Each of the statements in the top box is an example of one of the processes of carrying out a fair test. We use the saying "Cows Moo Softly" to remind us of the three key processes. "Cows" is used to remind us of the term "change"- there is one thing that is different between two situations in the investigation- one thing that is changed. "Moo" is to remind us that for a scientific investigation items need to be measured so that the results can be obtained. "Softly" reminds us that in a scientific investigation some things that have to be kept the same to ensure that test is fair. Drag and drop the example associated with each process to the correct position.
