This lesson begins by pupils being provided with the aim of the investigation plus an equipment list, pupils will need to use this to decide what the independent, dependent and control variables of the practical may be. The next slide runs through some of the important details of the practical, using this pupils will then need to write a step-by-step method summarising how they are planning to conduct their investigation, they can work in groups to plan this but must complete their own worksheet.

Next, pupil will conduct the experiment to measure the effect of a distraction on student volunteers reaction time. Results should be collected using the worksheet provided, once they have collected their raw data they can use this (as well as the calculation provided) to work out the reaction time for each volunteer in each trial, and a mean can be calculated.

Once the second table of results on the calculated reaction times have been filled in pupils can complete their graph of results, this can then be used to write a conclusion using prompt questions provided on the plenary slide of the PowerPoint presentation.
