Your work on pearl pendulum has been received and everything looks very good, except that one bit of information seems inconsistent.
The bracket is only about 10 cm high, while you reported pendulum length 18 cm (180 mm). The times you reported are consistent with a pendulum about half that length. Is it possible you made an error in measuring the length?
Please let me know if you have any questions related to this orientation assignment.
The pendulum was not properly erected so I used my imagination to fix the problem. Also, the pearl that was supposed to be glued on was broken off, but I think I fixed it so that it will work.
The sounds get further apart. There was an obvious amount of time between strikes that got furtnher apart as the pearl began to stop.
The sound gets closer together. It is obvious to hear the pearl striking the metal faster and faster until it stops.
I put a peice of copy paper under the pearl end of the bracket and tested the rhythm about 10 times and came up with an average of 18 times that it hit the bracket.
With the bracket parallel to the side it sounded like it was getting closer together.
With the bracket rotated 45 degrees counterclockwise it doesn't sound as fast as the first time.
With the pendulum now rotated 90 degrees from its original position it sounds like it is constant.
With the pendulum rotated 135 degrees from its original position it sounds like it is getting slower.
With the pendulum rotated 180 degrees from its original position it gets slower again. With the pendulum rotated to 225 degrees from its original location the sound speeds up in the beginning but slows down before it stops completely.
With the pendulum rotated 270 degrees from its original postion it sounds like it is constant. With the bracket turned 315 degrees from the original location the sound gets closer together again.
You would turn the bracket to either 90 degrees or 270 degrees from the original location to obtain the most regular 'beat'.

With the pendulum pulled back tauntly it was released and hit the bracket and then bounced back.
The pendulum did not bounce back as far as the first release
Still yet it is not bouncing back as far because it is coming closer to a stop.
the motion between the second and first hit bounces farther than the fourth and sixth hit because the latter is closer to stopping.
It is moving quicker because it has more momentum.
The subsequent time intervals would decrease.
The experiment provides evidence against the hypothesis that the length of the pendulum's swing depends only on its length and is independent of how far it actually swings because no matter how long or short the string is the pendulum can only bounce as far as the string will allow thus making the length of the swing and how far it actually swings depedent of one another.
