Does caffeine affect your memory

• Does caffeine effected boys or girls more?
• In my tests, it seems to help remember the items
  in the box.

Research

• The caffeine soda that I used in my investigation
  was Mt. Dew. It is made by Pepsi and it contains
  for every 8 oz, 110 calories, 40 mg of sodium
  (salt), 31 g of carbohydrates, and 36 mg of
  caffeine. Some of the ingredients in Mt. Dew are
  water, high fructose corn syrup, orange juice,
  and other ingredients. My research into caffeine
  tells me that the chemical name is
  1,3,7-trimethylxanthine and has its formula is
  C8H10N4O2. Which are Carbon, Hydrogen, Nitrogen,
  and Oxygen. 10 grams of caffeine will kill you.
  You would have to drink 2,400 oz (300 cups) of
  Mt. Dew to be poisoned. Nine out of ten
  Americans drink caffeine every day, either in
  coffee or pop. Caffeine works in your brain. It
  slows down the chemical that causes you to be
  sleepy. This keeps your brain awake. It also
  increases dopamine and makes you happier and in a
  better mood. Some facts on the human brain
  include that it weighs about three pounds. A
  cats brain weighs only 2 of the human brain.
  The brain also has 100,000,000,000 (100 Billion)
  neurons.

Procedure

• Procedure
• select the 6 boys and 6 girls to participate
• have the boys look in the box for 1 minute
• cover the box
• have the boys write down the items on paper
• give them a cup of Mt. Dew
• wait 2 minutes
• show them the box again
• time them 1 minute
• cover the box
• list the items in the box
• repeat steps with the girls

8
Variables

• Independent-the boys and the girls
• Dependent-the items listed by the boys and the
  girls before and after drinking the Mt. Dew
• Control-same amount of time, same items, same
  amount of Mt. Dew

Results

• My hypothesis was correct. The boys remembered
  more items than the girls after they drank the
  Mt. Dew. The boys remembered more items by 24
  with the caffeine, and the girls remembered 18
  more items. Two girls showed no change in the
  number of items remembered, but no one had fewer
  items than without the caffeine.
