Models in Science 1. Semantics: Models and Representation Models can perform two fundamentally different representational functions. On the one hand, a model can be a representation of a selected part of the world (the ‘target system’). Depending on the nature of the target, such models are either models of phenomena or models of data. ChronoZoom ChronoZoom is an educational tool for teachers and students who want to put historical events in perspective. A great many resources have been created already in ChronoZoom for your enjoyment and enlightenment. Start Exploring World War I Timeline Timelines are one of our favorite history tools and an important element of the Layers of Learning curriculum. Here are some WWI events to add to a timeline. You may find more from your reading. You can put the timeline squares on a wall or in a notebook. And here is the set of printable World War I Timeline squares. A Little History

What Is a Controlled Experiment? - Definition and Example Updated December 05, 2014. Question: What Is a Controlled Experiment? One of the most common types of experiment is a controlled experiment. Here is a look at what a controlled experiment is and why this type of experiment is so popular in science. Annenberg Media Exhibits: Collapse Hundreds of years ago in what is now modern Honduras, Copán was a thriving civilization, a center of the cultural life of the Maya. Tens of thousands of people made their home in the Copán Valley. Yet despite its importance, Copán went into decline. Across the vast territory of the ancient Maya, other important sites were sharing a similar fate. Timeline DoomsdayClock_black_3mins_regmark.jpg 2015: "Unchecked climate change, global nuclear weapons modernizations, and outsized nuclear weapons arsenals pose extraordinary and undeniable threats to the continued existence of humanity, and world leaders have failed to act with the speed or on the scale required to protect citizens from potential catastrophe. These failures of political leadership endanger every person on Earth.” Despite some modestly positive developments in the climate change arena, current efforts are entirely insufficient to prevent a catastrophic warming of Earth.

What is the Correlation of Science with other Subjects? Correlation of Science with other Subjects As known that for over all development of the students, various subjects are being included in the curriculum. These subjects are not selected on ad-hoc basis, but this decision is taken after proper consideration and analysation. Generally those subjects are included in the curriculum which is found to be complementary to each other, as the main objective of all of them is to achieve set objective of education that is to bring about over all development of the students. Science is quite a complex and vast kind of subject, because of which the task of correlating it with other subjects of curriculum seems to be quite an easy task. Deliberate effort should be done by the science teacher to bring about co-relation in between the science and other subjects of the curriculum, which are being imparted to the students.

Magna Carta: Cornerstone of the U.S. Constitution At the death of his brother, Richard the Lionhearted, John assumed the throne of England, intent on exercising power to achieve his own selfish ends. To fund military campaigns in France, he extracted exorbitant fees from nobles, who, in turn, raised the rents imposed on their tenants. At the same time, John reduced the lords' customary powers over those tenants, restricting, for example, their power to hold court for those living on their feudal lands. He attempted to influence church elections and confiscated church properties, alienating the powerful ecclesiastical establishment and depriving the poor of the only source of relief available to paupers. He restricted trading privileges traditionally granted to London's merchants and increased their taxes, alienating this constituency as well. King John's tyrannical practices extended to demanding sexual favors from the wives and daughters of his barons and to imposing brutal punishments on individuals who challenged his authority.

Global Connections . Science and Technology Cellular phones, for example, are increasingly popular in the Middle East, providing telephone access in more remote communities as well as in crowded urban areas. Wireless service bypasses the difficult and expensive requirements for laying out and maintaining telephone cables. Satellite television news stations like Al-Jazeera provide new and varied sources of information to people in the Middle East who once had access only to government-controlled media.
