Images of Earth and Space: SC99 Edition
From our home planet to distant neutron stars, this narrated videotape presents recent scientific visualizations of observation and simulation data. We begin with a dramatic journey over SC99 host city Portland and its surroundings. Later explorations accompany the X-33 aerospace plane on its first test flight, witness Mississippi River flooding, and follow global life over 22 months. New views of Mars reveal a basin that could swallow Mount Everest, while a simulation tests how rovers would nav
Pesticides and fertilizers can run off of cropland and into bodies of water. The water sources can become contaminated in this way and harm organisms that live in the water, as well as any organisms that use it as a water source.
How Many Drops?
In this lesson and its associated activity, students conduct a simple test to determine how many drops of each of three liquids can be placed on a penny before spilling over. The three liquids are water, rubbing alcohol, and vegetable oil; because of their different surface tensions, more water can be piled on top of a penny than either of the other two liquids. However, this is not the main point of the activity. Instead, students are asked to come up with an explanation for their observations
Atoms: Protons, Neutrons, and Electrons - by StudyJams
An atom is a tiny particle in matter, and atoms are made of protons, neutrons, and electrons. Some matter, like your body or your book, is made of lots of different kinds of atoms, but elements are made up of only one kind of atom. Learn more about atoms with this cartoon animation from StudyJams. A short, self-checking quiz is also included with this link.

Building Roller Coasters
Students build their own roller coasters using pipe insulation and marbles, and then analyze them using principles of physics. They examine conversions between kinetic and potential energy and frictional effects to design roller coasters that are completely driven by gravity. A class competition is then held to determine the most innovative and successful roller coasters.
Dolphin Skeleton - Limb (flippers)
The flippers of the dolphin help it swim through water. The ball and socket joint at the shoulder help the dolphin steer and roll while in the water, allowing it to actively swim and catch food while avoiding its predators.
