A History of the World - Location - Europe 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. 1.1 Representational models I: models of phenomena Many scientific models represent a phenomenon, where ‘phenomenon’ is used as an umbrella term covering all relatively stable and general features of the world that are interesting from a scientific point of view. A first step towards a discussion of the issue of scientific representation is to realize that there is no such thing as the problem of scientific representation. The second problem is concerned with representational styles. Although this question is not explicitly addressed in the literature on the so-called semantic view of theories, some answers seem to emerge from its understanding of models. Scale models. 2.
Timeline World 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. Answer: A controlled experiment is one in which everything is held constant except for one variable. Example of a Controlled Experiment Let's say you want to know if type of soil affects how long it takes a seed to germinate. Why Controlled Experiments Are Important The big advantage of a controlled experiment is you can eliminate much of the uncertainty about your results. Are All Experiments Controlled? No, they are not. Learn More What Is an Experiment?
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 Also known as the Great War and the War to End All Wars (sure wish that had worked out), the First World War changed everything. It had absolutely nothing to do with America, yet America fought in it and emerged the world leader. This is a painting by artists Wilie Stower of the Battle of Dogger Bank, 1915. WWI started because of European leaders’ posturing for power. On the Web I found a whole series of great printable resources for World War I here. And here is an excellent animated map of the Western Front from the BBC. This is a map of the Western Front in 1914.

Timeline DoomsdayClock_black_2.5mins_regmark (1).png 2017: For the last two years, the minute hand of the Doomsday Clock stayed set at three minutes before the hour, the closest it had been to midnight since the early 1980s. In its two most recent annual announcements on the Clock, the Science and Security Board warned: “The probability of global catastrophe is very high, and the actions needed to reduce the risks of disaster must be taken very soon.” In 2017, we find the danger to be even greater, the need for action more urgent. DoomsdayClock_black_3mins_regmark.jpg 2016: "Last year, the Science and Security Board moved the Doomsday Clock forward to three minutes to midnight, noting: 'The probability of global catastrophe is very high, and the actions needed to reduce the risks of disaster must be taken very soon.'

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. Science and Language: To co-relate science with language subjects, students can be asked to write essays on some scientific topic.
