It is simple enough to make an interesting activity for a class and, if it is as successful as Sheldrake predicts it will be, this will be quite an exciting activity. There are a number of alternative methods to gathering the data discussed on the website, so I suggest you visit if you are interested in this. We will gather data on this through an experiment called the Ruler Drop. One method of doing the Ruler Drop is given below, but the students should determine for themselves how the experiment should be designed to ensure reliability and validity of results. E drops ruler.
S grabs it.
The smaller the number, the faster the reflexes. Repeat 20 times. Before you begin, agree as a class on the conditions of the experiment so the results are fair and unbiased. E shouldn't try to 'trick' S by pretending to drop the ruler first. For each subject, do the experiment a few times without recording the result to establish a fair procedure.
