Practical requirements
Learn the G1 measurement skills used across Science: select suitable instruments, determine average speed and use a multimeter correctly.
Learning goals
- Measurements of length, mass, temperature, time interval, volume of liquids/solids and force (e.g. weight) using appropriate instruments
- Determination of average speed of an object
- Measurements of current, voltage and resistance using multimeter
G1 Science · Practical skills
Start with the practical-skills lesson. Work through measurement, average speed and multimeter use in order, then try the course check. You show practical skill by taking real measurements safely and recording them clearly.

Use G1 situations to find the next practical skill to strengthen.
What to remember
- Match the instrument and its range to the quantity being measured.
- Read a scale from the correct position and record every value with its unit.
- Repeat a measurement when readings may vary, then calculate a sensible average.
- Find average speed from total distance divided by total time.
- Measure current in series, voltage in parallel and resistance only with external power removed.
Topic and syllabus information
These are the three Physics-related practical skills named for G1 Science K123 (2027).
Online questions can check your decisions, but hands-on work shows that you can use the apparatus safely and record real measurements.
