               1.13.a   Measuring forces with a dynamometer :     ( 10 points ).

         MALIEK’S WORK ( Click here and download a pdf with your work for today Monday ).

      You already know that forces are measured in NEWTONS. But today we are using the appropriate device to measure forces, like weight, using the DYNAMOMETER. It is like a spring with a scale given in newtons in which we can measure different objects’ weights. The more the object weights the more the spring inside stretches and more newtons are given onto the scale.

                                                         1.13.a.1  Data table for dynamometers. ( 10 points ).


                  Students use different kinds of dynamometers to weight several different amount of objects with different weights. They have dynamometers in grams, in newtons and in kilograms at their reach. Once they weight the same objects as much in grams as in newtons they take notes about them at the paper given. They get used to read the different scales dynamometers show.

( Maliek, whatch the video in 1.13.a.3 and do the summarize or outline about it. Do nothing else ).

                                                       1.13.a.2   Dynamometer marble’s weight.   ( 5 points ).

                                                       1.13.a.3   DYNAMOMETER VIDEO.

                                                                                                                     ( 9/20/17   Wednesday )

           MALIEK’S WORK   (Click here and download a pdf with your work for today Wednesday ).

                       Please Maliek, read the pdf with the text about Hooke’s law and do a little summarize of it at your workbook. After that look up for information about who Robert Hooke was and did because he is the scientist who did the Hooke’s law in 1660.

   +  INFORMATION ABOUT HOOKE’S LAW AND DYNAMOMETERS :   Copy the following information about Hooke’s law  given in PICTURE 1 at your workbook :


                                                                            PICTURE 1

                                                                            PICTURE 2

                                                   1.13.a.4    WHAT A DYNAMOMETER IS.   ( 5 points ).

                                                      1.13.a.5    Dynamometer’s parts and quiz.  ( 5 points ). 

                                                                                                                     ( 9/21/17  Thursday )

 - 1.14  Could you explain maybe now the HOOKE’S LAW and what it is used for ?.     Prepare and make up a GRAPH-POSTER about it now !!  ( Follow the instructions given by your teacher ).         ( 20 points ).

( Maliek, today read and do the following as your classmates do too ) :


  1- This is what you will learn today ( Read it ) :   Today you will be able to ...  ( 5 points ).


  2 - Write today targets in this paper given to you :   Write your targets for today.  ( 5 points ).
    ( In a paper like this you have to write the targets given below at the point number 3 ).

  3- These are the main targets pursuited today :      MAIN TARGETS
     ( Write these targets in the table given in point number 2 ).

  4- Make up the following graph to differentiate the parts of it :    Graph to build.  ( 5 points ).
      ( In a big paper or construction paper make and copy this graph and name the parts of it ).

  5- With the given data from the table make up and build the suitable graph :     ( 5 points ).

                                                                                                      Table with data for building a graph.


                                                                                                                         ( 9/22/17  Friday )

         1.15    We work today in the computer room 217. 

                    Follow the instructions given by your teacher in order to do your work at the computer.      ( 20 points ).


                   * First of all copy the following learning targets at your workbook in order to understand what you are going to learn today in class :

                                              LEARNING TARGETS FOR TODAY’S LESSON.

                       * Consult the following links in order to answer the following QUESTIONS :

                                                                         LINK 1

                                                                          LINK 4  ( Nice Hooke’s law simulator, try it!! )

   ( At this simulator you can try with different values of the spring constant K in order to make the spring thicker or thinner and make it stronger or weaker and check how much it stretches when a force is applied ).

                                                                          LINK 5

                                                       VIDEO 1 ABOUT ROBERT HOOKE.

                          VIDEO 2 ABOUT THE GENIUS ROBERT HOOKE ( Optional, at home ).

    - If you have enough more time do a powerpoint presentation telling about Hooke’s Law, what it is, what it represents, what it talks about springs, about the Hooke’s law graph, and talking something about who Robert Hooke was. A general presentation about the Hooke’s law issue.
