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
Here is a classic mobile (cell) phone advertisement, which can be incorporated into media literacy instruction to teach the techniques of persuasion as well as the techniques of production. I have created a companion lesson plan which can be found here: (run time :59)
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.
Plant Development: Cell Structure and Function
Professor George Wolfe discusses cell structure and function in this video from Thinkwell's online Biology series. This video uses lecture format and a whiteboard to aid in explanations. Run time 11:07.
Nonvascular Plants - Bryophyta
Video briefly explains the bryophyta division of non-vascular plants. It addresses the reproductive structures and life cycles. The segment is from the program Kingdom Plantae: Builders of Biomes. Run time 03:21.
mosses and liverworts
Non-vascular plants have no true roots, leaves, stems, or flowers. They also have no internal circulatory system for bringing water to the various parts of their bodies. Therefore, non-vascular plants are typically found in very wet places. This video gives a brief overview of two non-vascular plants, mosses and liverworts. Run time 0:50.
3D Animation of a Heart Attack
This 3d medical animation illustrates the story of a heart attack from a blocked coronary artery due to th inflammation of blood vessels. Beginning with damage to the endothelial arterial wall, the animation shows how a white blood cell entering the wall of the artery changes into a macrophage, grabbing and digesting cholesterol. As the cell does its job, it transforms into a foam cell, which, unfortunately, becomes part of the plaque within the blood vessel wall. Ultimately, over a period of
