What Is a Transgenic Plant?
This 2:45 minute long video explains that a transgenic plant is a plant that has been crossed with another plant and expresses qualities of a stronger, more drought-resistant plant. Students could try this type of experiment in class.
Greater And Less Than of Single-Digit Numbers
In this teacher-made video, the teacher demonstrates use of greater/less than symbols through the use of an alligator puppet. (02:25)
Alligator: Greater than and Less than
With the props of a puppet alligator the lady teaches greater than or less than math problems. She introduces a song that explains what the greater than sign eats. She is very enthused and excited with the presentation.
National Geographic-Cichlid Defense Against Turtle
Have you ever heard of a fish fighting a turtle? Watch these cichlid (SICK-lid) parents keep a hungry terrapin away from their eggs! The commentator talks as if they are at a wrestling match. This is a great teaching resource for elementary/middle school students. It would work well in conjunction with a science lesson on fish, oceans, and animal behavior. This video also helps to build background knowledge. (1:03)
World's Best Natural Wonders - Mount Everest
Part of the BBC series - World's Best Places to See Natural Wonders takes a close look at the world's tallest mountain, Mount Everest. The video shows the location of the mountains, describes how the mountain was created, interviews a few people who have climbed it, tourism around the mountain, and animals that live in the ecosystem.(04:45)
Physical Geography - Forces that Shape Our Earth
Explore the major landforms of our world with spectacular video footage. Look at the various forces that affect our physical environment including glaciers, volcanoes, gravity, rivers, lakes and oceans, movement in the earth, wind and temperature changes. This video is a superb introduction to the ways all these forces work together to shape our planet.
How Does the Earth Change? Part 1
In this brief video, the narrator discusses weathering and erosion.
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)
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
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.
Egg Osmosis Lab
Illustrates Osmosis with Eggs, Corn Syrup and Vinegar
The History of American -Walt Whitman
This program that explores the work of of famous American Authors in history. In the middle of the 19th century major literary figure
Walt Whitman is explored along with his literary works in this
clip.
The Precious Envelope
Without the earth's atmosphere, life would not be possible. Many different gases make up the atmosphere in varying concentrations. Human actions are threatening the delicate balance of these gases. The earth's atmosphere is examined through theories of chemical evolution; ozone depletion and the greenhouse effect are explained.
