Transcript of "What Is Science"

  1. 1. Chapter: The Nature of Science Section 3: Science and Technology Section 1: What is science? Section 2: Doing Science 1
  2. 2. Chapter: The Nature of Science Table of Contents Section 3: Science and Technology Section 1: What is science? Section 2: Doing Science
  3. 3. <ul><li>Science is a way or a process used to investigate what is happening around you. </li></ul><ul><li>It can provide answers to many questions. </li></ul><ul><li>Tools, such as thermometers and metersticks, are used to give numbers to descriptions. </li></ul>Science in Society What is science? 1 <ul><li>Scientists observe, investigate, and experiment to find answers. </li></ul>
  4. 4. <ul><li>Throughout history, people have tried to find answers to questions about what was happening around them. </li></ul><ul><li>Early scientists tried to explain things based on their observations. </li></ul>Science Is Not New What is science? 1 <ul><li>They used their senses of sight, touch, smell, taste, and hearing to make these observations. </li></ul>
  5. 5. <ul><li>Cholera is a disease caused by a bacterium that is found in contaminated water. </li></ul><ul><li>People who eat food from this water or drink this water have bad cases of diarrhea and can become dehydrated quickly. </li></ul>Science as a Tool What is science? 1 <ul><li>They might even die. </li></ul>
  6. 6. <ul><li>E. Coli is another type of bacterium that can contaminate modern food and water supplies. </li></ul><ul><li>Some types of E. Coli are harmless, but others cause intestinal problems when contaminated food and water are consumed. </li></ul>Science as a Tool What is science? 1 <ul><li>Science can be used to compare how people tracked down the source of the cholera in 1871 with how they track down the source of the E. Coli now. </li></ul>
  7. 7. <ul><li>People in the past followed clues to track the source of cholera epidemics and solve their problem. </li></ul>Using Science Every Day—Scientists Use Clues What is science? 1 <ul><li>Today, scientists do the same thing by finding and following clues to track the source of E. Coli in food and water supplies. </li></ul>
  8. 8. <ul><li>Scientists use prior experience to predict what will occur in investigations. </li></ul>Using Prior Knowledge What is science? 1 <ul><li>Scientists form theories when their predictions have been well tested. </li></ul><ul><li>A theory is an explanation that is supported by facts. </li></ul><ul><li>Scientists also form laws, which are rules that describe a pattern in nature, like gravity. </li></ul>
  9. 9. <ul><li>Scientists use skills and tools to find the similarities and differences. </li></ul>Using Science and Technology What is science? 1 <ul><li>They use a variety of resource materials to find information. </li></ul>
  10. 10. Using Science and Technology What is science? 1 <ul><li>The computer is one tool that modern scientists use to find and analyze data. </li></ul><ul><li>The computer is an example of technology. </li></ul><ul><li>Technology is the application of science to make products or tools that people can use. </li></ul>
  11. 11. <ul><li>Doctors and scientists use skills such as observing, classifying, and interpreting data. </li></ul>Science Skills What is science? 1
  12. 12. <ul><li>Sometimes observation alone does not provide a complete picture of what is happening. </li></ul>Observation and Measurement What is science? 1 <ul><li>To ensure that your data are useful, accurate measurements must be taken, in addition to making careful observations. </li></ul>
  13. 13. Observation and Measurement What is science? 1 <ul><li>Comparing and contrasting are other important skills. </li></ul><ul><li>When scientists look for similarities among data, they compare them. </li></ul><ul><li>Contrasting the data is looking for differences. </li></ul>
  14. 14. <ul><li>The results of observations, experiments, and investigations are not of use to the rest of the world unless they are shared. </li></ul>Communication in Science What is science? 1 <ul><li>Scientists use several methods to communicate their observations. </li></ul>
  15. 15. Communication in Science What is science? 1 <ul><li>Results and conclusions of experiments often are reported in one of the thousands of </li></ul>scientific journals or magazines that are published each year.
  16. 16. <ul><li>Another method to communicate scientific data and results is to keep a Science Journal . </li></ul>Science Journal What is science? 1 <ul><li>Observations and plans for investigations can be recorded, along with the step-by-step procedures that were followed. </li></ul><ul><li>Listings of materials and drawings of how equipment was set up should be in a journal, along with the specific results of an investigation. </li></ul>
  17. 17. <ul><li>You should record mathematical measurements or formulas that were used to analyze the data. </li></ul>Science Journal What is science? 1 <ul><li>Problems that occurred and questions that came up during the investigation should be noted, as well as any possible solutions . </li></ul><ul><li>Your data might be summarized in the form of tables, charts, or graphs , or they might be recorded in a paragraph. </li></ul>
