Learners observe crystals under the microscope. In this science instructional activity, students compare how the crystal look like using their eyes, hand lens and microscope. They identify the type of crystal based on the amount of light...

Eighth graders differentiate speed and velocity. For this physics lesson, 8th graders explain Newton's laws of motion. They calculate speed using a mathematical formula.

Students construct an evolutionary tree representing specialization, diversity, and selection using easily obtained materials. They use at least twenty pieces of hardware to classify then develop "evolutionary" relationships between the...

By the end of this section, you will be able to explain how the methods of science are used to make scientific discoveries; define a scientific model and describe examples of physical and mathematical models used in physics; and compare...

This lesson introduces the concept of a scientific principle, and explains their importance in science. [1 min, 49 secs]

The National Institute on Drug Abuse created a guide on the principles of drug addiction treatment. That guide is available here online. It's meant to help individuals answer questions such as finding the most effective methods of...

In this lab, students will use the scientific method to design an experiment that explains how/why a submarine floats and sinks.

An essay by Frederick W. Taylor that outlined his theory of scientific business management, how it worked, and why it was important to industry in the beginning of the 20th century.

This tutorial site provides links to articles about writing a scientific report or essay as well as to sample essays.

This lesson introduces the concept of a principle and explains what they represent. It is 4 of 4 in the series titled "Principle."

Explains the Heisenberg Uncertainty Principle, that it is impossible to know both the momentum and position of an electron, along with describing the impact that it made upon the scientific community upon its introduction in 1927.

Power Point presentation on scientific method for NAS 102 Human and Environmental Biology II.

Good biography of Frederick Taylor, author of "The Principles of Scientific Management." Includes links to other sites and great pictures.

Students observe Archimedes' principle in action in this challenge where a toy boat is placed in a container of water and a rock is placed on the floating boat. Students must explain why the water level rises/falls/stays the same based...

This comprehensive study guide covers the main terms and concepts needed for an earth science unit on the scientific principles of correlation and causation. Review questions are included at the bottom of the study guide.

This site from Fordham University is an exerpt from Newton's famous "Principia."

Investigate and demonstrate principles of flight with the Flying Tim Bird. Draw a hypothetical model of the mechanism inside the toy bird that makes the wings flap, then experiment with and videotape its flight to explain how lift works...
