  • 1. Chapter 1 The Nature of Science
  • 2. Science and Technology Section 1-1 H.W. pg.12 Ques. 1,2
    • What is Science
    • Science is the process of trying to understand the world around you.
    • ● What do you call someone who practices science?
    • A scientist
    • ● We use science to create technology.
    • Technology is the use of knowledge learned through science
    • Examples of Technology
    • Computers, machines, cars.
  • 3. Doing Science Section 1-2 H.W. Pg. 10 Ques. 1-10
    • Whenever you do science you want to solve a problem . What are some problems that you can solve?
    • - Why does a plant grow?, How do we use oxygen?
    • In order to solve your scientific problem you must conduct an experiment , which a series of tests that you perform in order to solve your problem.
  • 4. Conducting Experiments
    • In order to conduct an experiment you must use the Scientific Method .
    • The scientific method is a series of steps taken during an experiment.
    • • There are four stages of the scientific method:
    • Prepare
    • Plan
    • Do
    • Conclude and apply
  • 5. Scientific Method
    • 1) Prepare :
    • - First Identify the problem (what you want to solve).
    • Next form a hypothesis . What's a hypothesis ?
    • A hypothesis is a statement that can be tested about a problem. (Why you think this problem exists).
    • Lets think of some problems and hypothesis's.
  • 6. Scientific Method (continued)
    • 2) Plan :
    • Here we design an experiment in order to test our hypothesis.
    • 3) Do :
    • Test our hypothesis & Observe and record the results of our experiment.
    • 4) Conclude and Apply :
    • Analyze our results (why our results occurred)
    • &
    • Draw conclusions (what can say about our experiment. Did it work? Why, Did it fail? Why?
    • And if so, what can we do next time to make it work?
  • 7. Important things to consider when using the scientific method
    • Trials, variables, and Data Tables
    • Trials are repeated experiments, performed in order to make sure that your results are consistent. (the more trials you perform the truer the results.)
    • Why else would you perform more than just one trial?
    • -Human error, faulty material
  • 8.
    • Variables are factors in an experiment that can change. (Watering plants)
    • Data Tables- these organize your observations and results into columns and rows.
    • We make data tables in order to keep track of results and be able to communicate them to others.
