Scientific terms

  1. 1. Scientific Terms
  2. 2. <ul><li>Observations : </li></ul><ul><li>Description of objects, events </li></ul><ul><li>May include data from all five senses (touch/texture, smell, taste, sight, sound) </li></ul><ul><li>Could be drawings, diagrams, written words </li></ul><ul><li>Do not include opinions . </li></ul>Observations & Inferences
  3. 3. <ul><li>Observations : </li></ul><ul><li>Qua L itative: description written in words ( L etters) </li></ul><ul><ul><li>five senses (touch/texture, smell, taste, sight, sound) </li></ul></ul><ul><li>Qua N titative: description using N umbers </li></ul><ul><ul><li>Measurements using measuring tools or counting </li></ul></ul>Observations: Types
  4. 4. <ul><li>Inferences </li></ul><ul><li>Drawing conclusions based on observations </li></ul><ul><li>Often provide a reason for the event/object being observed. </li></ul>Observations & Inferences
  5. 5. <ul><li>an educated guess with regards to a specific observation  leads to a question </li></ul><ul><li>tested through a specific experiment </li></ul><ul><li>can be disproven, but not proven to be true </li></ul><ul><ul><li>why not? </li></ul></ul><ul><ul><li>too many factors that could be influencing the experiment to conclude that the hypothesis is completely true for all situations </li></ul></ul>Hypotheses
  6. 6. <ul><li>The common person often doesn’t understand the language used by scientists. And for that reason, they sometimes draw the wrong conclusions about what scientists say. </li></ul><ul><li>Three such terms that are often used interchangeably are &quot;scientific law,&quot; &quot;hypothesis,&quot; and &quot;theory.&quot; </li></ul><ul><li>In layman’s terms, if something is said to be “just a theory,” it usually means that it is a mere guess, or is unproved. </li></ul><ul><li>It might even lack credibility. But in scientific terms, a theory implies that something has been proven and is generally accepted as being true. </li></ul>THeories & Laws
  7. 7. <ul><li>More like a scientific law than a hypothesis . </li></ul><ul><li>Explanation of a set of related observations or events based upon proven hypotheses. </li></ul><ul><li>Verified multiple times by detached groups of researchers. </li></ul><ul><li>One scientist cannot create a theory, he/she can only create a hypothesis. </li></ul><ul><li>Examples : The theory of evolution, the theory of relativity, and the quantum theory . </li></ul>Theories
  8. 8. <ul><li>A statement of fact meant to explain , in concise terms, an action or set of actions. </li></ul><ul><li>Generally accepted to be true and universal by all of the scientific community </li></ul><ul><li>Can sometimes be expressed in terms of a single mathematical equation. </li></ul><ul><li>They are accepted at face value based upon the fact that they have always been observed to be true. </li></ul><ul><li>Examples : The law of gravity, </li></ul><ul><li>Newton’s laws of motion, </li></ul><ul><li>the law of thermodynamics . </li></ul>Laws
  9. 9. <ul><li>Both a scientific theory and a scientific law are accepted to be true by the scientific community as a whole. </li></ul><ul><li>Both are used to make predictions of events. </li></ul><ul><li>Both are used to advance technology . </li></ul>similarities
  10. 10. <ul><li>A theory is much more complex and changes over time. </li></ul><ul><li>A law governs a single action , whereas a theory explains a whole series of related phenomena. </li></ul>Differences
