The U.S. invades Kwajalein on January 31, 1944, breaking the outer ring of the Japanese Pacific territory. Japanese forces are poorly trained and are easily outnumbered by American troops. After four days nearly all of the Japenese troops are wiped out and Allies claim victory on February 3, 1944. In this video clip, learn more about swift Battle of Kwajalein. (2:04)

Students learn the following theorems related to tangents. If a line is tangent to a circle, then the line is perpendicular to the radius at the point of tangency. If a line is perpendicular to a radius at its outer endpoint, then the line is tangent to the circle. If two tangent segments are drawn to a circle from an external point, then the tangent segments are congruent. Students are then asked to use these theorems to find missing segment lengths and missing angle measures in given figures. Students also learn the definitions of common internal tangents and common external tangents. (03:07)

The auditory center, in the brain, shown above in red, is concerned with hearing. Although shown here on the outer surface of the brain, most of this area lies within the temporal lobes and is found within the surface of the cerebral cortex on both sides of the brain. (00:59)

The world owes much of its cultural legacy to Constantinople’s walls. When Constantinople was under siege by neighboring enemies, the Roman city’s elaborate system of moats, outer walls, and inner walls stood tall. Surviving numerous fire attacks, the walls were eventually brought down by more modern tools of warfare, but, thankfully, classical culture survived. (04:17)

(00:23) 3-D video from NASA's Chandra X-Ray Observatory. It shows the explosion of SN 2006gy. he extremely massive star shed some of its outer layers in a large eruption prior to its violent collapse. The explosion then plows into the expelled cooler gas, creating a brilliant light show. Astronomers think Eta Carinae in the Milky Way could explode in the same way at any time.

This short video gives excellent real life footage of a Horse's Hoof Clam. Students will enjoy listening to the ocean sounds as they watch the close up views of this amazing invertebrate. A member of the giant clam family (Tridacnidae), the horse’s hoof clam (Hippopus hippopus) is named for the shape of its shell. Reddish bands on the outer side of the shell give it its alternative common name of ‘strawberry clam’.As in all clams, the body of the horse’s hoof clam is enclosed within a shell made from two separate hinged sections, known as valves. This is a great resource to help build background knowledge and to help make real world connections between nature and the classroom. (0:27)

Students will enjoy listening to the ocean sounds as they see the close up views of a Common Cockle feeding through a siphon. This well-known edible cockle has a solid shell, consisting of two valves, which feature prominent ribs and concentric growth-lines. The outer surface of the shell is off-white, yellowish or brown, and the inner surface is white. This is a great resource to help build background knowledge and to help make real world connections between nature and the classroom. (0:25)

This short video gives excellent real life footage of a Common Jellyfish. Students will enjoy listening to the ocean sounds and seeing the close up views of these amazing creatures. As its name suggests, the common jellyfish (Aurelia aurita) is the most common jellyfish species on British shores. The body is a saucer shaped 'bell', which is colorless except for four obvious violet gonads visible in the center of the disc. The outer edges are fringed with many small tentacles, and four stocky 'arms' surround the mouth. This is a great resource to help build background knowledge and to help make real world connections between nature and the classroom. (0:34)

The earth is made up of four layers – the inner core, outer core, mantle and crust. The mantle and crust are a thin skin compared to the other layers. The mantle is about 1,800 miles thick, while the crust is only about 8 miles thick. This thin skin is broken into pieces called tectonic plates. The plates are like puzzle pieces, floating on top of the Earth’s inner core. Sometimes the pieces slide under or against each other and become stuck.When the pieces slide apart, they create tremendous force. This force causes the earth to shake and ripple. (08:02)

Should be done by a teacher in a classroom, not at home. Put a burning piece of a paper or other flammable material into a bottle with a neck slightly narrower than an egg. Burning paper will warm up and expand the...expand the air in the bottle and molecules of air will leak out of the bottle. Put an egg -- boiled and peeled, on the neck of the bottle. When the fire goes out, the air in the bottle cools down. Atmospheric pressure in the bottle decreases. As a result of different atmospheric pressures, higher outer pressure pushes the egg into the bottle. (02:21)

Our planet Earth is divided up into four layers: the inner core, outer core, mantle and crust. The solid inner core is made up of blazing hot iron and nickel, and is surrounded by the liquid outer core. The mantle is made up mostly of magma, or molten rock, and the crust is the layer we live and walk on. The crust is also made up of Earth's tectonic plates, which move constantly over the mantle, and occasionally collide. This is how earthquakes and volcanoes occur. (03:24)

Today we're going to tell the story of a quiet revolution in the 1960s that shifted our entire understanding of how the Earth works. We currently believe that the Earth's broken outer shell rises from the mantle and folds back in - kind of like a dance of creative destruction and reconstruction - giving us our continents and oceans, mountains and valleys, volcanoes, and earthquakes. And, it would take a group of scientists all over the world to get us this grand unifying theory of plate tectonics. (10:58)
