    6.1 Scientific Method 6.1 Scientific Method Presentation Transcript

    • SCIENCE PROCESS SKILLS PP. 4-8 ALSO P. 646-647 REVIEW THESE TERMS HYPOTHESIS OBSERVATIONS DATA INDEPENDENT VARIABLE (0R MANIPULATED) DEPENDENT VARIABLE (OR RESPONDING) CONSTANT INFERENCES
    • HYPOTHESIS
      • AN EDUCATED GUESS OR THE PREDICTION THAT IS BASED ON YOUR OBSERVATION
      • CAUSE AND EFFECT RELATIONSHIPS
      • A SPECIAL PREDICTION THAT FORECASTS HOW THE INDEPENDENT VARIABLE WILL AFFECT THE DEPENDENT VARIABLE
      • IF, THEN, STATEMENT
    • YOU TRY IT!
      • WRITE A HYPOTHESIS FOR THE FOLLOWING EXPERIMENT:
      • JOHN WANTS TO KNOW IF THE SIZE OF THE PAPER AIRPLANE’S WINGS WILL CHANGE THE DISTANCE THAT THE PLANE WILL FLY.
    • First, identify the independent variable.
      • What is the independent variable:
      • The size of the paper airplane’s wings
      • Now identify the dependent variable:
      • The distance the plane will fly is the dependent
      • variable.
    • What is your hypothesis?
      • Write your hypothesis.
      • If the size of the paper airplane’s wings increase, then the distance the plane flies will increase.
    • WHAT DO I ALREADY KNOW?
      • HAVE STUDENTS COMPLETE THE WARM UP SCIENTIFIC INQUIRY
      • PART 1
        • PUT THE STEPS OF THE SCIENTIFIC METHOD IN PROPER ORDER.
      • PART 2
        • MATCH THE FOLLOWING TERMS IN THE CORRECT ORDER.
    • MATCH Reread pp 4-8
      • HYPOTHESIS
      • CONTROL
      • VARIABLE
      • EXPERMENT
      • CONCLUSION
      • THEORY
      • DATA
    • INFERENCES
      • An inference is an explanation for what we have observed. It explains what might be happening.
      • An inference must be logical.
      • Inferences can be changed as you get more information.
    • What inference can you make?
      • You come into the classroom and you observe someone’s books are on your desk.
      • What inference can you make?
    • Variables
      • The part that changes in an experiment is called a variable .
      • Independent variable is what the scientist or you change in an experiment.
      • Dependent variable is the difference the scientist or you measure after making the change.
      • A Constant variable is what the scientist make sure stays the same so the experiment is a fair test.
    • You Try It!
      • Jan counted the leaves on each of three plants. Then she put one plant under a blue light bulb, another plant under a yellow light bulb, and a third plant under a white light bulb. She kept all three lights on from 6:00 a.m. to 9:00 p.m. After 2 months, she counted how many leaves each plant had.
      • Name the independent variable, the dependent variable and the constant
    • Check your answers!
      • Independent Variable: the color of the light
      • Dependent Variable: the number of leaves on the plant.
      • Constants: could be the kind of plants, the soil in the plant, the amount of water, the pot size, temperature, the wattage of the light bulb, or
      • the distance the light is from the plant.
    • HERE IS AN EXPERIMENT TO TRY FOLLOW THE PROCEDURE MATERIALS:
      • TRY THIS WITH YOUR CLASSMATE OR PARTNER
      • OBTAIN TWO COINS, A PENNY AND A QUARTER.
      • A CONTAINER OF WATER ( A BEAKER)
      • TWO EYE DROPPERS
    • Write a Hypothesis about your science experiment with the penny and quarter.
      • Hypothesis:
      • What is the independent variable?
      • What is the dependent variable?
    •  
    • Warm-up
      • Read the article on Methane Found in Mars
      • Atmosphere
      • Make a hypothesis about this article. Write your hypothesis at the bottom of your article.
    • WRITE YOUR HYPOTHESIS FOR YOUR EXPERIMENT
      • IDENTIFY YOUR INDEPENDENT VARIABLE AND YOUR DEPENDENT VARIABLE
      • WHAT ARE TWO CONSTANT VARIABLES?
