This interactive timeline provides information on the big bang as well as other major events of universe evolution. It also provides predictions about the universe's future.

A study of the moon that centers on its origin, its structure, and its behavior.

The purpose of this lesson is to teach students about the three dimensional Cartesian coordinate system. It is important for structural engineers to be confident graphing in 3D in order to be able to describe locations in space to fellow engineers.

This video segment adapted from NOVA explains the origin of the elements and how scientists use unique element profiles to identify supernova types.

This video segment adapted from NOVA follows the Apollo 15 astronauts as they collect samples of ancient rock from the Moon's crust, whose discovery helps lead to a radical new theory about the Moon's origin.

This video segment [3:56] adapted from NOVA follows the Apollo 15 astronauts as they collect samples of ancient rock from the Moon's crust, whose discovery helps lead to a radical new theory about the Moon's origin.

Students are introduced to the coordinate plane and use it to represent the location of objects in space, as well as to represent patterns and real-world situations.

Detailed math tutorial features notes and examples that take a look at symmetry, discussing symmetry about the x-axis, y-axis, and the origin. Shows methods for testing the symmetry of a graph.

Beginning with an image termed the "Brief History of the Universe" this site examines (briefly, as noted) a timeline of the universe as dictated by the image. The timeline includes information on the big bang theory, the dark ages, the first light, and today.

Use real-world data to make a visual display using scatter plots.

A free CK-12 account is required to view all materials.

All it takes is a simple S to make most English words plural. But it hasn't always worked that way (and there are, of course, exceptions). John McWhorter looks back to the good old days when English was newly split from German -- and books, names and eggs were beek, namen and eggru! [4:26]

Did you know that gold is extraterrestrial? Instead of arising from our planet's rocky crust, it was actually cooked up in space and is present on Earth because of cataclysmic stellar explosions called supernovae. CERN Scientist David Lunney outlines the incredible journey of gold from space to Earth. [4:34]

Compare the printed page to an electronic web page and use this activity to discuss the similarities and differences. A cross-curricular tie-in with ecosystems. Could easily be adapted to another subject area.

A detailed examination of "what is known about the Big Bang itself, the age of the universe, and the synthesis of the first atoms."

In this video from the Science and Technology Chat series, learn about astrobiology, an interdisciplinary field that uses biology, astronomy, and geology to study the origins of life on Earth and to search for possible life on other planets. [1:37]
