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.
Chloroplast
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.
30 Years Apple
A little fanvideo made by iMovie. Images of Jobs and Wozinak as well as the evolution of the different types of computers. No text or narration. (5:27)
Issues in computer supported inquiry learning in science
Computer supported inquiry learning has become an important application of computers in education. Computers allow for providing resources for inquiry learning, such as simulations; built-in support for the processes of inquiry learning; support for collaborative learning scenarios as well as tools for modeling by learners. An overview of the main issues on research on computer supported inquiry learning is provided including issues such as assessing learning effects of computer support, gaming
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
C++ Console Lesson 19: Function Templates
More at http://xoax.net
This C++ video tutorial shows how to create and call function templates. Function templates are special functions that can operate with generic types. This allows us to create a function template whose functionality can be adapted to more than one type or class without repeating the entire code for each type.
Gulf Oil Spill Effects On Wildlife
'New reports are surfacing every day about the immediate impacts of the Deepwater Horizon oil spill on Gulf Coast wildlife, especially as the oil reaches the sensitive marshlands along the coast. But how will these communities be affected over time? Scientists currently know very little about how long it takes for the hydrocarbons and heavy metals in crude oil to work their way through marine food webs. To address this issue, California Academy of Sciences researcher Peter Roopnarine is working
Ocean Tides
Tides are the rise and fall of the ocean's surface. Learn more about ocean tides in this educational video from dizzo95. The video briefly explains the causes of the tides, types of tides, and how often a tide occurs. More videos about tides can be found under the category and subcategories of Astronomy/Solar System/Earth's Moon/ Moon and Earth's Tides. Run time 0:55.
Reading a Pictograph
A whiteboard presentation demonstrating three pictograph. The off-screen narrator describes how to read a single symbol pictograph and different types of two-symbol pictographs. Descriptions are clear.
Following Directions with Goofy
This animated video explains why directions are so important. It shows Goofy a variety of examples in which directions are important and explains what would happen if there weren't directions. Lots of real life examples of directions are given. Visual, spoken, and written directions are also described. Signs are an example of visual directions. Spoken directions include those from a teacher. Written directions include those used to help assemble items. T
Inside a Solar Cell
In this interactive activity adapted from NOVA Online, learn how a typical photovoltaic cell converts solar energy into electricity. Explore the components of a photovoltaic cell, including the silicon layers, metal backing, antireflective coating, and metal conductor strips. Using animations, investigate why the silicon layers are doped with phosphorous and boron, and how an electric field is used to generate electricity from sunlight. No audio.
