Method
Your method should be a step by step recipe of what you have done to carry out your experiment. Another person, who has never done any science, should be able to pick up your method and carry out your experiment in exactly the same way.
Below is an example. In this experiment the pupil is trying to find the relationship between the surface area of a beaker and the amount of water that evaporates.

Bad MethodPut water in a beaker and leave it on the windowsill Record how much has evaporated after a week.

Good MethodUsing a measuring cylinder, pour 100ml of water into four beakers: a 100ml beaker, a 200ml beaker, a 250ml beaker and a 500ml beaker.
Calculate the surface area of the beakers by measuring their diameter with a ruler and using the formula for the area of a circle: area= pi x diameter Leave all four beakers on the same windowsill for a week. At the end of the week, measure the volume left in each of the four beakers using the measuring cylinder. Calculate the volume of water that has evaporated using the formula: Evaporated volume = 100ml - volume after a week Plot your results on a graph of Evaporated volume against surface area. |
