      How it works in the JC is it's worth 10 marks each ( 5x2)

      However you must have 3 Spefic Variables like Person's Pulse Rate in Biology and Time of Oscliation in Phyiscs. Then you can do 2 Generic Variables like Same timer used.

      Our teacher says do 7 in total for each experiment, as the examiners will only give marks if it's mentioned in the Marking Scheme

      I did 6 and 5 Alex.

      Physics I have:

      Pendulum Length

      - Independent variable: Length of the string

      - Dependent variables: Time and oscillations

      - Controlled variables: Pendulum mass, angle of the swing and the number of oscillations

      Pendulum Mass

      - Independent variable: Mass of the pendulum

      - Dependent variables: Time and oscillations

      - Controlled variables: Length of the string, angle of the swing and the number of oscillations

      Biology I have (5):

      - Independent variable: Duration of exercise

      - Dependent variable: Pulse rate

      - Controlled variables: Types of exercise, method of measuring the pulse and how often the pulse is measured
