=__//**Caffeine Rush**//__= = = =Question-= How does caffeine in different drinks affect blood pressure and heart rate?

=Hypothesis-= If the amount of caffeine in one serving of a caffeinated drink goes up, then the drinkers blood pressure and heart rate will go up.

=**Science Fair Procedure**=

1. The human subjects will not take much caffeine throughout the day. 2. At 5:00 p.m. I will start the experiment. 3. Check each human subject's blood pressure on the left arm before they drink the caffeine and record it. 4. Measure out one serving of Five Hour Energy for each person in a graduated cylinder and pour each serving into different cups. 5. Each human subject drinks one cup of the substance completely. 6. During the next thirty minutes, the human subjects will do light activity. 7. Thirty minutes after the human subjects drank the substance, their blood pressure will be measured on the left arm again and recorded. 8. Repeat steps 1-7 for a total of seven straight days. 9. Repeat steps 1-8 for the other substances (Vault, Monster, and Coffee) in different seven day spans.

=**Materials**=

Human subjects Automatic blood pressure monitor Stopwatch Measuring Cup Drinking cups Pencil and Paper (to record data) Five Hour Energy Monster Vault Diet Mountain Dew

=Data and Observations=

I already have the measuring cup, stopwatch, drinking cups, and pencil and paper.

10/10/10- Bought an automatic blood pressure monitor

10/21/10- Talked with Mrs. Wilson and made some changes to my procedure. Instead of testing a few people with many trials per person, per drink, I will use ten people and do one trial per person, per drink.

=Procedure #2= 1. The human subjects will not take much caffeine throughout the day. 2. At around 3:00 p.m. (may change due to situation) I will start the experiment. 3. Check each human subject's blood pressure on the left arm before they drink the caffeine and record it. 4. Measure out one serving of Diet Mountain Dew for each person (may need graduated Cylinder) and pour each serving into different cups. 5. Each human subject drinks one cup of the substance completely. 6. During the next thirty minutes, the human subjects will do light activity. 7. Thirty minutes after the human subjects drank the substance, their blood pressure will be measured on the left arm again and recorded. 8. Repeat steps 1-7 for the other substances (Vault, Monster, and Five Hour Energy) in different weeks (usually on Friday).

10/22/10- Finalized the drinks I will use and changed coffee to Diet Mountain Dew to please all ten of my human subjects. Made list of all my possible human subjects and asked if they would participate the next few days.

10/23/10- Got the Vault

10/ 22-26/10- Finalized the list of human subjects I will use and made sure they knew the dates of testing, the risks of experiment, drinks they will have to drink, and checked with their parents if they are a student.

10/26/10- Got the Diet Mountain Dew

10/28/10- It was decided by my qualified scientist, Cheryl pardoe, that one of my human subjects should drop out due to health reasons. To get a replacement I called someone else to ask if they would participate and they agreed to participate.

10/29/20- After school at 3:00 p.m. all my participants, met except for two, meet in the student commons and my designated supervisor came in with all my materials. My participants completed steps 1-7 in the New Science Fair Procedure for Diet Mountain Dew. When my dad got home from work I completed steps 1-7 in the Procedure #2 for Diet Mountain Dew for him. The other Participate could not make it and will do it another day.

11/5/10 After school at 3:00 p.m. all my participants, except my dad who did it later, meet in the commons with my designated supervisor and materials. My participants completed steps 1-7 in the Procedure #2 for Vault. The one participant who missed the first day make up his Diet Mountain Dew and will be a week behind the others. Due to time my dad could not do it and will make it up another day.

11/7/10- Got the Monster

11/8/10- My dad make up his Vault test today when he got home.

11/10/10- After School, the Participant that was a week behind came came over to my house to complete the Vault test so he would be back on schedule. Also, my mom did the Monster test because Friday would not work out with her schedule. Each participant completed steps I-7 in the Procedure #2 for their respective Substances.

11/12/10- After school, at 3:00 p.m., all my participants, except my dad, meet in the commons with my supplies and my designated supervisor. They completed steps 1-7 in the for Monster except my Mom who did it two days earlier. Due to time restraints my dad will complete the Monster test on another day.

11/15/10- My dad make up the Monster test when he got home from work and bought the 5 Hour Energy.

11/19/10- After school at 3:00 p.m, All my participants, except for two, meet in the commons with my designated supervisor and materials. They completed their final steps 1-7 in Procedure #2 for 5 Hour Energy. Once all the testing was done we got pizzas and sodas for the participants to thank them for giving up their time to do my science fair project. The last two participants that could not be there will make it up it together another day.
