How Does the Earth Change? Part 2
This brief video is only one minute and fifteen seconds, but in this short time, the narrator discusses volcanoes and earthquakes.
How Does the Earth Change? Part 1
In this brief video, the narrator discusses weathering and erosion.
Stashing Carbon Dioxide in Basalt Rocks
Basalt formations off the East Coast of the U.S. could suck up a billion tons of carbon dioxide, according to a new study. Paleontologist Paul Olsen, of Columbia University's Lamont-Doherty Earth Observatory, explains how to get the CO2 into the rocks, and why scientists believe it won't leak out.
Vinny Pukh (Winnie-the-Pooh), Part I
Simple but amusing and well-done Russian cartoon of the famous E. E. Milne story, Winnie-the-Pooh. (This episode is Chapter 1.) This cartoon is very famous in Russia. With subtitles.(10:00)
Possessive Nouns For Early Elementary Students
A slow paced power point presentation good for lower elementary students explaining possessive nouns. A possessive noun indicates the nouns is showing ownership. Examples are shown using images of students in a classroom to show possession.
Energy from the Sun
With some very simple equipment and knowledge of basic math it is possible to estimate the power output of the sun. This video describes the process and explains the calculations. The video leaves a challenge: use the results to calculate the total energy arriving at the earth each second and using E=mc^2, calculate the mass loss of the sun. Do NOT look directly at the Sun. (10:27)
How Wind Power is Converted into Useful Electrical Energy
This video provides a brief tutorial - about harnessing wind energy. The high quality animation is supplemented with text - which explains how wind power - is converted to electrical energy, via a generator. Computer animation set to music with labels provided on screen. (No narration) Run time 02:10.
What Is a Wind Energy System?
A wind energy system is a renewable energy system that turns wind energy into rotational energy and mechanical energy. Find out how windmills can power a generator with help from a science teacher. (03:00)
The Giant Redwood Trees of the Pacific Northwest
Science writer Richard Preston (author of The Hot Zone) talks about some of the most enormous living beings on the planet, the giant trees of the US Pacific Northwest - the coast redwood tree. Growing from a tiny seed, they support vast ecosystems -- and are still, largely, a mystery. Run time 19:28.
Coal Combustion and Acid Rain
The burning of coal in today's industrialized society is one of the reasons for what is known as Acid Rain. (02:04)
Thermal Electricity - How it Works
This is an excellent two-minute mini-documentary that shows through narration and computer animation how fossil fuels are used to generate electricity.
Fossil Fuels - by StudyJams
Heat and pressure have turned the fossils of dead plants and animals into deposits of fuel, such as oil, natural gas, and coal. Fossil fuels are a non-renewable resource, and they create pollution, so it is important to conserve them. Learn more about fossil fuels with this slide show from StudyJams. Details images are set to music while information is written under each photo. A short, self-checking quiz is also included with this link.
Forests in Flux
Science examines the future of the world's forests against a backdrop of climate change and intensifying human activity. This video presentation discusses some of the challenges of global forest governance. (08:54)
The Impact of Climate Change
Learn about how the climate change on earth is influencing the atmosphere. In this video you will also see how weather satellites are used as warning devices for extreme weathers. (05:48)
Climate Change and Health
ABSTRACT: Climate change has multiple direct and indirect consequences for human health. Heat waves affect health directly and are projected to take an increasing toll in developed and underdeveloped nations. The 2003 summer heatwave in Europe -- an event six standard deviations from the mean -- led to 21-35,000 excess deaths in five nations, extensive wildfires, crop failures, nuclear plant shutdowns and melted 10% of the Alpine glacial mass. This event and Hurricane Katrina in 2005 demonstrate
Heat - by StudyJams
Heat is thermal energy that exists in matter. The faster an object's particles move, the more heat it has. Heat can be added to an object by making its particles speed up. There are three basic forms of heat. Learn more about heat with this cartoon animation from StudyJams. A short, self-checking quiz is also included with this link.
How Do You Turn Nuclear Energy Into Electricity?
Nuclear energy creates electricity through fuel rods that are
placed into a moderator to produce heat that is taken out by a heat
exchanger. Discover how nuclear reactors are basically used to create heat with information from a science teacher in this video.
Projectile Motion with Ordered Set Notation
Solving the second part to the projectile motion problem (with wind gust) using ordered set vector notation. This video, which is suitable for high school students, starts with a black screen because the instructor, in his conversational tone, uses it as a 'chalkboard.' Instructor uses different colors for clarification.
Find out what vectors are and how to add them graphically.
'Revolutionary' CO2 Maps Zoom in on Greenhouse Gas Sources
A new, high resolution, interactive map of United States carbon dioxide emissions from fossil fuels has found that the emissions aren't all where we thought.... Run time 04:53.
