The tropical rainforests of the world are home to thousands of species of plants and animals -- including many that remain undiscovered by scientists. This video segment from the Race to Save the Planet teaching module "Saving the Diversity of Life" explores both the ecological importance and fragility of the rainforest biome and its organisms. Run time 01:45.
The desert biome is characterized by low precipitation, a high rate of evaporation (seven to fifty times as much as precipitation), and a wide daily range in temperature. The dramatic temperature fluctuations are the result of low humidity, which allows up to 90 percent of solar radiation to penetrate the atmosphere and heat the ground during the day, then for this accumulated heat to be released back into the atmosphere at night. Precipitation in deserts, unlike other biomes, is highly irregula

How Changes in Earth's Magnetic Field and Ionosphere Affect Us - Part 4
Part 4 in a discussion on How do changes in Earth's magnetic field and ionosphere affect us? Anya Strømme – EISCAT/SRI International. She’s working with very high power radar to study the aurora borealis which are better observed at higher latitudes. She’s studying particles coming into the atmosphere, heating it, generating currents—this is where our satellites fly…this impacts tv reception, GPS, cell phones in a much more dramatic way than we can imagine. Run time 03:16.
The Power House of the Cell
Mitochondria play host to one of the most important processes in your
body: cellular respiration. Taking in glucose and oxygen, mitochondria
produce energy, which they capture and package as energy-rich molecules of ATP. This video describes the structure and functions that give mitochondria their nickname: the powerhouses of the cell. Closed captioning included. Run time 05:47.
How does HIV spread from an infected cell to a healthy one? A team from the University of California, Davis, and Mount Sinai School of Medicine in New York captured the process on video for the first time. By dying viral particles with a fluorescent green dye, they were able to see the infection in action.
This is a video clip from "Adaptations", a 14-minute award-winning elementary life science video produced by the Visual Learning Company. This brief clip gives an overall view of what animal adaptations are, and how they are different for different species of animals. Examples include herbivores with flat teeth, carnivores with sharp teeth and claws, and plants with broad leaves to capture sunlight. Run time 01:43.
Exchanges in the New World
Columbus’s famed voyage in 1492 joined two very different worlds. For thousands of years, Europeans and Native Americans lived completely separate lives, unaware of the others’ existence. When Columbus stepped onto the rocky soil of San Salvador, he started a historic chain of events that affected the lives of millions of people on both sides of the Atlantic.
Columbus and later explorers discovered a land unlike anything they had experienced. They encountered neatly patterned park-like
Garden safety for children
It can be fun to let young children play in a garden but experts warn of some of the dangers to look out for. Tools, chemicals and water are the biggest hazards; and certain plants and flowers also must be avoided. This video shares this important information.
Magic School Bus "Gets Eaten"
Join Ms. Frizzle and the class as they search for a connection between pond scum and tuna fish. Scum is a kind of algae and algae and tuna are part of the same food chain! This Magic School Bus episode will cover the following two concepts: (1) Living things are linked by what they eat and what eats them. and (2) Almost all food chains begin with plants. Run time 22 minutes.
Learn Why Animals Eat Other Animals
Crazy Chris shows you a real life food chain you can do right at home with your exotic pet. Chris uses lettuce, a cricket, and a tarantula to demonstrate a food chain. He then explains why some animals eat plants (herbivores) while others eat meat (carnivores.) Run time 03:00.
A Bamboo Garden
Almost 30 years ago, Jerry Burton got rid of some mute swans from his pond and in return received a few bamboo plants. It was the start of a lifelong love of bamboo, which is now a full-time business. Run time 05:16.
Hoover found himself pitted against Democratic nominee Franklin Delano Roosevelt (FDR), governor of New York State. Besides being a Democrat, which in this election was a benefit, Roosevelt was blessed with charm, wit, intelligence, and self-assurance. He was also a mesmerizing speaker, which in this era of the radio was crucially important. Roosevelt had a resonant voice and a gift for employing phrases that struck a strong chord with his listeners. In a campaign speech, he used the term "forgo
Role of the Sarcoplasmic Reticulum in Muscle Cells
The instructor in this video, Sal Khan, discusses the role of the sarcoplasmic reticulum in controlling calcium ion concentrations within the muscle cell. Mr. Khan uses the Paint Program (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education.
Anti-Semitism: A History
An excellent video that goes through the history of the term, the treatment of Jews through the years, and the Jewish culture. Relates to both Christians and Muslims. Needs a word list, map, and could benefit from a timeline. Very well done. Good for most grade levels and is one of the best videos on this topic
Children's Choice afterschool enrichment program: Life's a Lab - Science Club. In this lesson we explore the science of the colors of both white light and black ink, chromatography, super absorbent polymers, and the water and soil nutrient uptake function of root systems of plants.
Setting Up a Chemistry Experiment to Test Ph of Acids & Bases
Setting Up a Chemistry Experiment to Test Ph of Acids & Bases. Part of the series: Chemistry Lesson: Ph Tests for Acids & Bases. When conducting a chemistry experiment on the acid level of various household substances, begin with a hypothesis on whether or not a substance is acid-based. This two minute video goes rapidly and students would benefit from a word wall and to have the experiment in front of them to practice after the video is shown.
Busy, Busy, Bees! Honey Bees and Drones
We all know of honey bees! These insects are famous for two things:
when they are angry, they sting, and it hurts! And they convert nectar
which they collect from different plants into a sweet, thick, golden
liquid we know as honey!
Bees live in hives composed of hexagonal spaces and their colonies
have clear hierarchies. The most important member of the hive is the
queen bee. The other kinds of bees are female worker bees which nurse
the eggs and
