Study focus - 3 things
- Good lab work records measurements clearly with headings, units, and sensible precision
- A lab write-up usually includes aim, apparatus, method, results, and conclusion
- Tables should make results easy to read and compare
Section 1Lab measurements
Measurements should be recorded as soon as you take them. Include units every time, either in the table heading or beside the value. Watch out: a neat table with missing units can still lose marks.
Section 2Tables
A good results table has clear headings, units, and organised rows. Put the variable you change in one column and the variable you measure in another. Keep decimal places consistent where possible.
Section 3Write-up sections
A basic lab write-up includes aim, apparatus, method, results, and conclusion. The aim says what you are investigating. The method says what you did, and the conclusion explains what the results show.
Section 4Fair tests
A fair test changes one variable at a time and keeps other important conditions the same. For example, if Ardenne students test how ramp height affects toy-car speed, the car and surface should stay the same while height changes.
Examples
A table heading says 'Time' but gives no unit. What is missing?
The unit is missing. It should say something like Time / s or Time (s).
A class tests whether ramp height affects toy-car speed. They change the height but use the same toy car and same floor each time. Why is that good method?
It is a fair test because only one main variable, ramp height, is changed while other important conditions stay the same.
