Scientific Investigation Module #1
Feet Size vs. Height of Individual pg.1
Module 1 6/2/2011
Type of data: Correlative
Hypothesis: Not supported.
Relevance: This is relevant because we cannot assume that just becuase people are tall, they have large feet. Taller people may have the same feet size as a short person, but the taller person just has greater height. Feet size may have alot to do with bodybuild and stature, not just height. A person's skeletal structure may need larger feet to support it. In this case, bone structure and density have a lot to do with feet size.
Chocolate Milk Good for Atheletes? pg. 2
Module 1 6/2/2011
Type of Data: Anecdotal
Hypothesis: Supported
Relevance: Athletes who drank chocolate milk exercised longer than athletes who consumed the carbohydrate drink. Yet, there were no other significant findings or between chocolate milk drinkers and other fluid drinkers.
Testing Food Samples pg. 3
Module 1 6/3/2011
Type of Data: Direct Evidence
Hypothesis: Not Supported
Relevance: The results were identical to the nutritional labels partially, but not completely. I was surprised to discover that all of the food samples were not as nutritious as the nutritional labels on the food packaging claimed them to be.
Environmental Utilization for Terrestrial Isopods pg. 4-5
Module 1 6/3/2011
Type of Data: Direct Evidence
Hypothesis: Not supported
Relevance: Natural factors, such as plants and other organisms may have affected the presence or absence of the isopods in the soil. For example, larger organisms may have been predators to the isopods and certain plants may have been threatening to the isopod or negatively impacted the isopods environment.
Ecology Module #2
Glen Ecosystem Evaluation pg. 25-28
Module 2 6/23/2011
Type of Data: Correlative
Hypothesis: Supported
Relevance: The Glen does have low biodiversity and that is not a sign of a vibrant ecosystem. However, there is very little pollution in the Glen, which is good for the survival of animal and plant life. As a result, the few species that do live in the Glen have a viable environment to thrive in. There are several varieties of autotrophs in the Glen area, meaning that the level of producers in this ecosystem is high. Yet, there are not many consumers in the Glen, either primary or secondary. The lack of consumers in the Glen is a factor that contributes to its low biodiversity.
Acid Rain Effects on seed germination pg 29
Module 2 6/24/2011
Type of Data: Direct Evidence
Hypothesis: Supported
Relevance: The acid rain prevents germination. Not only are the seeds affected by the acid rain, but the soils basic nutrient system is also affected. Since acid rain destroys the soils nutrients, the seeds are unable to grow. The tomato seeds in the petri dishes with pH 2 and pH 4 did not germinate. We believe this is due to the acidity of the water in these petri dishes. Yet, the final petri dish did show signs of germination.
Environmental factors: Human overpopulation pg. 30
Module 2
Type of Data: Correlative
Hypothesis: Supported
Relevance: It is obvious that the earth may become overpopulated with humans sometime in the near future. Overpopulation is an issue where the numbers of an organism exceed the carrying capacity of its natural habitat. The affects of overpopulation on human society are many. The demands of increasing population magnify demands for natural resources, clean air and water. Human survival depends on population control as well as a better management of natural resources. Being limited in quantity, natural resources need to be managed accordingly.
Genetic Module #3
What is a cell?
Module 3 6/4/2011
Type of Data: Direct Evidence
Hypothesis: Supported
Relevance: Key difference are listed between each type of prokaryotic and eukaryotic cell. Several examples of where each prokaryotic and eukaryotic cell might be found are given as well as other information about the cell types.
Cheek Cell DNA Extraction and Forensic Criminal Scene Investigation pg.7
Module 3 6/8/2011
Type of Data: Direct Evidence
Hypothesis: Supported
Relevance: Extracting DNA is useful because it allows scientists to study an individual's genome and observe the structure of a specific human's DNA. The genetic makeup of human DNA is also helpful in assisting researchers in creating better and more effective treatments for diseases.
Human Inheritance pg. 8-9
Module 3 6/9/2011
Type of Data: Direct Evidence
Hypothesis: Supported
Relevance: This lab experiment shows direct evidence that unique traits are passed down from generation to generation. This lab also identifies two types of traits, which are dominant traits and recessive traits. This lab discovered that having a dominant trait does not necessarily mean that it is the stronger trait or the better trait. That all depends on several factors. Soemtimes, it may be better to have the recessive trait shown physically in an individual, then having the dominant trait. This is obvious often times in illnesses like Huntington's disease, where the dominant trait triggers the genetic disease.
Crime Scene Analysis pg. 10
Module 3 6/10/2011
Type of Data: Direct Evidence
Hypothesis: Supported
Relevance: DNA fingerprinting is very helpful in pinpointing suspects in criminal and legal cases. Furthermore, DNA fingerprinting is very often the most accurate type of physical evidence in criminal cases.
Solving Genetics Problems pg. 11-14
Module 3 6/9/2011
Type of Data: Direct Evidence
Hypothesis:
Relevance:
Evolution Module #4
Evolution: Lab Module 1 pg. 15
Module 4# 6/20/2011
Type of Data: Direct Evidence
Hypothesis: Supported
Relevance: The lab report showed that all species on earth have strong potential fertility and population size would continuously grow if all members of a specific species were born and would reproduce again.
Evolution: Week 1: Module 1 and 2
Module 4 6/20/2011
Type of Data: Direct Evidence
Hypothesis: Supported
Relevance: The dichotomous key is very useful in classifying different organisms. Not only is it helpful in classification, but it is also helpful in organization. The key is helpful in organizing various animals or objects into a proper sequential order. Without the use of the dichotomous key, the process of classifying different objects and organisms would be very difficult and time-consuming. The cladogram is also useful in identifying different species and tracking the history of similar animals.
Microevolution and Natural Selection pg. 19-23
Module 4 6/21/2011
Type of Data: Direct Evidence
Hypothesis: Supported
Relevance: The Hardy-Weinberg equilbrium was correct in predicting that populations would evolve as a result of radnom mating. In random mating, multiple alleles that each have their own differences interact with each other allowing for variations to occur in successive generations. Consequently, evolutionary change occurs over time.
Journey of Man Summary Question pg. 24
Module 4 6/22/2011
Type of Data: Correlative
Hypothesis: Supported
Relevance: This lab discussed what might be the most important factor that influenced the way modern humans appear today. One of the things that might have influenced the way human beings appear today is the type of environment they were living in. This lab also discussed whether humans were still evolving. Humans probably still are evolving today, but not at the pace they were thousands of years ago because of advances in modern technology.
