Marine Animals is one of the AMNH Education Department's many collections of specimens and artifacts gathered the world over by explorers and scientists. In its online Discovery Collection form, Marine Animals includes an educator's Guide with suggestions for how to use the Marine Animals Discovery Collection in the classroom.

Oyster Shells is one of the AMNH Education Department's many collections of specimens and artifacts gathered the world over by explorers and scientists. In its online Discovery Collection form, Oyster Shells includes components such as: The Collection -- photographs of 15 specimens with classification and distribution details and an educator's Guide-- with suggestions for how to use the Oyster Shells Discovery Collection in the classroom.

This online activity is part of the museum's Online Field Journal Web site, where young children can explore the wonders of nature with the help of an adult. The challenge here is to compare examples within categories of field evidence. On the opening page, the 11 comparison activities are listed: Seashells, Birds, Insects, Butterflies, Rocks, Leaves, Animal Tracks, Reptiles, Flowers, Fish, and Spiders. On the first page of each comparison activity, there are side-by-side photos of three different objects; students are asked to describe the differences between them. Clicking a photo takes students to a magnified view of the object; this subpage also has additional questions that hone students' observation skills. When students click on the magnified photo, they get a fun fact.

This online activity is part of the museum's Online Field Journal Web site, where young children can explore the wonders of nature with the help of an adult. Here, they get guidance about how to observe nature with printable field journal pages. On the opening page, the 11 field journals are listed: Seashells, Birds, Insects, Butterflies, Rocks, Leaves, Animal Tracks, Reptiles, Flowers, Fish, and Spiders. The first page of each field journal activity includes instructions designed to focus the exploration, along with questions to think about. The field journal, which is a printable page, has places to record a name, the date, weather conditions, and written and illustrated observations.

This course presents finite element theory and methods for general linear and nonlinear analyses. Reliable and effective finite element procedures are discussed with their applications to the solution of general problems in solid, structural, and fluid mechanics, heat and mass transfer, and fluid-structure interactions. The governing continuum mechanics equations, conservation laws, virtual work, and variational principles are used to establish effective finite element discretizations and the stability, accuracy, and convergence are discussed. The homework and the student-selected term project using the general-purpose finite element analysis program ADINA are important parts of the course.

The objective is to teach in a unified manner the fundamentals of finite element analysis of solids, structures and fluids. This includes the theoretical foundations and appropriate use of finite element methods.

This OLogy matching game challenges kids to match pictures of eight ocean creatures with their descriptions. The reward? Eight new OLogy trading cards.

Teaches the fundamentals of engineering operating systems. The following topics are studied in detail: virtual memory, kernel and user mode, system calls, threads, context switches, interrupts, interprocess communication, coordination of concurrent activities, and the interface between software and hardware. Most importantly, the interactions between these concepts are examined. The course is divided into two blocks; the first block introduces one operating system, UNIX® v6, in detail. The second block of lectures covers important operating systems concepts invented after UNIX® v6, which was introduced in 1976.

This Web site, created to complement an American Museum of Natural History exhibition, takes an in-depth look at pearls. It includes the following sections .What Are Pearls? covers how pearls are formed naturally; what causes differences in surface, size, shape, color, overtone, luster, and iridescence; and how imitation pearls are created. Obtaining Pearls looks at the different ways pearls and mother-of-pearl have been gathered throughout history. Freshwater Pearls describes the pearl-forming mollusks that live in lakes, rivers, and streams, and the gems they create. Marine Pearls looks at marine mollusks, the best-known sources of pearls, and how each species has a unique form, ecology, and history. Pearls in Human History examines how pearls became important symbols of wealth, status, and religious beliefs, as well as how mother-of-pearl shells had an even higher value for some cultures. Gallery includes a multimedia presentation on the evolution of mollusks and annotated photographs of everything from a giant clam shell to Marilyn Monroe's necklace.
