Video is good quality and has information for students studying this area of the United States.
Lewis and Clark
Join Lewis and Clark as they journey overland across North America in this short, computer-animated video. The following concepts will be briefly addressed: the Lewis and Clark Expedition, the Louisiana Purchase, President Jefferson commissions survey, Lewis and Clark meet natives, Lewis and Clark discover new plants and animals, Lewis and Clark reach the Pacific Ocean, and Lewis and Clark return home as heroes. The video ends with a 10-question, fill-in-the-blank quiz.
How Do Changes in the Earth's Lower Atmosphere Affect Us? - Continued
How do changes in Earth's lower atmosphere affect us? (continued) Jeff Thayer – University of Colorado continues the discussion of How do changes in Earth's lower atmosphere affect us? We are so dependent on our space assets, our satellites, cell phones and GPS. The atmosphere breathes and the satellite senses these changes and is impacted by it. We are very Earth centric, so we are just beginning to explore all there is of space. Run time 03:14.
Taking Atheism to the General Public - Edward Tabash (3/3)
Atheist Talk cable program by Minnesota Atheists. "Taking Atheism to the General Public - Edward Tabash" recorded 12/2/2006 What's ... all » the best way for us to bring the good news of atheism to the public? Should we "bash" religion? Nationally known atheist speaker Edward Tabash will give us some tips. Edward Tabash is chair of the national legal committee for Americans United for Separation of Church and State. He is an atheist debater and chairs the First Amendment Task Force for the Coun
This animation is a very simplified description of the light-dependent reaction of photosynthesis, a unique biological process in which light energy (sunlight) is converted to chemical energy (adenosine triphosphate). The light-independent reaction takes place in all eukaryotic photoautotrophs (plants, algae, etc.). The process shown here occurs in less than a trillionth of a second, constantly (when light is available) and in great abundance.

Magic School Bus Gets Planted
Join Ms. Frizzle and the class as they travel inside a plant and learn more about photosynthesis and what helps a plant grow. This Magic School Bus video will teach the following two concepts: (1) Plants need food to live and grow. Instead of finding food to eat, plants use water, sunlight, and air to make their own food. and (2) Plants make surgar, the basic food all living things need to live and grow.
Learn about Fuel Cell Technology
Many researches have been working on renewable, clean energy sources. This particular study shows how hydrogen may some day replace gasoline to fuel our vehicles with zero emission of fuel cells. Learn about real world testing of this fuel cell technology. Run time 01:50.

Sand Dune Investigation
From Dragonfly TV. Victoria and Alejandra Sand visit the Guadalupe-Nipomo Sand Dunes. In some cases, dunes will move as much as 10 feet in just a few days. Others don't move much at all. Dunes come in all shapes and sizes but the girls didn't understand why some dunes are full of plants and others aren't. So they decided to investigate and hiked over three kinds of dunes. The fore dunes were right next to the ocean. The scrub dunes were about a mile inland. Two miles inland were the big,
The Intel 386 Story for Kids
[Recorded Feb 4, 2009] Today, many American teenagers enjoy a life enriched by an almost pervasive level of technology. Teens live surrounded by laptop computers, gaming systems, cell phones, and DVD and MP3 music players. All of these technologies have been made possible through increasingly smaller, cheaper and more powerful microprocessors often developed and sold by Intel. In this lecture, Professor Richard Tedlow targets his talk at teenagers to explain a part of the microprocessor technolo
School Safety And Technology: Important Issues for All Schools
Beware of the ad that starts the video.
There are many issues that every school needs to address. Especially important is the privacy issues and what happens in an emergency and the lines are blocked from administration use
These issues are addressed in this short video:
How can cell phones impact school safety?
How can digital cameras impact school safety?
How can computers pose a threat to school safety?
What steps should schools take to protect s
Cell Phone Facts : How Do Cell Phones Work?
Beware of the ad at the beginning. Very political. Cell phones work by transmitting a signal to a tower, which in turn sends signals to either land lines to other towers. Find out why cell phones have trouble and how they work. World's worst artist does not help.
Deconstructing A Television Commercial: Media Literacy

Parts of a Plant Cell
This short video explains each of the organelles inside a plant cell and especially addresses the organelles that differ from an animal cell. The video also briefly explains photosynthesis while discussing the chloroplasts in a plant cell. Run time 02:56
Plant Cell Motility and Laser Microsurgery of Cytoplasmic Strands
Plant cells are shaped by rigid cell walls. Osmotic forces press the plasma membrane tightly against these walls. The walls can be removed with enzymes. The remaining structures, the protoplasts, are now bordered by the plasma membrane. Since the shaping force of the wall is missing, isolated plant protoplasts are usually perfectly spherical in shape as a result of non-directional osmotic forces. Run time 04:19
Elodea Cytoplasmic Streaming
About 10-15 minutes after preparing a wet mount of an elodea leaf, evaporation of some of the water makes it possible to see chloroplasts in motion inside of the cytoplasm. "Cytoplasmic streaming" is defined as the movement of the fluid substance (cytoplasm) within a plant or animal cell. This is the mechanism for the transport of nutrients. Run time 02:31.
This short, animated video is a biology group project where students were asked to make a commercial about an organelle in a plant cell. The chloroplast in this commercial is a restaurant called "Le Chloroplaste". The "chef" explains what ingredients he uses to make gluclose in the process of photosynthesis. Run time 01:04.
