Title
  • This is not a separate slide, but the title is
    VERY IMPORTANT. Its the first thing people will
    read when they see your board. The title should
    be a shortened version of your investigative
    question. You can be creative here as long as
    your title still reflects the projects purpose.
    Follow all rules for capitalization in titles.
  • Examples
  • Comparing Compost
  • What Color of Light is Important for
    Photosynthesis?
  • The Effect of Sail Material on the Speed of a
    Sail Car

Abstract
  • Example
  • Abstract
  • Advertisers are always touting more powerful
    and longer lasting batteries, but which batteries
    really do last longer, and is battery life
    impacted by the speed of the current drain? This
    project looks at which AA battery maintains its
    voltage for the longest period of time in low,
    medium, and high current drain devices. The
    batteries were tested in a CD player (low drain
    device), a flashlight (medium drain device), and
    a camera flash (high drain device) by measuring
    the battery voltage (dependent variable) at
    different time intervals (independent variable)
    for each of the battery types in each of the
    devices. My hypothesis was that Energizer would
    last the longest in all of the devices tested.
    The experimental results supported my hypothesis
    by showing that the Energizer performs with
    increasing superiority, the higher the current
    drain of the device. The experiment also showed
    that the heavy-duty non-alkaline batteries do not
    maintain their voltage as long as either alkaline
    battery at any level of current drain.

Question
  • Example Which is the best cleaning agent for
    removing stains? I chose this project because
    many commercial cleaners are expensive and
    harmful to the environment, and I wanted to
    explore a cheaper, safer alternative that was
    equally effective at removing stains.

Hypothesis
  • Example If I stain cotton cloth with various
    substances and try multiple cleaning agents to
    remove the stains, then I predict that a mixture
    of vinegar and baking soda will be most effective
    in removing the stains. In researching this
    topic, I found that mixing vinegar and baking
    soda produces carbonic acid, which I think will
    break down stains.

  • Example
  • Mustard
  • Blueberry syrup
  • Ketchup
  • Prune juice
  • Water
  • Vinegar
  • Baking soda
  • Commercial pre-stain treatment
  • Commercial laundry detergent
  • Q-tips
  • Watch/timer
  • Plastic cups for washing fabric swatches
  • 100 cotton fabric swatches (approximately 3 inch
    squares)
  • Permanent marker for labeling

Procedure (example)
  • Procedure
  • Cut at least 28 pieces of 100 cotton fabric into
    approximately 3 inch squares.
  • Use a permanent marker to label each of the
    fabric pieces using all of the
  • combinations of stain and detergent mixture
    (stains ketchup, mustard, blueberry syrup,
    prune juice detergent mixtures water, vinegar,
    vinegar and baking soda, commercial
    pre-treatment, commercial laundry detergent,
    vinegar and baking soda paste laundry
    detergent, commercial pre-treatment laundry
    detergent).
  • 3. Place a stain on each sample according to the
    labels.
  • W water (50mL)
  • V vinegar (50mL)
  • Vbs vinegar baking soda solution (30mL
    vinegar/20mL baking soda)
  • cpstw commercial pre-stain treatment water
  • (20mL commercial pre-stain treatment 30mLwater)
  • ld laundry detergent water (20mL laundry
    detergent 30mL water)
  • vbp ld vinegar, baking soda paste laundry
    detergent
  • (10mL vinegar 40mL baking soda) (20mL laundry
    detergent 30mL water)
  • cpst ld commercial pre-stain treatment
    laundry detergent
  • (20mL commercial pre-stain treatment 30mLwater)
    (20mL laundry detergent 30mL water)
  • Place each sample in the detergent mixture and
    scrub for 2 minutes.
  • Remove excess liquid and compare the samples when
    they are dry.

    no change, 1 worse

Results
  • Example
  • Results
  • The results show that the best way to remove
    stains is to use either a combination of vinegar
    and baking soda paste commercial laundry
    detergent or to use a combination of commercial
    pre-stain treatment laundry detergent. Both of
    these treatments scored a mean average of 4.75 on
    the effectiveness scale (5 being the most
    effective).
  • My hypothesis was only partly accurate. I
    thought that just washing the stain in a vinegar
    and baking soda solution would be enough to
    remove the stain. What I found was that using
    more baking soda to make vinegar and baking soda
    paste then combining it with laundry detergent
    was the best way to remove most stains. This even
    worked better than using the laundry detergent
    alone or the commercial pre-stain treatment
    alone.
  • Since the commercial pre-stain treatment
    combined with laundry detergent did not appear to
    remove stains any more effectively than the
    homemade vinegar and baking soda paste laundry
    detergent, I would recommend people purchase
    baking soda and vinegar since it is the cheaper
    and more eco friendly product.

Conclusion
  • Conclusion
  • My hypothesis was that Energizer would last the
    longest in all of the devices tested. My results
    do support my hypothesis.
  • I think the tests I did went smoothly and I had
    no problems, except for the fact that the
    batteries recover some of their voltage if they
    are not running in something. Therefore, I had to
    take the measurements quickly.
  • An interesting future study might involve
    testing the batteries at different temperatures
    to simulate actual usage in very cold or very hot
    conditions.

Future Considerations
  • Future Considerations
  • Tell what variable you would change if you could
    do the experiment again.
  • Include any problems you encountered while
    conducting your experiment.
  • Include any unintended results you may have
    discovered, which may lead to subsequent
    experiments.
