The applets in this section of Statistical Java allow you to see how levels of confidence are achieved through repeated sampling. The confidence intervals are related to the probability of successes in a Binomial experiment.
Using data from the National Climate Data Center (NCDC) track snowfall in your area and assess snowfall levels from the Winter Olympics.
Global energy use increases by the day. Polluting the atmosphere with ever more carbon dioxide is not a viable solution for our future energy needs. Can new technologies such as carbon sequestration and ethanol production help provide the energy we need without pushing the concentrations of CO2 to dangerous levels?
How to Put Out a Grease Fire
A short video that does an excellent job of explaining how to put a grease fire out. A must view for all age levels.
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.
A United Streaming Video. Said by the 16th President of the United States Of America, Abraham Lincoln. Do you need to memorize the Gettysburg Address or maybe just want to hear the words again? It doesn't matter, this video is to let you know the Gettysburg Address. Pictures are used as the background to the reading of the Gettysburg Address. Video is of great quality and good for all elementary grade levels.
Measurement: The Foundation of Chemistry
The distinction between accuracy and precision and its importance in commerce and science are explained. Numerous examples of real world use of chemical measurement are shown. Various equipment is used to demonstrate specific levels of precision.
Schizophrenia: Pharmacological Treatment
Dr. Arnold Scheibel reviews the various ways in which schizophrenia has been treated since the 1950s, ranging from the use of physical restraints and cool baths to the administration of antipsychotic drugs. He and other psychiatrists elaborate on the ways in which drugs alter the chemistry of the brain. Drugs that are effective seem to reduce the levels of dopamine in th
Living With Amnesia: The Hippocampus and Memory
Amnesia appears in many different forms. This module shows how the extent and location of damage can result in varying levels of memory impairment. Footage of Mike, an amnesic individual, demonstrates the result of an injury to the hippocampus. Mike’s reaction to his memory deficit and drastic coping measures underscore the importance of memory to everyday functioning.
In certain situations, microbial control is a necessity. For instance, our food system requires sanitary conditions and hospitals require sterilization techniques. Here we see the options available for various levels of microbial control.
Treating Drug Addiction: A Behavioral Approach
Provides an example of how drug therapies incorporate the results of research on several levels of behavior, and shows how patients learn to deal with environmental triggers for cravings.
Energetics and Dynamics
This program emphasizes the importance of learning about energetics and dynamics in order to improve students’ understanding of basic principles of chemistry. The complexity of teaching concepts such as the collisions theory, reaction kinetics, and electronic energy levels is introduced using a variety of teaching strategies. These concepts are related to everyday phenomena thro
HIV and AIDS
Studying individuals with natural resistance to HIV has led to insights into the infection process and may produce new treatments or a vaccine. This session explores recent developments in the study of HIV and AIDS, the future global impact of the current infection levels, and the ethical issues surrounding current research and treatments.
Healthy School Meals and Educational Outcomes
This is a research report published by the Institute for Social and Economic Research (ISER) that examines the impact of introducing healthy school meals on educational outcomes, as measured through Key Stage 2 test scores, within a single Local Authority. Claims are made that, following the implementation of the Jamie Oliver 'Feed Me Better' campaign in 2004, improvements were noted for test scores in English and science, and levels of authorised absence were reduced.
This video will show how to do a gymnastics floor routine and talks about point levels.
Social Alternatives in the Progressive Era
This video is accompanied by text. "During the Progressive Era, lawmakers at both state and federal levels introduced laws and regulations to protect citizens at home and work. Although many states had already passed social-minded legislation before the Progressive Movement, many of the laws were poorly written and could not be adequately enforced. For example, in 1874, Massachusetts restricted women and children workers to 10-hour workdays. In 1882, New York attacked the sweatshops by prohibiti
Tutorial Letter: General Information and Overview of Programme
In this module we will introduce you to concepts such as food security, food insecurity, nutrition security, livelihood security, food policies and programmes and the role of stakeholders and facilitators. You will gain the knowledge and skills required to gather information on many different levels, from the macro to the micro level. You will also, in time, become equipped to analyse community and household needs, understand the implications of policies and strategies for communities and househ
2.2 Persistent currents lead to constant magnetic flux An important consequence of the persistent currents that flow in materials with zero resistance is that the magnetic flux that passes through a continuous loop of such a material remains constant. To see how this comes about, consider a ring of metal, enclosing a fixed area A, as shown in Figure 6a. An initial magnetic field B0 is applied perpendicular to the plane of the ring when the temperature is above the critical temperature of the material from which the rin

Have you ever wondered why overheating on a hot day and getting a fever when you're sick feel so different? Both involve an increase in your body's temperature. However, in one case your brain and body do everything they can to cool you off, while in the other they push the temperature inside your body to extreme levels. This video describes these two responses in detail and takes some of the mystery out of fever. The video also gives a simple introduction to homeostatis. Closed captioning inclu
Spanish Lesson - formal vs. informal
A very basic introduction to the difference between tú and usted. Figure out how to use different levels of formality along with some good examples in Spanish. (The quality could be a little better.)
