Quick Check
For each experiment check that you can do can do each of the following:
- Draw a fully labelled diagram which includes all essential apparatus (have you included the apparatus necessary to obtain values for both variables?)
- Be able to state how the two sets of values were obtained (this is a very common question)
- Describe what needs to be adjusted to give a new set of data
- Write down the relevant equation if there is one associated with the experiment
- Be able to state how the data in the table will need to be adjusted.
- Be able to list three sources of error/precautions
If the experiment involves a graph
- Know how the data provided will need to be adjusted
- Know what goes on each axis
- Know how to use the slope of the graph to obtain the desired answer
