Outdoor radio simulation
This unit serves as an introduction to the software A Radio Mobile, a radio simulation tool for outdoor environments. The focus of this unit is on the understanding of the different building blocks of the software. Rather than understanding how to simulate only one specific type of wireless infrastructure the learner should be able to apply the methodology to any kind of wireless system.
Additive number systems: Egyptian
In this session you will learn about the Egyptian number system.
Alphabetic and multiplicative number systems
In this session you will learn about the Greek acrophonic and alphabetic systems and the Hebrew number system.
Size, Scale and Distance
Students will understand how objects in the universe compare in size. Even in a "crowded" region like our solar system, the distances between planets are so vast that they are difficult to imagine.
Site Seeing Intermediate Level
The purpose of this resource is to investigate the idea that every dynamic system has energy and matter in different forms.
This lesson introduces students to the basics of wastewater treatment. Topics include the variety of materials that enter the wastewater system, septic tanks, and municipal treatment systems. Students can review online resources that describe the processes.
Newton's Second Law
This lesson introduces students to Sir Isaac Newton's Second Law of Motion. Topics include the two ways to study the dynamics of a system in which there is motion and a brief description of Newton's work in studying and measuring the motion of objects.
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.
