Mining Minerals and Metals
In this video from the Science and Technology Chat series, elementary school students visit the McCaw School of Mines and take a tour of a demonstration mine. First, they learn how gold is extracted from sediment through panning. They also learn about structural safety features and the use of controlled explosions. Finally, they learn that Nevada mines contain large deposits of gypsum, which is used in many everyday items, including drywall. Run time 02:45.
In this video, a classroom teacher defines possessive nouns and tells how to make nouns possessive. Then, she provides different examples of possessive nouns in different classroom situations. Different slides of students are shown illustrating each sentence that uses a possessive noun.
When to Use Capital Letters
When to Use Capital Letters. Part of the series: Teaching & Writing. Capital letters are used for proper nouns, for the pronoun "I," for the beginning of first and last names, for titles, in acronyms and at the beginning of each new sentence.
Capitalization of Languages and Nationalities
In this video, a teacher gives a brief overview of rules surrounding the capitalization of languages and nationalities, then gives examples of sentences written incorrectly that must be fixed.
Nanna Know It All Explains Buoyancy
Nanna explains the buoyancy of ocean guiding vessel. She uses raisins and soda water to demonstrate. The Kids Know It movies bring your student on a fun and interactive journey through the world around us. Run time 05:52
This 1:30 video is about atoms in their ground state that are electrically neutral and have an equal number of electrons and protons. It uses graphics and a narrator. A good introduction.
Molecules in Liquid
As molecules in a solid get hotter, they vibrate faster and faster and eventually slip out of their lattice-work pattern. When this occurs, the substance melts, changing from a solid to a liquid state. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level.
Forces in Nature: Landslides
A three minute video explaining landslides and shows specific examples of landslides in the bay area.
Soil Texture - Environmental Science
Learn all about soil texture and how to test for clay, silt and sand. English captions are at the bottom of the screen. The words are small so the viewer may want to open the video to 'full screen'. Key vocabulary words include: sand, silt, clay, organic matter, porosity, permeability, and loam. Run time 02:22.
Volcanoes from Around the World
This video shows photographs of volcanoes from around the world. It is set to music and each photo gives the location of the volcano. It shows both dormant and erupting volcanoes. Music may be a bit distracting to the viewer. (06:07)
Volcanic Eruption Song
A song about what happens when volcanos erupt: pressure builds up constantly until an explosion occurs. This is an animated video.
The Ring of Fire, Part 1
The Pacific Ring of Fire (or sometimes just the Ring of Fire) is an area where large numbers of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. (10:34)
Dating Lava Flows on Mauna Loa Volcano, Hawaii
For hundreds of thousands of years, lava flows have created intricate patterns on the slopes of Hawaiʻi's Mauna Loa volcano. Until the mid-1970s, it was impossible to know when each of the flows occurred. However, as this video segment adapted from NOVA describes, scientists are now using tiny artifacts of life encased in hardened lava flows to piece together the mountain's complex geological and biological history. Closed captioning included. Run time 04:36.
Mount Pinatubo: The Aftermath of a Volcanic Eruption
The eruption of Mount Pinatubo in 1991 was the largest volcanic eruption in 80 years. The explosive eruption deposited tons of ash on the towns and villages near the volcano's base. Even more devastating than the eruption, however, were the devastating flows of water and debris that resulted when monsoon rains mixed with the accumulated volcanic ash. This video segment adapted from NOVA depicts some of the impact of these events on the communities surrounding the volcano. Closed captioning.
Extreme Oil Drilling
The experts in this video discuss the difficulty in finding new locations to dig for oil. In order to get oil flowing freely in the cold tundra, hot steam is pumped into the ground using massive amounts of energy.(03:04)
The Story of Petroleum
We use oil in our daily lives and know that it is a thick substance buried thousands of feet underneath the Earth. But how did it get there? How do we get it out? What do we do with it? and Why is it so important? This is an educational video which introduces and explains the processes involved in oil exploration, drilling and refining. Video footage was filmed on location in the Illinois Basin with scenes from a geologists office, drilling rig, pumping unit, tank battery, refinery, and mo
Alternative Energy - Biofuel from Algae
"Algae is the fastest growing plant life, and as an organism it converts sunlight into oil, scientists theorize that Algal biofuel can produce a whopping 30 times more energy per acre than any other biofuel option." (02:01)
Advantages & Disadvantages of Wind Power
Wind power is a form of renewable energy. It's a domestic source of energy, reliable, and quiet. Some disadvantages of wind power include high expense, poor aesthetics, harmful to birds, and storage concerns. This video is in lecture format with an instructor standing in front of a white board. (03:38)
Ocean Odyssey - Surface Currents
This is a segment from the Ocean Odyssey series that describes in layman's terms what surface currents are, what role they have in the creation of climate, and how they form. Produced for students and is suitable for elementary and older.
(This is an Emmy award-winning series of instructional programs that introduces students in grades 3-5 to NASA and integrates mathematics, science, and technology through the use of Problem-Based Learning (PBL), scientific inquiry, and the scientific
What Causes Waves?
The major cause of waves, specifically ocean waves, is wind,
although waves can also be created by tides and earthquakes. Learn
how waves are simply the result of winds passing over water.
