    Revision of Scientific Method Revision of Scientific Method Presentation Transcript

    • mastrianascience.wikispaces.com
    • 1 Background information
    • Using the Internet ● Books (library) ● Specialists in that field ● to answer some questions before you start. www.dkit.ie
    • 2 Aim Hypothesis Engineering goal Investigative question
    • How do I pick 1ne? www.wix.com
    • Aim Classroom experiments “To...” Proving a known fact
    • Hypothesis Used with I.Q. and E.G. If the independent variable does this, then the dependent variable will do that.
    • Engineering goal Stating why you built something.
    • Investigative question Asking about the relationship between variables: What is the relationship between the independent variable and dependent variable?
    • 3 Method
    • What do we do to construct a method ? science.howstuffworks.com
    • Identify the variables.
    • Identify the equipment used, and describe HOW it will be used.
    • Step-by-step instructions on how the experiment runs.
    • All information in point form.
    • 4 Results
    • bschool.careers360.com
    • Table All data is tabulated in the course of the experiment. Independent variable (unit) No units next to values Dependent variable (unit) No units next to values
    • Y-axis Dependent variable Units 0 at the bottom, maximum value at the top. Graph A heading should indicate the relationship between the independent and the dependent variables. Always use clear indicators Connect the indicators using the line of best fit X-axis Independent variable Units 0 far left, maximum value far right
    • Analysis Discuss (point form): Relationship of variables Outliers
    • 5 Conclusion
    • paulmihalescu.com
    • In point form: Evaluate your hypothesis Explain relationship between Variables Chemistry: Provide balanced equations
    • 6 Bibliography acknowledgements

    • 1 2 types of proportionality
    • Direct Proportion
    • Inverse Proportion
    • Simple Proportion
    • Direct Inverse x y k = y/x x y k 400 40 0,1k 60 30 1800 300 30 0,1k 75 24 1800 200 20 0,1k 90 20 1800 50 5 0,1k 120 15 1800 yαx k(constant) = y/x Always a straight line through the origin. 1 y α /x k(constant) = xy y-x graph = hyperbole y-1/x2 = straight line
    • Square Proportion
    • Direct Inverse x2 y k = y/x2 x x2 y k = yx2 2 4 1 0,25 3 9 2,25 0,25 1 1 10 10 4 16 4 0,25 2 4 2,5 10 5 25 6,25 0,25 4 16 0,625 10 5 25 0,4 10 x 2 yαx k(constant) = y/x y-x graph = parabola y-x2 graph = straight line through origin. 2 1 y α /x2 k(constant) = x2y y-x graph = hyperbole y-1/x2 = straight line
