The Garbage Gang spots a dead fish on their fishing trip, and they wonder, Why do dead fish float? Luckily, a live fish helps them out, and soon they're swimming in knowledge about states of matter.

Mixes science and art to bring the world of physics to life, with a gaggle of wacky characters to explain the building blocks of our universe

"Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter embedded in the Milky Way. In a sense, it...

In this video lesson, Paul Andersen explains how living organisms exchange matter with the environment. The importance of the surface area to volume ratio is emphasized using a simple mathematical model. The essential components for life (water, carbon, nitrogen and phosphorus) are described. Each of these is are vital to the four major macromolecules. A brief description of the biogeochemical cycles is also included.--Publisher.

"If existing models of the structure of the universe are correct, then 85 percent of the cosmos comprises a substance called dark matter. Yet no direct evidence of dark matter exists. Award-winning science journalist Govert Schilling details the quest to detect dark matter and how the search has helped us to understand the universe we inhabit"--

"Explains how to use the scientific method to conduct several science experiments about the properties of matter. Includes ideas for science fair projects"--Provided by publisher
