In this video, Pexi the Alien asks Alexi why leaves change colors. Alexi explains that leaves make their own food. During the summer, trees take carbon dioxide from the air and water from the ground and make their own food using sunlight and chlorophyll. Trees stop making food in fall therefore making chlorophyll go away. Some leaves are read due to trapped food and some are brown due to waste in leaves. Content is appropriate for elementary students and video would work well in conjunction with a lesson/unit/story on seasons and/or fall.

This professionally-made music video from They Might Be Giants combines clever, cartoon animation with catchy lyrics to help students learn about the process of photosynthesis. Some of the lyrics include, "Chlorophyll cells take in carbon dioxide. Now that's the air that we breathe out.Combines it with water and exposes it to sunlight and that's how plants can make their own food. Photosynthesis is why plants need light and photosynthesis is why humans need plants. Because through photosynthesis plants make oxygen and humans need oxygen to breathe." (01:58)

The Chesapeake Bay receives water from the 64,000 square miles of land surrounding the bay and Landsat satellites are a critical and invaluable tool for characterizing the landscape and mapping it over time. Landsat data provides a baseline of observations for science about how human activities on the land affect water quality, affect wildlife habitat, affect air quality. Without it we wouldn't be able to really understand how sources of nutrients and sediment have changed and where they are in the Chesapeake Bay. (04:27) The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey.

In this video, Nancy Stoltenberg, Director of WBT Certification,
transforms classroom rules rehearsal into an exciting, critical
thinking exercise for her 2nd graders. Using the Because Clapper and the
Example Popper, students expand their understanding of classroom
procedures with surprisingly high level thinking. Note the "air
punctuation" Nancy's kids use to indicate capital letters, periods and
even a comma! Of exceptional interest, this unrehearsed video
demonstrates how an instructor simply using Mirror and Mirror Words can
introduce a complex, multi-partlesson. (15:13)

Natural resources are things occuring in nature, like air, water, sunlight, and crops, that can be used to fulfill a need. Some natural resources, like metals, plastics, fossil fuels, and old-growth forrests, are non-renewable, meaning they cannot be replaced in our lifetime. Learn more about natural resources with this slide show from StudyJams. Vibrant pictures are set to music, while information is written under each photo. A short, self-checking quiz is also included with this link.

Understanding how we define normalcy--the life of a twelve-year-old autistic boy.GEORGE (2000) directed by Corra and Grahame Weinbren is described by Amy Taubin in The Village Voice as “an exceptionally intelligent and moving documentary that explores Corra’s twelve year old autistic son George, who uses his own video camera to make a movie within the movie. In fact, the film is about how we define normalcy.” GEORGE had its American theatrical premiere at The Screening Room, New York City and was exhibited at the Museum of Modern Art, New York, The National Gallery of Art, Washington, D.C., The Gaga Film Festival, Berlin, Germany and aired on HBO in July 2000.(1:26:24)

Enjoy an aerial view of the planet when you set sail in a hot-air balloon with three children and their inquisitive dog. Sung by Susan Reed. Some of the lyrics include "Trains are fun. Cars are fast. Riding bikes down by the river is a blast. Up, up, up, up in a balloon. Up so high, I can touch the moon". Words to the song appear at the bottom of the screen and each word is highlighted as it is sung. This video is beautifully illustrated. Young students will enjoy this story. (02:49)

Volcanoes 101
From NationalGeographicVideo, produced by National Geographic
|

|
|
|

Today we know volcanoes are openings or vents to the interior of the planet. About 1,500 volcanoes around the world are considered active, about 90% rest in the Ring of Fire, a band circling the Pacific Ocean. While the Earth’s surface looks peaceful the crust is made up of slabs of rock that constantly shift, where the plates interact, volcanoes often form. Friction from shifting plates melts the Earth’s crust, causing rock beneath the crust to liquefy. This magma then becomes a volcano by erupting through rifts in the plates. Not all lava is the same. Volcanoes can be deadly, but it can also be good, it created 80% of Earth’s surface and the air we breathe, rich soil for farming, and some countries harness the heat to create geothermal energy. Video is very interesting and good quality. Good for elementary grade and middle school students.

Jazz filled the air and wailed against the night. Caught in the sway,
American prose writers sought out the forbidden - the slang, the
dialects, and the rhythms of the folk and of everyday life. Writers such as Hemingway, Stein, and Fitzgerald forged a new style: one which silhouetted the geometry of language, crisp in its own cleanness.

This picture book admirably conveys the miracle of a seed. Flower pods burst and dispatch their seeds on the wind; the air-borne seeds are subject to myriad disasters; and the ones that make it through the perils of the seasons to become mature flowering plants are still susceptible to being picked, trod upon and otherwise damaged. But nature allows for survivors, and so the tiny seed grows into a giant flower, releasing its seeds and continuing the cycle. The words are displayed on the screen as they are read. (9:59)
