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.
A Longer Topic Index Draft | ASA Homeschool Science Resources In the last post, Drafting a subject-topic index, I presented a heavily pruned draft of a subject-topic index. In this post I provide a longer, unpruned version. I believe our goal is to arrive at a list that is somewhere in between these two extremes. This index came from several sources. First topics were found from syllabuses and curricula. State standards were were briefly examined. I worked on the list as an outline. The subjects of ‘Technology and Applied Science’, ‘Science as Study’, ‘Science and Christianity’ have not been repeated for this post. Some of these levels are more natural than others. I could use feedback. –Patrick The Outline Astronomy The Cosmos Galaxies and Stars The Solar System Discovery and exploration Sun Planets (Inner planets and Outer planets) * Mercury * Venus * Mars * Jupiter * Saturn * Uranus * Neptune Asteroid belt Dwarf Planets Comets Kuiper belt Earth Science Earth’s Properties, Structure, Composition Seasons Solar intensity Latitude The Earth’s surface Physics

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 History 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.
