What teachers look for when assessing manipulation and measurement and observation, recording and reporting: setting up apparatus, reading instruments, safe working, tables, diagrams and clear written reports.
5 narrated scenes. Press play, listen and read along — the points appear as they are explained. Use ‹ Prev / Next › or the scene bar to jump to any scene.
Two-thirds of the SBA marks (60 of 90 for experimental skills) are for what you do with apparatus and how you record it, so good habits at the bench pay off.
Narration uses your device’s built-in voice. No sound? Switch to “Captions only” — the captions advance on their own.
Copy these into your notebook in your own words — that is how they stick.
Manipulation/Measurement: set up, use instruments correctly, work safely and efficiently. 30 raw marks.
Observation/Recording/Reporting: observations, tables, diagrams, written report. 30 raw marks.
Follow the diagram; apparatus secure; circuits correct.
Eye level; check zero; suitable range and sensitivity.
Hot liquids, mains, sharp objects, glass.
Quantity and unit in each heading; consistent decimal places.
Title, aim, diagram, method, results, conclusion.
Repeat and average; check zeros.

8 items modelled on real CSEC Paper 1 questions. Choose one answer for each, then check. Aim for 80% or better. Work each item on paper first.
Write full answers, then reveal the mark scheme and tick the points you earned (14 marks in total). Show all your working — method marks count. Your answers are saved on this device.
Question 1 [14 marks]
A student measures the period of a pendulum for different lengths, using a metre rule and a stopwatch.
(a) (a) State the instrument, and its precision, that should be used to measure the length. [2]
(b) (b) State two ways to measure the time for a period more accurately. [2]
(c) (c) Draw a table with headings and units for the results. [4]
(d) (d) State two features of good practice in writing the report. [2]
(e) (e) State two safety precautions in a laboratory practical. [2]
(f) (f) Explain why the student should check the zero of an instrument. [2]
Everything in this lesson is based on these parts of the CXC syllabus and papers.
