Question ??
  • How does acid rain effect plant growth?

3
Hypothesis
  • Acid rain will cause plant growth to be slowed
    and stunted.

4
Experiment
  • Place 4 identical plants in glass pots and place
    them in a sunny place. Water two of the plants
    with regular tap water and the other two plants
    with an acidic solution (water/lemon juice), that
    has a pH equal to acid rain (below 5.6). Water
    the plants once a day. Use a spray bottle and
    spray a mist on the leaves as well. Observe the
    plants, their leaves, height, stem, roots, and
    flower of each plant. Record your observations
    on a chart. Repeat this procedure for 5 to 7
    days.

5
Conclusion
  • The data collected will support or not support
    the hypothesis. The data will provide
    information that will help to determine the
    effect of the growth as you compare the plants
    watered with regular tap water and plants watered
    with the acidic solution (water/lemon juice).
    The suspected outcome is that the plants being
    watered with the acidic solution will not grow as
    healthy as those being watered with regular tap
    water, or they will die.

Appropriate Grade Level
  • This experiment can be modified for any grade
    where the standards require the study of plants
    and their environments. This could include grade
    3, where the standards include Habitats and
    Adaptations--Explain how changes in the habitats
    of plants affect their survival. Acid rain
    changes the soil which is part of the plants
    habitat.

Falsifiable
  • This experiment is falsifiable and can be done in
    different way to see the effects of acidic
    solutions on plant growth.

10
Logic
This experiment is logical because it takes
water, sunlight, and soil for plants to grow into
healthy plants. Therefore acid rain, with a pH
of approximately 5.5-2.0, will be harmful to
plant life especially since most plants do not
like acidic soil. With more air pollution from
automobiles, acid rain will continue to be a
problem for us to deal with until we find ways to
improve our air quality.
11
Replicable
  • This experiment can be reproduced, so it would be
    replicable.

12
Sufficient
  • This experiment can produce significant data with
    observations being done on a daily basis for five
    to seven days. It can also be carried out for
    longer periods of time if more data is required.
