I'd like to download the original onto Microsoft Word 6.0 or higher. No previous experience with statistical analysis is required.
Acid rain is literally acid in rain water.
The purpose of this lab is to investigate the damaging effects of acid rain on plants. Statistical methods will then be employed to determine whether any differences in germination rates is attributable to the acid rain or if it is reasonable to explain any differences as coincidences. Each group should also prepare a control Petri dish in which distilled water is used in place of the acid rain solution. After allowing the seeds time to germinate, the students should count the number of seeds that germinated in each and calculate germination percentages. The students will most likely find that fewer seeds germinate in the experimental Petri dish than in the control.
