GCSE SCIENCE COURSEWORK ISA P1 P2 P3 ISA 25%

ISA takes 3 lessons: Lesson 1: planning, practise with apparatus, choose independent variable, choose range, take a few trial readings DISCUSSION DRAW UP BLANK HEADED TABLE (2 marks) Lesson 2: take main results PLOT GRAPH (4 marks) Lesson 3: do ISA paper (28 marks)

ISA 1 : variables What is the dependent variable? What could be the independent variable? What variables should be controlled? Are there any discrete / categoric variables?

ISA 2: measuring What will you measure? What measuring device will you use? How will you make your measurements more reliable?

ISA 3 can you explain these terms: Anomaly Zero error Accurate result Precise scale

ISA 4 WHAT ABOUT THESE TERMS? Random error Systematic error Calibrate (eg. how would you calibrate a Newton Meter?
