what is science
What is Science?
  • Science is a way of knowing about the world and making sense of it.
what is science1
What is Science?
  • Science is progressive and constantly changing.
    • Progressive- It advances and builds upon previous ideas
    • Changing – Scientific knowledge is not completely certain
      • New ideas, experiments, technology, etc allow for scientific ideas to be changed, altered, or adapted
      • This change is often opposed or unwelcomed.
        • Ex – Copernicus, Galileo
  • Science is in NO WAY absolute or final!!!!
about science1
About Science
  • Math is NOT science - it is only a tool used in science.
    • Equations in Science - shorthand ways of seeing and understanding the connections and relationships of nature
      • Are used as a guide to thinking - they help us understand the concepts.
      • Are useless unless the concepts are understood.
the scientific method
The Scientific Method
  • A method based on logical, or ordered, thinking and experimentation.
  • It is a useful tool that guides scientific work, but doesn’t always follow the same order.
  • There are 5 basic steps
scientific method
Scientific Method
  • 1. Observation - Recognize a question or a problem - one must have a desire or need to figure something out.
    • Five senses are used!

  • 2. Hypothesize - A hypothesis is an educated guess that must be testable.
      • It is the basis for experimentation

  • 3. Experiment - test to see if the hypothesis is correct.
      • Must be repeatable - one must get the same results over and over.

  • 4. Analyze the results of the experiment
      • How do the experimental results compare to your hypothesis or prediction?

  • 5. Form a conclusion - the conclusion organizes the observations, hypothesis, and the analysis of the experiment.
      • Rules are inferred, or concluded, from the evidence gathered from the 3 previous steps.
theory
Theory
  • A set of ideas that have been repeatedly tested, and the same results have occurred for each test.
observation vs inference
Observation vs. Inference
  • Observation – Made using the 5 senses
  • Inference – Use prior knowledgeand experiences
