Performance Task:

|
|
Scientists often use the process of scientific
inquiry to investigate cause and effect relationships. In recent years, our
environment has been the focus of such investigations. Environmentalists
have cited acid rain as a major problem in today's world. It has had a
devastating effect on plant growth in many regions of our country. Your
task is to design an experiment using radish seedlings, "acid"
water and tap water to determine the effect of acid rain on radish
seedlings. You will be given supplies for growing and for measuring the growth
of your radish plants. Include in your experiment a schedule to observe and
record your data on a regular basis. Using graphs and/or statistical
measures, draw conclusions from your results.
Include any inferences that you can make regarding the effects of acid rain
on our environment. Write a formal laboratory report to detail your
procedures and present your findings.
