Buffalo Flyover: April 12, 1998
Zoom onto metropolitan centers from wide angle views, 11 seconds each.
Pan and Zoom toward Earth
Using data from different spacecraft and some powerful computer technology, visualizers at the Goddard Space Flight Center present you with a collection of American cities in a way you have never seen them before. Starting with our camera high above the Earth, we rush in towards the surface at what would be an impossible speed for any known vehicle. Passing though layers of atmosphere, the colors of our destinations shimmer with their own unique characteristics, and suddenly we find ourselves fl

NDVI for the United States as of May, 2002
New satellite-derived images of vegetation confirm extremely dry conditions exist that are ripe for fires in the western United States, according to a data collaboration between NASA and the USDA Foreign Agricultural Service.

Food Vocabulary (Irish) Quiz 4
The pupil will revise the theme of Food. Written questions will be used to assess the understanding of the pupil. The pupil will be able to correct themselves. The pupil will use interactive resources to encourage reading.
NeuroLogic Exam: Introduction: "x" Values
So far we have a handle on the vertical localization within the neuroaxis but we have a very flat, one-dimensional structure. We need to have a way to come up with "x" values. Let's rotate the neuroaxis by 90 degrees so we can see it in the coronal plane. Now we can appreciate that most structures in the neuroaxis have a right, left or midline orientation on our "x" axis. The first principle of neurologic diagnosis is regional or anatomical localization. In order to become skillful the student m
This lesson is an exciting conclusion to the airplanes unit that encourages students to think creatively. After a review of the concepts learned, students will design their own flying machine based on their knowledge of the forces involved in flight, the properties of available materials, and the ways in which their flying machine could benefit society. Students will also learn how the brainstorming process helps in creative thinking and inventing and that scientists and engineers use this techn
Sea stars live in low tide areas and eat both plants and animals. On the underside of sea stars' arms are tube feet which use water and muscular forces to suction to rocks, move, and capture prey.
Sea Lion Skeleton - Skull
The carnivorous sea lion uses its sharp pointed teeth and large mouth to shred and tear its prey. The large nose and large eyes on either side of the skull help the sea lion to detect prey. The skull protects the brain from damage and injury.
The Remarkable Cocklebur: Worldwide Hitchhiker and Nature's Velcro
This essay from Wayne's Word explores the hitchhiking method of seed dispersal, and how a closer look at one of these bur plants gave rise to an invention.
Serial Dilution of Food Coloring Dye
Students use dyes to explore serial dilution, an important technique in physical science and engineering. Students systematically dilute solutions of food coloring with pure water. They observe how the color intensity, or saturation, of each subsequent solution changes. They also keep a running calculation of the concentration of drops per ml water. They apply what they learn to discussions of biomedical engineers working with cells.
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
Making Decisions: Packaging and the Environment
This activity has students redesign and justify the packaging currently used in some consumer products. Design criteria include reducing the amount of packaging material by 25%.
Floaters and Sinkers: Curricular Unit
This curricular unit introduces students to the important concept of density. The focus is on the more easily understood densities of solids, but students can also explore the densities of liquids and gases. Students devise methods to determine the densities of solid objects, including the method of water displacement to determine volumes of irregularly-shaped objects. By comparing densities of various solids to the density of water, and by considering the behavior of different solids when place
To learn how friction affects motion, students explore how different textures provide varying amounts of friction to objects moving across them. They build a tool to measure the amount of friction between a note card and various surfaces by measuring the distance that a rubber band stretches. They experiment with a range of materials to determine which provides the least/most friction.
