Practical requirements
Measure reliably and prepare for the six practical-work groups: measurement, density, free fall, forces, thermal transfer and resistance.
Learning goals
- Measurements of length, mass, temperature, time interval, volume of liquids/solids and force (e.g. weight) using appropriate instruments
- Determination of the density of a liquid, or of a regularly or irregularly shaped solid that sinks in water
- Determination of the value of the acceleration of free fall
- Investigation of the effects of balanced and unbalanced forces
- Investigation of the factors affecting transfer of energy by thermal processes
- Determination of the resistance of a circuit component
