InterMath is a professional development effort designed to support teachers in becoming better mathematics educators. It focuses on building teachers' mathematical content knowledge through mathematical investigations that are supported by technology. InterMath includes a workshop component and materials to support instructors. For each of the following problems, consider how you would pose the same problem to your students. Would the wording need to change? Would you need to include more pictur
An interactive applet and associated web page that demonstrate equiangular triangles (all interior angles congruent). The applet presents an equiangular triangle where the user can drag any vertex. As the vertex is dragged, the others move automatically to keep the triangle equiangular. The angles and side lengths are updated continuously to show that the all interior angles are always congruent. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a co

Absent the rule of law, many in the north Caucasus region are embracing fundamentalist Islam to foster some sense of stability
"Ithaka" by C P Cavafy (poetry reading)
This about the Odyssey in which Odysseus, aka Ulysses, finds his way back home to Ithika after the Trojan War. The journey takes him ten years. He meets many perils on the way, such as the Laistygonians who were flesh-eating giants. It's a parable of the journey of personal discovery a man must make and the monsters within himself that he must face. You can hear Keeley, the translator, reading it here: http://poemsoutloud.net/audio/archive/keeley_reads_ithaka/ Here's the poem in the origi
Genetics in the Classroom and the Curriculum
In this online article, from the Museum's Musings newsletter for educators, two participants in the Genomics Study Group share their strategies for teaching genetics to high school students. They include tips on: where to begin, including teacher preparation and good content starting points how to use genetics labs when they are available, and alternate approaches when they're not ways to use case studies and topics in the news to increase students' interest guidelines for handling bioethics in
Wake Meandering -- An Analysis of Instantaneous 2d Laser Measurements
The vast majority of wind turbines are today erected in wind farms. As a consequence, wake generated loads are becoming more and more important. We present a new experimental technique to measure the instantaneous wake deficit directly, thus allowing us to quantify the wake meandering as well as the instantaneous wake expansion expressed in a meandering frame of reference. The experimental results are subsequently used in a preliminary verification of the basic conjecture of a wake meandering mo
Aquatic Animal Skeleton - Gliding Joint
Gliding joints for aquatic animals are located in their backbones. This joint allows the animal to be flexible and change the shape of its body.
Attention to Scaling
In this video segment from Cyberchase, the CyberSquad adds a scale to their bar graph to give a more accurate picture of the bug infestation at the Cybrary.
Let Your Ears do the Walking
In the previous lesson, students learned about the issue of by-catching by fisheries and how it affects marine habitats. Dolphins are one of the main species affected by by-catching Dolphins use echolocation to identify the location of objects in the water, but they have difficulty identifying nets, and thus can be caught accidentally. Students will learn how echolocation works, why certain animals use it to determine the size, shape, and distance of objects, and how humans can potentially take

The Ocean's Role in the Climate System
This online article is from the Museum's Seminars on Science, a series of distance-learning courses that allow educators to discuss scientific ideas and classroom applications with AMNH scientists and educators. "The Ocean's Tole in the Climate System" is part of The Ocean System course.
Audio Gallery: Scientists and Social Responsibility
This online audio gallery is from the Museum's Seminars on Science, a series of distance-learning courses designed to help educators meet the new national science standards. Scientists and Social Responsibility, part of the Frontiers in Physical Science seminar, is available in broadband and modem formats and with a printable PDF transcript. The audio discuss some of the social-responsibility issues that scientists are grappling with today.
This fun Web article is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they learn about volcanoes. The article begins by introducing students to Jim Webster, an Earth scientist at the Museum who studies volcanoes and has re-created the conditions for a magma chamber in his lab. In Visit Jim's Lab, students see firsthand how he studies volcanoes, both in the field and in the lab.
Kids' Guide to the Birds of Central Park
An illustrated guide to birds commonly found in Central Park, and an introduction to birding for young naturalists. The guide also includes information on where to go in Central Park to see birds in various habitats: freshwater, woodlands, and open areas.
Remote Sensing Guides: Viewing Data
These guides offer different options for viewing remotely sensed data. They are presented with some specific instructions on how to view data with common and freely available software. Information is also provided to process satellite imagery to make it easier to identify a variety of land cover features. All guides can be viewed online or downloaded in PDF format.
Remote Sensing Guides: Basic
The Remote Sensing guides are designed for people who want to learn how to benefit from remotely sensed imagery without having to learn the nitty-gritty details of how remote sensing works. All guides can be viewed online or downloaded in PDF format. The guides in the Basicset explain and illustrate fundamentalof remote sensing.
