Physical Science Grade 12 Latest Experiments and Memos for CAPS Curriculum (Syllabus) South Africa: A National Curriculum and Assessment Policy Statement (CAPS) is a single, comprehensive, and concise policy document introduced by the Department of Basic Education for all the subjects listed in the National Curriculum Statement for Grades R – 12. CAPS gives detailed guidance for teachers on what they should teach and how to assess.
On this page you will find Physical Science Grade 12 Experiments and Memos for Term 1, Term 2, Term 3, and Term 4.
Practical Experiments and Activities
Term 1:
- Chemistry Experiment: The preparation of esters and smell identification
- Marks: 15% of annual SBA
Esters have a very fruity smell. Naturally occurring esters are found in fruits. Esters can be synthesised by the reaction of a carboxylic acid and an alcohol. This reaction is known as esterification. This reaction can be catalysed by concentrated sulphuric acid.
AIM: Produce different esters by using a range of carboxylic acids and alcohols. Identify the esters formed by their smell.

Term 2:
Chemistry Experiment: How do you use the titration of oxalic acid against sodium hydroxide to determine the concentration of the sodium hydroxide?
OR
Physics Experiment: The conservation of linear momentum
The momentum of an object is determined by two variables, namely mass and velocity. Linear momentum (momentum in a straight line) can be defined as the product of mass and velocity.
The verification of the conservation of momentum can be determined experimentally during an explosion and a collision.
AIM
To verify the conservation of linear momentum during a simulated explosion.
Marks: 15% of annual SBA
Term 3:
Physics Experiment:
- Part 1: Determine the internal resistance of a battery.
- Part 2: Set up a series-parallel network with a known resistor. Determine the equivalent resistance using an ammeter and a voltmeter and compare it with the theoretical value.
The term ‘lost volts’ refers to the difference between the emf and the terminal voltage. The voltage is not ‘lost’. It is the voltage across the internal resistance of the battery, but ‘lost’ for use in the external circuit.
The internal resistance of the battery can be treated just like another resistor in series in the circuit. The sum of the voltages across the external circuit plus the voltage across the internal resistance is equal to the emf
