A great reference for information on neon. This is as thorough of a site as you are likely to find.

An incredibly thorough site with a wealth of basic information on oxygen. Highly recommended.

An oustanding source of information for all sorts of general information on palladium.

Excellent source of information on phosphorus including its physical and chemical properties. Highly recommended.

As the name of this site implies, this is a huge reference site for elemental information. Whether you are looking for properties or isotopes, this site probably has what you need. Images of structure and electron energy level can be found here, as well as links to related materials.

Excellent resource for just about anything you could ever want to know about selenium.

Describes how a geyser works and provides a nice diagram of the geological structure of a geyser.

This tutorial looks at the anatomy of the eye and how the sense of sight works. This is the first part of a learning module. Subsequent sections cover how images are formed and detected, the concept of accommodation where the eye adjusts its focus, and how farsightedness and nearsightedness are corrected. Includes detailed calculations using physics formulas, e.g., to find the quantitative relationship between the object distance, image distance, and focal length.

At this resource learners can take a look at the plant kingdom with a detailed examination of fossil records, life history and ecology, systematics, and morphology.

This video segment adapted from A Science Odyssey uses animation and archival footage to provide an overview of the theory of plate tectonics.

This video segment adapted from NOVA uses animation to show the relationship between the movement of a tectonic plate and whether volcanoes on the Hawaiian Islands are active or dormant.

Many simple forms, such as cinquain and haiku, that follow set formats, are included in this poetry lesson plan.

Student teams investigate biomedical engineering and the technology of prosthetics. Students create a model prosthetic lower leg using various materials. Each team demonstrate its prosthesis' strength and consider its pros and cons, giving insight into the characteristics and materials biomedical engineers consider in designing artificial limbs.

In this scrollable interactive, the four levels of protein folding are explored in detail by exploring the structure of hemoglobin.
