Designing Mathematics or Science Curriculum Programs: A Guide for Using Mathematics and Science Educ
With the publication of the National Science Education Standards and the National Council of Teachers of Mathematics' Curriculum and Evaluation Standards for School Mathematics, a clear set of goals and guidelines for achieving literacy in mathematics and science was established. Designing Mathematics or Science Curriculum Programs has been developed to help state- and district-level education leaders create coherent, multi-year curriculum programs that provide students with opportunities to lea
Why Teach Bioethics?
Adolescents are passionately interested in ethical questions suggesting adolescence may be a critical period for including bioethics in science education. Knowledge arises when the mind interacts with content; an understanding of ethical issues develops as an evolving process around real-life situations. The question is what role should teachers play in the acquisition of this knowledge?
Illuminations, National Council of Teachers of Mathematics Vision for School Mathematics
The National Council of Teachers of Mathematics Illuminations Web site is designed to illuminate the new vision for school mathematics as presented in NCTM s Principles and Standards for School Mathematics. The site provides online esources that will help improve the teaching and learning of mathematics for all students, from pre-school through high school.
Cosmic Evolution - From Big Bang to Humankind
This site features excerpts from Eric Chaisson's book Cosmic Evolution and includes photos, illustrations and movies. The seven sections includes topics like galaxy formation, the birth and death of stars, the origins of life, and the evolution of intelligence. The site includes follow-up activities for teachers to use in the classroom.
Methods and Strategies : Using Models Effectively
Models are crucial to science teaching and learning, yet they can create unforeseen and overlooked challenges for students and teachers. This article guides students through age-appropriate, critical analyses of instructional models.
What is this atmosphere that surrounds the Earth? This instructional tutorial, part of an interactive laboratory series for grades 8-12, introduces students to the structure, effects, and components of the atmosphere. Here students investigate the composition of the atmosphere; effects of temperature, pressure, and ozone; the greenhouse effect; and how Earth compares with other planets. Interactive activities present students with opportunities to explore ideas and answer questions about the atm
University of Iowa : burn oat hulls for economic, environmental benefit
What is an alternative energy source that is available today? This article, part of a series about the future of energy, introduces students to a pilot project of burning oat hulls at the University of Iowa power plant. Students read that the burning of oak hulls instead of coal provides for cleaner air and additional space in landfills. Copyright 2005 Eisenhower National Clearinghouse
Periodic Table Live!
Periodic Table Live!, produced by the Division of Chemical Education at the University of Wisconsin-Madison, allows users to explore a broad range of information about the elements, their reactions, their properties, their structures and their histories. After selecting an element from the periodic table, users can access a myriad of information divided into three sections: Description, Physical, and Atomic. Students can view short videos of many of the elements reactions with air, water, acids,
Ebola infection reported
This article describes cases and outbreaks of Ebola virus. The focus is on how little is known about Ebola and Marberg viruses, especially about how certain people survive those infections. Copyright 2005 Eisenhower National Clearinghouse
How much does the United States depend on fossil fuels? This web page, part of a site on the future of energy, introduces students to fossil fuels as an energy source. Here students read about the uses, benefits, and limitations of fossil fuels. There is also information on how these fuels are distributed geographically and how they affect the U.S. economy through supply and demand. Thought-provoking questions afford students opportunities to reflect on what they've read. Articles about clean co
The beginnings of probability
These pages present, in terms of a fictional story based on true events, the problem that inspired the development of mathematical probability in Renaissance Europe by French mathematicians Pierre de Fermat and Blaise Pascal. Two equally skilled players are interrupted while playing a game of chance for a certain amount of money. Given the score of the game at that point, how should the stakes be divided? Outlined here is, first, the particular solution and then the general solution based on a c
One in Three Amphibian Species at Risk of Extinction
This February 2, 2008 entry in the NSDL Expert Voices blog Connecting News with National Science Education Standards deals with endangered, possibly extinct and evolutionarily unique, unusual amphibian species. Additional links to teaching resources related to extinction and evolution are provided.
Exploring Earth : explore the world of Earth science
This site could be a powerful supplement to textbook-based teaching and learning. By using this site, high school students can visualize and interact with Earth science concepts in an active, engaging manner. If teachers are looking for online resources that promote inquiry- or discovery-based learning, they could draw from the more than 70 investigations on this site. Specific resources could also be used to introduce a topic, to supplement a reading assignment, or to continue student learning
Donald in Mathmagic Land part 1 of 3 In this popular educational cartoon from Disney (1959), Donald learns about Pythagoras, geometical shapes such as the golden rectangle and the pentagram, and more.

Energy Intelligence Agency
An active way for students to find a few critical facts about how we use energy and how much energy we use. Each student has a “clue”, some of which are pertinent energy facts and others are silly statements that are clearly not related. The students ask each other for clues and mingle until they have collected all the facts they need. This provides a more interactive way to communicate energy statistics without a lecture and introduction with board work. The goal is to introduce students to
Cooking with the Sun
Students learn about using renewable energy from the Sun for heating and cooking as they build and compare the performance of four solar cooker designs. They explore the concepts of insulation, reflection, absorption, conduction and convection.
