Differentiation in Plants - Elementary Science
This is a short, animated narrated video (01:40) gives a very brief overview of the differentiation in plants. Some of the narration is accompanied by English captions.
Plant Physiology: Phototropic Response
Growth in plants reflects the way in which the interact with the environment. Using time lapsed photography, his professional video shows how a plant responds to light and gravity. Includes narration. Run time 02:36.
Hydroponics is a method of growing plants using mineral nutrient solutions, in water, without soil. Visit the VanScoy farm to see how its hydroponic operation is progressing.
Biome in a Bag
The distribution of plants and animals around the world corresponds closely to global patterns of temperature and rainfall. This is why two forests half a world away from each other will often have very similar organisms living in them. In this ZOOMSci video segment, a cast member of ZOOM creates a self-contained biome and explores evaporation, condensation and precipitation. The video also addressed what a plant needs in order to grow. Closed captioning included. Run time 03:24.
This interactive activity adapted from Indiana University features time-lapse videos that reveal the movement and growth of plants in their pursuit of light. Although plants have no choice about where they are rooted, they do respond to environmental cues in ways that enable them to survive. This interactive site includes five videos using time lapsed photography (no audio) with written explanations. The videos include: seed germination and gravity, light and dark responses, twining vines, pl
The experiment demonstrated in this ZOOMSci video segment--wearing an old sock through a grassy or weedy field, planting the sock, and watching what grows--will not only give young scientists a better idea of the kinds of plants growing in their area, but will also help them begin to think about the evolutionary strategies of plants. Closed captioning included. Run time 03:00.
Risk Factors For Squamous Cell Carcinoma -
Doctor identifies risk factors for squamous cell carcinoma, a type of skin cancer. Video explains why certain people are at much higher risk for this deadly cancer. 59 sec.
Understanding Basal Cell Carcinoma
Video has a doctor explaining what basal cell carcinoma is and who is at risk. Basal cell carcinoma is the most common form of all cancer. Images show what to look for in identifying this cancer. 3:11 min.
NASA to Launch R2 to Join Space Station Crew
NASA will launch the first human-like robot to space this year to become a permanent resident of the International Space Station. Robonaut 2, or R2, was developed jointly by NASA and General Motors under a cooperative agreement to develop a robotic assistant that can work alongside humans, whether they are astronauts in space or workers at GM manufacturing plants on Earth.
Macroporous hydrogels as vascularizable soft tissue â implant interfaces: materials characterizat
Implantable medical devices, such as biosensors and implantable drug delivery systems, function optimally when rapid solute exchange can occur between implant and surrounding tissue. However, almost all materials implanted into the body are encapsulated in a fibrous layer that prevents this rapid communication. Macroporous materials are known to change this response by allowing vascularized tissue ingrowth, however many questions still exist as to the role material properties play. In this work,
Plate Tectonics - the Movement of Continents California and Australia used to be neighbors and Brazil was close to or connected to Nigeria. What drives the engine of plate tectonics remains a mystery.

This video segment adapted from KQED's QUEST profiles the work of Jay Keasling, a synthetic biologist experimenting with ways to produce a cleaner-burning fuel from biological matter, using genetically modified microorganisms. Keasling's approach involves engineering microbes to eat simple sugars found in plant matter and then excrete fuel. The video explains the two techniques that may enable Keasling to accomplish this: metabolic engineering and directed evolution. It also suggests that creati
New Model for Juvenile Justice
A 7 minute video summarizing Missour;s new approach to juvenile justice. This new method for juvenile detention has seen surprisingly successful results, trading in the orange uniforms and cell blocks for therapists and dorm rooms.
In this task we’ll look at monitoring the risks and identifying and implementing control measures. it contains a learning pack which addresses the issues surrounding the treatment of risks; strategies you will use control and assess both the ongoing and the short term nature of the risk; differing strategies in risk management; various models and devices to monitor risk.
the naming and classification system as applied to plants - part of the process of plant identification.
From Embryo to Duckling
This video segment from NOVA: "The Shape of Things" charts the development of a duck embryo, from its earliest stages just after fertilization, through cell replication and differentiation, to the final stage, emergence from the protection of the eggshell. Closed captioning included. Run time 01:19.
Design of an eLearning System for Accreditation of
This paper deals with issues related to the non-formal learning in vocational education, and the role of ICT for providing appropriate accreditation model in such education. The presented conclusions are based on the Leonardo da Vinci project LeoSPAN. The paper emphasises on the development of a model and a prototype of an adaptive eLearning system that ensures the pre-defined learner outcomes. One of the advantages of the eLearning system is the flexibility for people who upgrade and improve th
Museum Separates Iconic Battling Dinosaurs in Rotunda
The American Museum of Natural History began the process of separating two long-time combatants -- barosaurus and allosaurus skeletons -- that have shared the same display mount in the Theodore Roosevelt Rotunda since they were first installed in 1991. The separation kicked off with curator Mark Norell overseeing the first ceremonial cut in the mount. By the end of the six-week project, an eight-food-wide pathway will be cut through the dinosaur mount to allow visitors to walk between the tower
