This issue of the free online magazine, Beyond Penguins and Polar Bears, contains content knowledge and instructional resources about icebergs and glaciers and the scientific principles of density and buoyancy.

This article discusses the research-based strategy of identifying similarities and differences and provides links to web sites to develop teacher's content knowledge.

In this video segment from The Secret of Life Teaching Modules: "Nothing to Sneeze At: Viruses," watch as a virus attacks a cell, and learn how the immune system reacts to this onslaught.

This is a lesson plan for students to show their understanding of the life cycle of a plant or animal by creating an infographic using Google Drawings. The lesson gives links and information to teach both of these and then provides examples, graphic organizers, and rubrics to be able guide you through using the infographic as an assessment tool. The lesson is targeted for 3rd graders with a simplified rubric they can use themselves or with a partner or teacher. 

This video segment adapted from NOVA illustrates why carbon is at the center of life on Earth. It also asks whether carbon-based life might exist on other planets.

This video segment from NOVA: "The Sea Behind the Dunes" explores the community of organisms that exists in the New England tidal marsh.

Interview an Organism gives students the opportunity to enter the world of an organism. Students slow down and have a “conversation” with an organism of their choosing, asking questions that can be answered through more observation while paying attention to its surroundings and the scale of its world. It helps take students to a “next level” of observing and questioning as they learn to ask themselves questions that lead them to make deeper observations. In the process, they get to know their chosen organism.

In this Exploration Routine, students search for interesting organisms and observe them. Each pair of students chooses an organism to study, comes up with questions about the organism’s appearance and structures, while attempting to answer each one through observations. Then they move on to more probing questions about the organism’s behavior, ecosystem, and relationships to other organisms. Afterwards, students share with other pairs and then with the whole group.

This course samples the wide variety of bioengineering options for students who plan to major in one of the undergraduate Engineering degree programs. The beginning lectures describe the science basis for bioengineering with particular emphasis on molecular cell biology and systems biology.

Students design and conduct simple experiments using elodea (aquatic plant sold in pet stores) and Bromthymol blue to determine whether plants consume or release carbon dioxide in the process of photosynthesis. Students will record their data which will be used to conclude whether carbon dioxide was consumed or released by the elodea. Through class discussion of student data, students will learn that carbon dioxide was consumed during photosynthesis.

Students work in pairs to compare five aspects of an organism that reproduces sexually, asexually, or both sexually and asexually. The activity comes with a chart for the students to fill out and with information sheets on twelve organisms. As a class, students share their comparisons and generate a list of general characteristics for each mode of reproduction and then discuss the advantages and disadvantages of both. Included in the discussion are reproductive mechanisms and genetic variation.

In this video segment from Greater Boston, learn about conflicting theories regarding the cause of autism.

This video, adapted from material provided by the ECHO partners, provides a portrait of IŰ__ŒóíŠupiaq whaling as a community activity, as told through the story of one hunt.

Dried meat has long been a staple for Indigenous communities throughout the world. The process and practice of using time, heat, and seasonings to create something that is safe, satisfying and sustainable is a delicate balance that Indigenous people have mastered for Millenia. And that's science!

This resource is a Nearpod lesson about analyzing shifting population trends of American Kestrel. It was created as part of the Reimagine Teaching program by HawkWatch International. HawkWatch International is a non-profit organization in Salt Lake City, Utah that works to protect raptors and our shared environment through scientific research and public education.

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.

This lesson uses the fundamentals of protein synthesis as a context for investigating the closest living relative to Tyrannosaurus rex and evaluating whether or not paleontologist and dinosaur expert, Jack Horner, will be able to "create" live dinosaurs in the lab. The first objective is for students to be able to access and properly utilize the NIH's protein sequence database to perform a BLAST, using biochemical evidence to determine T rex's closest living relative. The second objective is for students to be able to explain and evaluate Jack Horner's plans for creating live dinosaurs in the lab. The main prerequisite for the lesson is a basic understanding of protein synthesis, or the flow of information in the cell from DNA to RNA during transcription and then from RNA to protein during translation

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.

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.
