Designing indicators for ecological effects of bioremediation
Pentachlorophenol-contaminated soil was amended with a strain of Pseudomonas capable of biodegradation of the pollutant. After bioremediation was complete, soil was tested for indicators of ecological condition. Several direct-toxicity measures (plant seed germination and root elongation, earthworm survival) showed the bioremediated soil to be indistinguishable from clean reference soil.
Understanding the health effects of the ozone
This paper tests whether individuals engage in avoidance behavior in response to information about pollution, and whether this behavior explains the lack of epidemiological evidence of an association between ozone and health. To ascertain whether ozone affects health, I first test whether “smog alerts” lower the incidence of asthma hospitalizations in Southern California from 1989 through 1997.
What is the effect of acid rain on Lichens?
The purpose for this experiment is to investigate the effect of acidic solution on fruticose, foliose, and crustose lichens. This experiment is being done to model the effect of acid rain on lichens in the natural environment and to use this information to determine if these lichens can be used as bioindicators.
How much do students know and feel about prejudice?
We would like to do a survey research project on what students know and feel about prejudice. Our hypothesis states that the majority of the responses to the factual questions on our questionnaire about prejudice will be answered correctly.
How much does a typical student know about endangered species?
We would like to do a survey research project on student knowledge about endangered and extinct animals. Our hypothesis states that the majority of the responses to the factual questions on the questionnaire will be correct.
How does acid rain affect the growth of plants?
The purpose of this experiment was to determine to what degree acid rain affects the growth of certain plants.
What makes stars twinkle?
Have you ever wondered what makes a star twinkle? On the next clear night look at a bright star. How many blinks does it make in 10 seconds? Look at the moon, an airplane or a bright planet at night. Do these objects twinkle?
What sort of blade design works best for windmills?
The purpose of this experiment was to determine which windmill blade sizes, shapes, and angles were most efficient at producing an electrical current from a generator.
What is the most efficient angle for windmill blades?
My first hypothesis is that the closer the blade is to 45 degrees the more electricity the windmill will produce.
