1. Choose a sport (I have chose football)

a. Search for the record performances in that sport across time (e.g. the records for the sport in the 1930's, 1950's, 1970's, 1990's and today.)

1. How have records changed

2. Did they change significantly more during one period of time than during others?

3. What may have cause this more significant change in this sport?

4. Why do you think performances are better now than they were in previous decades(e.g. new techniques, technological advances, diet changes)?

b. Now search for records performance times across ages (e.g. 20s, 30s. 40s, 50, 60s, 70s.) Graph the performance changes across these ages. Discuss your findings
