Permafrost is any soil or surface deposit in an Arctic or alpine region at some depth below the surface at which the temperature has remained below zero degrees Celsius (32 degrees Fahrenheit) continuously for a long period of time. The amount of carbon dioxide and methane stored in permafrost is nearly twice the amount in the atmosphere and, as…

Understanding the spatial nature of the world is necessary in everyday life. Not only do people move about in 3D space, but spatial thinking is also important in many science, technology, engineering, and mathematics (STEM) disciplines. This may be especially true in the geosciences, where learners often encounter unique spatial reasoning…

Molecular storytelling combines three-dimensional (3-D) structure visualization, chemical and biological knowledge, and multidisciplinary functional information from various bioinformatics data resources to generate new knowledge. It prepares students for independent and interdisciplinary learning, facile navigation of public databases to gather…

Visualization is the art of turning information--concepts, processes, events, structures, and trends--into images that support our understanding. Carter Emmart is a visualizer of science. He is the director of astrovisualization for the American Museum of Natural History (AMNH). In this interview, Emmart describes what it is like to be a…

This article discusses a creative visualization project to motivate and engage students. Students depict a dinosaur in its ecosystem and include all three elements of the environment: air, land, and water. Students explore scientific content in evolution, natural selection, food webs, ecosystems and geologic time. (Contains 6 figures.)

A new online tool called "Science Pipes" allows students to conduct biodiversity investigations. With this free tool, students create and run analyses that would otherwise require access to unwieldy data sets and the ability to write computer code. Using these data, students can conduct guided inquiries or hypothesis-driven research to…

Of the eight practices of science identified in "A Framework for K-12 Science Education" (NRC 2012), helping students develop and use models has been identified by many as an anchor (Schwarz and Passmore 2012; Windschitl 2012). In instruction, disciplinary core ideas, crosscutting concepts, and scientific practices can be meaningfully…

How can we teach science to English language learners (ELLs) when even our native English speakers have trouble reading the textbook? To help science teachers meet this challenge, this article presents six text-comprehension strategies used by English for Speakers of other Languages (ESOL) teachers: metalinguistic awareness development,…

Classifying a particle requires an understanding of the type of bonding that exists within and among the particles, which requires an understanding of atomic structure and electron configurations, which requires an understanding of the elements of periodic properties, and so on. Rather than getting tangled up in all of these concepts at the start…

Uses different illustrations with simple line drawings in the word "QUIZ" as clues for students prior to taking tests. (YDS)

Physicist James Trefil once describes the universe as "The Spongy Universe," comparing large-scale cosmic structures to the structure of a sponge. The NASA Genesis education module "Cosmic Chemistry: Cosmogony" features the "Spongy Universe" activity in which pairs of students observe a household sponge, making…

Outlining, making data tables, and sequencing events are commonly used for teaching specific topics in science but not as general learning tools. Discusses how the teaching and application of these visual representation techniques helps students realize their usefulness as learning tools and to learn more efficiently. (LZ)

Describes a demonstration designed to teach chemistry definitions. Important chemical terms which specifically related to the demonstration were defined on handouts and distributed to the students for reference during the demonstration. (MLH)

Art provides students a way to visually represent their scientific knowledge and at the same time helps teachers assess student understanding. Examining a drawing allows teachers to scrutinize students' mental model of a science concept. Science can be described as a continuing process of discovering the order and recurring patterns in nature;…

Discusses the need for teaching creative thinking in the classroom. Cites two misconceptions to which the absence of emphasis on creative thinking is attributed. Provides strategies and example activities for promoting the skill. States that these procedures can increase student interest in science. (RT)
