This is a National Geographic short video that briefly describes how succulent plants in the South African Karoo biome are dying off due to changes in climate.

Through two lessons and five activities, students explore the structure and function of cell membranes. Specific transport functions, including active and passive transport, are presented. In the legacy cycle tradition, students are motivated with a Grand Challenge question. As they study the ingress and egress of particles through membranes, students learn about quantum dots and biotechnology through the concept of intracellular engineering.

Students are presented with a real-life problem as a challenge to investigate, research and solve. Specifically, they are asked to investigate why salt water helps a sore throat, and how engineers apply this understanding to solve other problems. Students read a medical journal article and listen to an audio talk by Dr. Z. L. Wang to learn more about quantum dots. After students reflect and respond to the challenge question, they conduct the associated activity to perform journaling and brainstorming.

This issue of the free online magazine, Beyond Penguins and Polar Bears, examines physical science concepts, such as heat, conductors, and insulation, and applies this knowledge to the animals and people in the Arctic and Antarctica.

This article features children's literature about heat, temperature, and adaptations and behaviors that allow animals and people to survive in the polar regions.

This video adapted from Texas Parks and Wildlife Department describes how humans are helping restore safe nesting grounds for the critically endangered Kemp's ridley sea turtle to ensure its successful repopulation.

This article provides an overview of scientific inquiry and how citizen science programs run by the Cornell Lab of Ornithology provide opportunities for inquiry about birds.

Children will investigate leaves by observing, playing a game, sorting and journaling in a science notebook.

LIMSwiki is a collaborative wiki dedicated to the scientific community, featuring organized, documented, and up-to-date content regarding all aspects of laboratory informatics, bioinformatics, and health informatics. LIMSwiki also strives to maintain relevant knowledge about laboratory equipment as well as commercial and open-source software likely to be used in a laboratory setting. This also includes the vendors of such equipment and software.

This Evolution video segment describes how the famous track fossils known as the Laetoli footprints might have been formed and what they can reveal about the creatures who left them.

This article lists some of the characteristics of dyslexia and dysgraphia at the preschool to upper-elementary school levels and identifies teaching strategies that support all students' learning.

In this video profile produced for Teachers' Domain, meet La'ona DeWilde, an environmental biologist who integrates her Athabascan heritage and her Western scientific training to help remote Alaskan villages address environmental issues.

Create a laser by pumping the chamber with a photon beam. Manage the energy states of the laser's atoms to control its output.

This activity is a group activity where students investigate leaves and sort them based on established criteria.

This is a classroom activity where students will make plant rubbings and plant pressings of Minnesota plants.

This activity is a field investigation where students compare leaves, share observations and develop an investigable question to be explored by the class in small groups.

This online article is from the Museum's Science Explorations, a collaboration between AMNH and Scholastic designed to promote science literacy. Written for students in grades 3-6, this article from SuperScience magazine is an interview with AMNH herpetologist Darrel Frost, in which he discusses the upcoming Lizards & Snakes: Alive exhibition. There is a hands-on activity, Create an Exhibit, that challenges students to design a museum exhibit that includes lizards and snakes

Learning about Antarctica's past can give K-Grade 5 teachers and students lessons in geology, climate, and ecology along with literacy experiences in sequencing and time lines. The author identifies online resources for both adults and younger learners. A three-section unit plan begins with sequencing events and follows with earth's history over billions of years and the records found in rocks and fossils. The article appears in the free, online magazine Beyond Penguins and Polar Bears.

This activity is a classroom introduction to bird migration. Students will acquire new vocabulary, sharpen their map skills, and discover the scientific reasons some birds migrate.

This issue of the free online magazine, Beyond Penguins and Polar Bears, explore how to use fossils and artifacts (scientific clues) to learn about the polar regions' past. Targeted literacy skills include making inferences, and using context clues to define new vocabulary.
