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