    I don't know what does the biology experiment about the increase of exercise on the heart is about. what exactly is this experiment suppose to show? thanks

      basically similar to experiment for heart rate and breathing in the biology course. it is to show that through exercise the heart rate/pulse increases. you take rate first and after exercise. very nice experiment.

      ok thanks so much. I did it in school and I counted my pulse rate and it was in the high 100s. my teacher says im not doing it right. do you know what im doing wrong?

      it depends on where you are taking your pulse. if it is your wrist make sure you use you index and middle finger. count for a minute - get someone else to time you so you can concentrate and not try to watch the clock. get your average of 3.

      you could just naturally have a high pulse rate but the rate is faster in young children, athletes and sometimes women.

      ask your teacher to take it too or a parent.

      Sorry, TrionaM, but NEVER take your pulse for a minute, as in the course of that minute the rate will change. Always take it for 15 seconds and then times by 4.

      @bridgetown1 It's easier and probably more accurate to take it for 6 seconds then multiply by 10.

      For the Physics, pendulum experiment, Do you know of any good sites or books for the background research?

      Sorry I did the Chemistry. but it is in the leaving cert book I think and you can always youtube it for examples- but explain how you adapted it if you did.
