Additional Resources:

The World of Microscopy

An incredibly complete site (from Florida State Univ.) complete with special sections on the optics and history of the microscope, and even a series of web-operated virtual microscopes. Be sure not to miss the Virtual SEM - a Scanning Electron Microscope you can "operate" over the web!)

NATURE retracts a report on transgenic corn
A recent (2002) example of a major scientific journal acknowledging an apparent mistake in one of its research reports.

Chapter 1
The Science of Biology

Section 1-1: What Is Science?
The goal of science is to investigate and understand nature, to explain events in nature, and to use those explanations to make useful predictions.

Section 1-2: How Scientists Work
Whenever possible, a hypothesis should be tested by an experiment in which only one variable is changed at a time. All the other variables should be kept unchanged, or controlled.
In science, the word theory applies to a well-tested explanation that unifies a broad range of observations.

Section 1-3: Studying Life
Living things share characteristics including cellular organization, reproduction, a universal genetic code, growth and development, use of materials and energy, response to their environment, and maintaining an internal stability.
Living organisms can be studied at different levels of organization, from the molecular level to the biosphere.

Section 1-4: Tools and Procedures
Most scientists use the metric system when collecting data and doing experiments.
Light microscopes produce images by focusing visible light rays. Electron microscopes produce images by focusing beams of electrons.
