Scaling Galileo's Solar System - Times
In this activity students calculate how long it takes for planets and moons to complete their orbits, and their velocity, in a scale model solar system. The orbit of Saturn is scaled so it takes one day to circle around campus. Students recreate spreadsheets, shown in a Powerpoint module, with formulas that answer various pieces of the overall question. This module is the third in a series of four on the Galilean Solar System, and was designed for an undergraduate class where students are asked
Redesigning Urban Classrooms to Impact Student Achievement
Because of the No Child Left Behind school reform policies, public schools are gravely scrutinized. This analysis focuses on how to redesign the urban classroom in order to impact student achievement with the intent of being an impetus for better overall school performance ratings. All public school leaders are expected to adhere to the same procedures and guidelines regardless of the population served. The research exposes the fact that there is no comprehensive school reform that is a cure al
Motor System and reflexes - Video for Mobile Devices
Nursing training video for mobile devices: Motor System and reflexes
Students learn that when a figure is flipped over a line to
create a mirror image, the transformation is called a reflection.
Students are then asked to identify the figure that represents a
reflection of a given figure in the x-axis, the y-axis, or a given line
on a coordinate system.
Graphing Systems of Linear Inequalities
In this video, the instructor gives directions on how to find a solution for a system of linear inequalities. He provides an example, then goes through the steps to find the solution that satisfies both inequalities. There is a mistake at the beginning of the lesson which the instructor corrects with some text on the screen.
Graphing Systems of Linear Inequalities
In this video, the instructor goes through the steps needed to graph a system of linear inequalities. He discusses slope, shows how to draw the line on the coordinate plane, and explains what section of the graph should be shaded. There is some shadow on the white board which makes it a little more difficult to see at times during the instruction.
How The Body Works: The Regions Of The Brain
The brain has three major functional and anatomical parts--the forebrain, midbrain and hindbrain. The forebrain consists of the cerebral hemispheres, thalami, hypothalamus and limbic system. The top inch of the brain stem is the midbrain. The hindbrain includes the cerebellum, the pons and the medulla. Video uses animated diagrams. Grades 9-12. 1:16 min.
How Brains Learn to See
Pawan Sinha details his groundbreaking research into how the brain's visual system develops. Sinha and his team provide free vision-restoring treatment to children born blind, and then study how their brains learn to interpret visual data. The work offers insights into neuroscience, engineering and even autism.
How the Body Works : Center of Emotion and Memory
The limbic system, which is concerned with memory and learning, is also believed to be primarily involved in emotional responses. Emotions are the conscious result of the interaction between the activities of the cerebral cortex, the limbic system and the visceral organs of the body which produce specific physical changes. A number of theories have been postulated to explain this relationship between the body and mind. The emotional responses of any individual are, however, also a product of his
Basic overview of the nervous system and how it functions. Describes a single neuron and how each part functions to help the neuron. Color animation with narration. 1:34 min.
Human Anatomy - Working of Neurons
This is a short (3:16), computer-animated video on the central nervous system.
The Central and Peripheral Nervous Systems and the Neuron
Professor George Wolfe discusses the central and peripheral nervous systems and the neuron in this video from Thinkwell's online Biology series. The video uses lecture format along with notes and illustrations on the board. Run time 08:21.
Matricism -part 1
The invention and use of a robotic system to create a painting in oils on canvas. Executed with small units or dabs of medium, the texture, pattern, and color geometries can play equal parts in expressing myriad levels of conciousness, abstraction, thought, motion, or being — beyond the obvious subject of the work.
This video offers an exploration of planet Mars, from early time up to Vicking Landing. Mars is the fourth planet from the Sun in the Solar System. The planet is named after Mars, the Roman god of war. It is also referred to as the "Red Planet" because of its reddish appearance, due to iron oxide prevalent on its surface. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts and polar ic
Rotation, Seasons, and the Surface of Planet Mars
Mars is the fourth planet from the Sun in the Solar System. The planet is named after Mars, the Roman god of war. It is also referred to as the "Red Planet" because of its reddish appearance as seen from Earth.
A terrestrial planet, Mars has a thin atmosphere and surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts and polar ice caps of Earth. It is the site of Olympus Mons, the highest known mountain in the solar system, and of Val
Information and communication technologies (ICTs) systems now dominate our everyday lives. This unit will explain what constitutes such a system and how ICT systems work. You will also look at how ICT systems convey, store and manipulate data, and how they process data. Finally you will learn how these systems are used.
Sintaxis Grafica de la Multimedia (Graphical Syntax of Multimedia)
The multimedia offers an integration that must be made by the subject with the stimuli given, in their majority visual. For that reason it is interesting to know how effective may be the use of images and to propose some basic norms for designing multimedia software based on a graphic syntax
How to Determine the Value of a Coin
This clip shows how to determine the value of a coin. An antique store owner explains that it depends on several factors, including what the coin is made from, if the coin has a mint mistake and if the coin is rare. he gives tips for understand the grading system of coins.
The Real Number Set - Part 2
In this Language of Mathematics video the instructor continues his demonstration of the real number system and how it is broken down. He starts off by speaking of the number zero and the impact of the breakthrough of the 'discovery' of this number.
The Language of Mathematics (23): Cartesian Coordinate System
This video starts in an unlikely place, the instructor's car, where he begins his discussion of the Cartesian Coordinate System.
