LOC has compiled a consortium of primary sources to work in the classroom. Ready-to-use lesson plans, student activities, collection guides and research aids to spread awareness and highlight the Asian Pacific American experience.

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.

Latex, chocolate, soap, and video game software are just a few of the non-traditional materials that have inspired contemporary artists. While they embrace the modern, synthetic and technologically advanced world in which we live, some of materials present significant conservation problems for museum conservators. Gwynne Ryan, a conservator at the Smithsonian's Hirshhorn Museum and Sculpture Garden discusses the challenges museums face with this issue: Should we keep art locked away to make it last? Or let it be experienced as it was intended while accelerating its natural degradation?

This video documents the scope of changes in the Arctic, focusing on the impacts of warming and climate change on the indigenous Inuit population.

In this activity, students calculate temperatures during a time in the geologic record when rapid warming occurred using a well known method called 'leaf-margin analysis.' Students determine the percentage of the species that have leaves with smooth edges, as opposed to toothed, or jagged, edges. Facsimiles of fossil leaves from two collection sites are examined, categorized, and the data is plugged into an equation to provide an estimate of paleotemperature for two sites in the Bighorn Basin. It also introduces students to a Smithsonian scientist who worked on the excavation sites and did the analysis.
