Created by the Concord Consortium, the Molecular Workbench is "a modeling tool for designing and conducting computational experiments across science." First-time visitors can check out one of the Featured Simulations to get started. The homepage contains a number of curriculum modules which deal with chemical bonding, semiconductors, and diffusion. Visitors can learn how to create their own simulations via the online manual, which is available here as well. The Articles area is quite helpful, as it contains full-text pieces on nanoscience education, quantum chemistry, and a primer on how transistors work. A good way to look over all of the offerings here is to click on the Showcase area. Here visitors can view the Featured simulations, or look through one of five topical sections, which include Biotech and Nanotechnology. Visitors will need to install the free Molecular Workbench software, which is available for Windows, Linux, and Mac.

This video from Nature features the start of the monarch butterflyŒë_í_Œ_ northward trek.

This assignment uses a computer simulation of fruit fly genetics to have students design and interpret monohybrid crosses of a trait with simple dominant and recessive alleles. Detailed instructions with animated examples, background material, a sample report and a rubric are included.

This video segment follows neurophysiologist Allen Counter as he studies an epidemic of hearing loss in Moriussaq, Greenland, one of the quietest places on Earth. Footage from NOVA: "Mystery of the Senses: Hearing."

This article describes the work of Hubert Staudigel and Cathy Constable, researchers from Scripps Institution of Oceanography who study Mt. Erebus, Antarctica's most active volcano.

This activity is a longer project that involves using inquiry to find out what kinds of aquatic animals live in our school pond. Students use direct observation, journaling, outdoor classroom techniques, research skills, collaboration, and service learning to learn about their question.

An informative site that touches on evolution, life cycle and interesting facts about sharks.

Students learn about frequency and period, particularly natural frequency using springs. They learn that the natural frequency of a system depends on two things: the stiffness and mass of the system. Students see how the natural frequency of a structure plays a big role in the building surviving an earthquake or high winds.

This activity uses a cultural story to excite kinesthetic homework, nature journaling and daily adventure in a child's own back yard or kitchen flower pot.

This activity allows students to figure out how they can negatively impact wildlife without trying.

In this Interactive Lecture Demonstration, students will attempt to predict the content of articles on the Health Science pages of French newspapers by reading headlines. They then read the actual articles and reflect on the actual content of the news articles.

Coral reefs are often portrayed as brightly lit, bustling underwater marvels full of colorful creatures. This video segment, adapted from NOVA, paints a different picture as it explores the nocturnal behavior of organisms in the reef.

This video segment adapted from the NOW-RAMP 2002 Expedition documents a research expedition to Nihoa Island. It showcases Nihoa's unique birds and plants, the threat posed by invading grasshoppers, and restoration efforts.

Nitrogen, one of the most abundant elements in the universe, is essential to life. This interactive activity adapted from the University of Alberta provides an overview of the nitrogen cycle.

This article profiles Gerrit Vyn and Martha Fischer, sound recordists with the Macaulay Library, Cornell University, and their expedition to Nunavut, Canada, to record male sanderling vocalizations.

In this lesson designed to enhance literacy skills, students examine the nutritional content of different foods and learn about the health benefits and risks associated with the food choices they make.

A one page activity that takes students to several websites related to the obesity epidemic. First they can calculate BMI, then learn about national trends in the rate of obesity and finally use a tutorial on insulin and diabetes.

This is a classroom activity in which students observe and describe cells in stages of division. They share observations about what they see in the cells, then formulate questions and do research concerning the changes that take place in cells during the process.
