The hypothesis is that persons who have been practising yoga will have reduced blood pressure.

You will divide the participants into two groups and measure their blood pressure with a portable wrist blood pressure monitor. The first group will watch television for two hours and the second group will practice yoga for two hours.

You will need a yoga instructor, a television set, 20 male participants between the ages of 35 and 45, and a portable wrist blood pressure monitor.

The results of the experiment showed that the participants in the yoga group had a decline in their blood pressure after a few days, while the participants in the television group had a slight increase in their blood pressure. This proves that the hypothesis that persons who have been practising yoga will have reduced blood pressure is true.

This science project is interesting because it shows how yoga can be used to reduce blood pressure, which is a common health issue.

Variations of this experiment could include different age groups or female participants, or comparing the blood pressure with other activities like listening to soft music, aroma therapy or practicing tai chi.
