    Graphing

     

    Part 1 about 30 mulitple choice

    Part 2 Graphing

    Part 3 Scientific Writing

     

    Vocabulary

    1.    Theory

    2.    Observation

    3.    Inference

    4.    Control Group

    5.    Experimental Group

    6.    Independent variable (manipulated variable)

    7.    Dependent variable (responding variable)

    8.    Hypothesis

    9.    Results

    10.              Conclusion

    Measurement

    Meter (Metric Ruler)   1m= 100cm= 1000 mm      1cm= 10mm

    Liter (Graduated Cylinder) read from the bottom of the meniscus

    Grams (Triple Beam Balance)

    Microscope Parts

    Know the parts of the microscope

    Diaphragm – adjustes the amount of light

     

    Know how to find total maginification:

    Objective lens X Eye piece (ocular lens) = Total magnification

    10                        X       10                           =

    5                         X        10                          =

     

    Graphing;

     


                       Dependent

                       Variable                       make sure you are using equal

                       Y axis                            number of spaces

                                                              Use numbers that are easy to work        

                                                      Think of money 1, 2, 5, 10, 20, 25, 100

     

     

                                                    Independent variable

                                                    X axis                 

     

    To make a relationship statement

    Look at your data table

    Independent variable           Dependent variable

    Water temperature

    Numbers of gas bubbles

    10

    20

    9

    30

    8

    40

    7

    50

    6

    What is the relationship between the temperature and the numbers of gas bubbles released?

    1)   Mark an appropriate scale on the 2 axes

    2)   Plot the data on the graph use a dot and surround with a circle
