Transistors are the building blocks of modern electronic devices. Your cell phones, iPods, and computers all depend on them to operate. Thanks to today's microfabrication technology, transistors can be made very tiny and be massively produced. You are probably using billions of them while working with this activity now--as of 2006, a dual-core Intel microprocessor contains 1.7 billion transistors. The field effect transistor is the most common type of transistor. So we will focus on it in this activity.

All cells, organs and tissues of a living organism are built of molecules. Some of them are small, made from only a few atoms. There is, however, a special class of molecules that make up and play critical roles in living cells. These molecules can consist of many thousands to millions of atoms. They are referred to as macromolecules (or large biomolecules).

This activity is for an introductory oceanography course. It is designed to allow students to use various tools (satellite images, Google Earth) to explore the shape of the sea floor and ocean basins in order to gain a better understanding of both the processes that form ocean basins, as well as how the shape of ocean basins influences physical and biological processes.

Video clips from federal and regional agencies show scientists at work with tools used to collect data about the climate and weather. This article, from the free, online magazine Beyond Weather and the Water Cycle, will help students visualize the tools and how they are used in the atmosphere, at sea, and other hard-to-access locations.
Investigate the effect of gravity on objects of various mass during free …
Investigate the effect of gravity on objects of various mass during free fall. Predict what the position-time and velocity-time graphs will look like. Compare graphs for light and heavy objects. Was Galileo Right is the last of five SmartGraphs activities designed for a typical physical science unit of study on the motion of objects.

Writing a Wikipedia article about a genetic disease is a good culminating activity for a genetics course or module, as it requires synthesizing and interpreting a wide range of genetic information. This assignment also includes a potential service component, which is normally very difficult in genetics.
