is running out.” In the first lesson, students gets to know six endangered plants. They examine illustrations, photographs, and dried specimens of the plants as they consider this question: If a scientist can take a picture of a plant, are there advantages in having an illustration? They go on to consider some of the big questions that botanists themselves must ask: Which of these species are most in need of conservation efforts? Are any of these plants more worth saving than others?In the second lesson, the students try their own hands at botanical illustration, following the methods of a Smithsonian staff illustrator. All that is required for the lesson are pencils, markers, tracing paper, and access to a photocopier.

Students are introduced to the work of botanists and botanical illustrators, and specifically to their race to make records of endangered plant species around the world. Students examine illustrations, photographs, and dried specimens of endangered plants and consider the conservation value of an illustration over a photographic image. In a second session, students try their own hands at botanical illustration and follow the methods of a Smithsonian staff illustrator. Pencils, markers, tracing paper, and access to a photocopier are required.

This article from the free online magazine Beyond Weather and the Water Cycle provides appropriate science lessons for Grades K-5. The focus is on acquainting young learners with climate-change concepts that are not too complex for their grade level and will not frighten them. In each issue, the magazine develops articles around one of the seven essential principles of climate science. The author believes early lessons about water availability and extreme weather events will prepare students for complex climate concepts they will encounter in later grades.

The Progressive Era's most controversial environmental issue was the 1908-1913 struggle over federal government approval for building the Hetch Hetchy dam in a remote corner of federally-owned land in California's Yosemite National Park. The city of San Francisco, rebuilding after the devastating 1906 earthquake, believed the dam was necessary to meet its burgeoning needs for reliable supplies of water and electricity. At Congressional hearings on Hetch Hetchy held in 1913, supporters of the plan like Gifford Pinchot, the first Chief Forester of the United States and a noted environmentalist, argued that conservation of natural resources was best achieved through management of the wilderness. Preservationist and Sierra Club founder John Muir did not testify before Congress, but he argued against the Hetch Hetchy plan in this excerpt from his 1912 book, The Yosemite. In the end Congress chose management over aesthetics, voting 43-25 (with 29 abstentions) to allow the Hetch Hetchy dam on federal land.

This list of carefully selected books for grades K-5 highlights nonfiction about climate proxies, those preserved physical characteristics, such as fossils, that scientists use to reconstruct past climates. Also highlighted are a few books that provide information about two past climatic events -- the last ice age and the Dust Bowl. In each issue of the free, online magazine Beyond Weather and the Water Cycle, the virtual bookshelf recommends books that accurately portray the theme drawn from the principles of climate sciences.

Use this board game to introduce the concepts of energy use in our lives and the very real impact that personal choices can have on our energy consumption, energy bills and fuel supply. The game begins as students select cards that define their modes of transportation and home design. The players roll dice and move around the board, landing on "choice" or "situation" blocks and selecting cards that describe consumer choices and real-life events that impact their energy consumption and annual energy bills. As the players pass gasoline stations or energy bill gates, they must pay annual expenses as defined by their original cards, with amounts altered by the choices they've made along the way. Gasoline cards are collected to represent total consumption. Too many gas-guzzling vehicles can result in total depletion of their gasoline supply – at which point everyone must walk or ride the bus. At the end of the game, the players count their remaining dollars to determine the winner. Discussion questions probe the students to interpret what choices they made and which situations they encountered had the most impact on their energy consumption and energy bills. All game board, card and money files are available online free of charge.

Students are introduced to the idea that energy use impacts the environment and our wallets. They discuss different types of renewable and nonrenewable energy sources, as well as the impacts of energy consumption. Through a series of activities, students understand how they use energy and how it is transformed from one type to another. They learn innovative ways engineers conserve energy and how energy can be conserved in their homes.

This course will covers a basic understanding and appreciation of energy efficiency and environmental concepts, basic operating principles of day-to-day energy conversion devices, various options to increase energy efficiency, ways to save energy and money, and ways to save the environment.

The students participate in many demonstrations during the first day of this lesson to learn basic concepts related to the forms and states of energy. This knowledge is then applied the second day as they assess various everyday objects to determine what forms of energy are transformed to accomplish the object's intended task. The students use block diagrams to illustrate the form and state of energy flowing into and out of the process.

This collection uses primary sources to environmental preservation in the Progressive Era. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.

The first great American conservation movement was born during the Progressive Era out of the concern that industrial growth and urban development threatened to extinguish America's wilderness. The era's most controversial environmental issue was the five-year struggle over federal approval for the flooding of a remote corner of federally-owned land in California's Yosemite National Park to build the Hetch Hetchy dam. The city of San Francisco, rebuilding after the devastating 1906 earthquake, believed the dam was necessary to meet its burgeoning needs for reliable supplies of water and electricity. In their 1913 testimony before the House Committee on Public Lands, former San Francisco Mayor James Phelan and Gifford Pinchot, the first Chief Forester of the United States and the most noted conservationist of his generation, put the utilitarian needs of San Francisco's citizens above the aesthetic and moral advantages of leaving Yosemite a pristine wilderness. In the end Congress chose management over aesthetics, voting 43-25 (with 29 abstentions) to allow the Hetch Hetchy dam on federal land.

Faced with the potential of a large expense related to water quality, the Portland (Maine) Water District performed a thorough analysis of their options. Their choice came down to making an investment in conservation or concrete.

Students complete three different activities to evaluate the energy consumption in a household and explore potential ways to reduce that consumption. The focus is on conservation and energy efficient electrical devices and appliances. The lesson reinforces the relationship between power and energy and associated measurements and calculations required to evaluate energy consumption. The lesson provides the students with more concrete information for completing their culminating unit assignment.

Students learn about the human water cycle, or how humans impact the water cycle by settling down in civilizations. Specifically, they learn how people obtain, use and dispose of water. Students also learn about shortages of treated, clean and safe water and learn about ways that engineers address this issue through water conservation and graywater recycling.

In 1840, Unitarian minister George Ripley wrote to the Transcendentalist author Ralph Waldo Emerson in an (unsuccessful) effort to convince him to join, or at least invest in, his planned utopian community, Brook Farm. Founders of antebellum utopian communities attempted to withdraw from what they saw as the hypocrisies and excesses of partisan politics, the inequities inherent in marriage and factory work, the evils of the slave system, and the corruption of cities and to create, in small scale, a more perfect place. Brook Farm began operations in 1841 in West Roxbury, Massachusetts. The Brook farmers lived and dined communally, and divided their time between farm work and artistic and scholarly pursuits. Although other utopian communities, such as Oneida in upstate New York, and Amana, in Iowa, achieved self-sufficiency, Brook Farm ultimately failed. The community never recovered from a devastating fire in 1846, and it closed its doors in 1847.

Tragically, contact between Indians and the Europeans extended beyond just trade goods; the invasion of foreign microbes devastated Indian communities well beyond the coastal region. When John Lawson visited the Carolina interior in the 1690s, he encountered the Congaree people, whose numbers and villages had been dramatically reduced by smallpox and other diseases. In 1660, Lawson, born into a London gentry family and aspiring to a career as a natural scientist, had set sail for the Carolina colony that was founded after the restoration of the British monarchy. He traveled more than a thousand miles as an employee of the colony's proprietors, who were eager to attract additional colonists and foster economic development. Lawson's keen eye for the native and non-native people, flora, and fauna of the region was evidenced in his journal A New Voyage to Carolina, published in 1709.

As eighteenth-century colonists eyed the lands across the Appalachian Mountains for further settlement, they needed explorers and promoters. Daniel Boone was both. Born in Pennsylvania in 1734, he settled his family along the Yadkin River in North Carolina in 1757. A decade later he traveled across the Appalachians to explore and hunt in the rich area around the Kentucky River. Boone and his hunting partners actually shared many values with the local Indians, but the goals of natives and newcomers diverged when permanent settlement occurred. By 1775, Boone was leading settlers through the Cumberland Gap along the Wilderness Road to the stockaded settlement of Boonesborough. He described his most significant trip, which took place between 1769 and 1771, in this selection from his 1784 "autobiography." John Filson, a land speculator and author of Discovery, Settlement and Present State of Kentucke, created Boone's legend as a frontier hero by appending a ghostwritten first person narrative by Boone to his promotional tract. Soon after, Boone abandoned Kentucky because of disputed land claims; he eventually died in Missouri in 1820.
