The American Society of Mammalogists
Founded in 1919, the American Society of Mammalogists (AMS) is an organization, composed primarily of professional scientists, that promotes mammal study. The members of AMS also work to provide "information for public policy, resources management, conservation, and education." A notable ASM site feature is the Mammal Image Library which provides "images of mammals for educational purposes worldwide." The ASM website also contains information about two main publications, _The Journal of Mammalog
Ozone in the atmosphere : ozone depletion
What processes cause a depletion of the ozone layer? This informational page, part of an interactive laboratory series for grades 8-12, explores natural and human-made destruction of the ozone layer. Here students read about the instability of ozone atoms and the naturally changing quantities of ozone in the air. Volcanoes, the oceans, and other natural processes provide chemicals that break down ozone. Chemical equations of the breakdowns are provided. A discussion of the use of chlorofluorocar
Thinking involving very large and very small quantities
Intuitively a million is a lot more like a billion than ten is like one hundred, because our intuition has some grasp of ten and one hundred, but we have little grasp of what millions and billions involve. Fortunately, there is often a way to make intelligent decisions involving big quantities. Use arithmetic! Typically we don't need more than multiplication and division to put things into terms we can deal with. If we are unwilling or unable to do the calculations, we should at least recog
A Mathematics Fantasy: The Million $ Mission
This math site has students study exponential growth. Students are provided with two payment options, one cent on the first day, two cents on the second day, and double their salary every day after that for the thirty days, or they can choose exactly one million dollars. Included are two versions, a one page version that has the calculations worked out and a multi-page version that is appropriate for printing so students can use their own calculations. An exponential growth graph, a formula to f
How do you light up your bike without reflectors or lamps?
Bicycle safety is a critical matter. This riddle asks students how they can illuminate their bicycles without using reflectors or headlamps. Before they select their answer, students are given a clue. They read about and watch a video clip of two children's attempts to use glow-in-the-dark materials to light up their bikes. The riddle's final page presents students with three clickable answer choices. Brief feedback is given for the incorrect choices. When students select the best answer, a shor
The Michelson-Morley experiment
This lecture is also available in French and Spanish, and in PDF. A flashlet simulation of the experiment is included. It describes in comprehensible detail this historical experiment which showed that light has wave properties, but no aether exists, thought to be the medium of the waves.
This two-minute radio program features sound clips of infant and adult storks together with a commentary on these two distinct animal sounds. An environmental official from Hungary, where the majority of white storks live during the spring and summer, describes the function of the noises made by chicks and adult storks. He also discusses the instincts exhibited by adult pairs when they are raising baby storks. The archived program, part of the Pulse of the Planet radio show, is available here in
Mortality rate of captive-bred and released carnivores is 70%
This January 25, 2008 entry in the NSDL Expert Voices blog Connecting News with National Science Education Standards deals with survival rates of captive-bred carnivore released into the wild. It points to modifications breeders should make to decrease mortality rates. Additional links to teaching resources related to populations, ecosystems, and diversity are provided
Arctic Region Map
This map shows a political view of the Arctic region as defined by the area where the highest temperature for the warmest month is below 10 degrees C.
Science Sampler : Growth Potential
Students will enjoy carrying out this exciting and challenging research project that combines science with computers and mathematics to investigate how polyacrylate animals change in size over time when placed in water and aqueous salt solutions. The hands-on activity motivates students and provides them with enjoyable and rewarding science project experiences. Here they have an opportunity to solve a problem and use the science inquiry skills of observing, collecting, organizing, and analyzing
Examine global surface currents
This Earth science animation is designed to help high school students visualize the causal relationship between global winds and the temperature and direction of ocean surface currents. The animation presents a world map that shows the direction of surface currents, which are color-coded to indicate warm and cool temperatures. Moving the cursor over the map superimposes gold arrows that indicate wind direction. The introduction summarizes the relationship and calls students attention to the temp
A Maths Dictionary For Kids
An animated, interactive dictionary for students which explains over 400 common mathematical terms in simple language. Includes definitions, animated examples, interactive activities, practice and lots of different calculators.
Celestial navigation is the process of finding your position on Earth based on astronomical guideposts. In this lesson, explore the principles of navigation; build tools to observe celestial bodies, and learn how science, mathematics, technology, and history are intertwined.
Statistics and probability. Grades 6-8
This MathPARTNERS unit contains seven lessons with hands-on learning activities for exploring statistics and probability with students in grades 6-8. The lessons, designed for mentoring situations, may also be helpful for teachers and parents. Each lesson with reproducible student materials, features an overview of the mathematics, preparation guidelines, teaching tips, and suggestions for how to use each activity to develop specific mathematics concepts. Statistics activities focus on posing qu
This web page focuses on watersheds, the topic of one of the books in the curriculum series that the larger web site accompanies. The page mentions why it can be beneficial for students to investigate local watersheds. The term watershed is defined, and examples of different sizes of watersheds are given. In addition, the page explains why local governments often manage watersheds. Links are provided to water quality experiments, to related online materials on other sites, and to information abo
New York Times Daily Lesson Plan: Mathematics
These lesson ideas from the New York Times offer suggestions for ways to draw on real world issues and statistics to develop lessons in mathematics. For example, in one lesson students convert statistics about gun injuries into visual presentations, then use these as the basis for a poster campaign to teach children about the dangers of guns in home while another lesson idea involves designing brochures that are intended to explain specific mathematical concepts to a popular audience. Each lesso
Decarteret matches pole vault record at Florida State
The Northeastern women's track & field team recorded 15 top-10 marks, including another record-breaking performance by Jillena Decarteret, amidst stiff competition at this weekend's Florida State Relays in Tallahassee, Fla. Decarteret tied the school record in the pole vault with a winning performance of 4.06m (13'3.75), beating out 20 others for the title. The sophomore's vault matched Laura Chmielewski's mark set back almost seven years ago on May 8, 2004. Decarteret has continued to make upw

A Few Minutes with Nolan Bushnell - Creator of Pong and Atari I had the fortunate experience of sitting down and having an hour-long conversation with Nolan Bushnell, inventor of PONG and ATARI, for an upcoming project I am working on. That video won't be released for a few months, but he did offer to chat with me for an extra five minutes for Tech with Tina.
