Paper 5
Ques%on 1 – Planning (15 Marks)
Skill Wordings MA
Defining the Problem (2)
Independent Variable __ is the independent variable or vary __ 1
what you change in the experiment each setup, only one per experiment
Dependent Variable __ is the dependent variable or measure __
what you measure as a result of what you varied in the ind. variable, usually involve a calc/measurement
Controlled Variables keep ________ constant 1
what you keep constant, could be more than one quanBty (typically not including constant values)
Methods of Data Collec%on (4)
Labelled Diagram* Use of circuit diagrams, drawing based on given diagrams, etc. 2
Draw a diagram with a setup that includes the devices you need, label all apparatus and physical quanBBes Label all possible apparatus.
used. (e.g. if dependent variable is current, then draw an ammeter) Include apparatuses that will measure your dependent variable.
WriLen Instruc%ons/Measurements* Use _______ to Determine/Measure ______ 2
Write instrucBons on how to use the apparatus in your diagram to measure or determine the quanBBes you Apparatus: electronic balance, LDRs, volt/ammeter, rulers, etc.
want to find. (e.g. if finding area, find radius and use 𝐴 = 𝜋𝑟 ! ) Include instruc%ons on how to measure your dependent variable
Methods of Analysis (3)
PloPng Graph Plot a graph of (log/ln) ____ against (log/ln) ____ 1
Plot a graph between in/dependent variables. Typically a st. line graph. Use of logarithms maybe required.
Rela%onship RelaGonship is valid if ______________ 0-1^
To show that how the two variables (asked by the quesBon) are related. (e.g. st. line passing through origin/ +ve/-ve gradient)
Finding Values _____ (constants) = variaGons of gradient or y-intercept 1-2
determine how the graph can be used to find the constants asked by the quesBon. Use variaGons of gradient/y-int to find _____ (constants)
Addi%onal Details (6)
Keeping Constants* • Keeping mass/weight/length/width/intensity/field…etc constant Max. 6
The goal is to minimise variaBon due to other factors – think about other quanBBes presented that is • Use idenGcal tools (metal
neither controlled, independent nor dependent, this should be included in your methods of data collecBon sheets/rulers/wires/screen/springs…etc)
Addi%onal Details* • Use of clamps, rulers with set squares to keep things in place.
this should be included in your methods of data collecBon • AddiGonal apparatus used: electronic balance, volt/ammeter, etc
Validity and Accuracy of Experiment* • Repeat experiment, find (measurement of) ___ and take average
this should be included in your methods of data collecBon • Use of apparatus w/ higher degree of accuracy, e.g. micrometre
Safety Precau%ons* • Using insula%ng gloves, avoiding touching metal parts, etc.
this should be included in your methods of data collecBon • Wear safety goggles, Ge hair up, etc.
*N.B. The measurements or instrucBons used for the independent/dependent variables should also be carefully planned to maintain accuracy and validity, which might include keeping
constants, addiBonal details, any precauBons.
^The mark can be awarded as part of the addiBonal detail secBon.
