Ecology Lab 2 scientific method of birds
In today’s lab we learned about the scientific method and a hypothesis. We talked about how ecologists have an issue when experimenting because they cannot control some environmental factors. Therefore the probability of repeatability in an ecological experiment in often minimal. We then went into talking about the importance of an experimenter’s hypothesis. We summed up a hypothesis as just being an assumption that could be put to the test. After we talked about some examples of a hypothesis we went into talking about the different types of research. For my two experiments in today’s lab I used natural experiments. A natural experiment is one of the most relevant types of experiments an

For my own ecological experiment and hypothesis I came up with the idea that blue birds hang around my garden because they like to eat the beetles that are around my tomato plant. There numbers would be reliant upon how high there source was, for example the more beetles there were, the more blue birds would be there. A natural experiment would be more favorable than a lab experiment because this is happening in nature. I would have to collect the size of the garden, the number of tomato plants, the number of beetles collected at a certain time, and a field camera to count the number of times a bluebird swoops in. I think stratified random sampling technique would be the best because the number of tomato plants could impact the number of birds and beetles. Season would also be an important factor for this experiment. I would expect there to be more birds, beetles, and tomato plants depending upon the size of the garden.
I think my first experiment with bees could be improved several ways. We could collect the certain type of flowers that the bees were at. Collecting the certain type of bee could also prove useful. We could go into great detail of what type of bees were attracted to what type of flower. Adding in what type of weather and what type of day got the most bees present around the flowers. I could even add in what types of bees were around what type of trees.

Over the last several years, evolution has been playing an increasingly important role in determining how various species are evolving. This is because ecology will have an impact on how quickly a particular organism is able to adapt (with: the unique challenges for a particular environment). To determine the effect that this is having requires carefully examining different species over the course of many years. This will be accomplished by comparing these changes on Darwin and Wallace Islands. Once this occurs, is when specific insights will be provided that are highlighting the underlying challenges affecting the development of organisms. This is the point that these transformations will be evident among the various life forms. (Fasolo, 2011, pp. 53 68)
Amina Hertzog Period 4 E-Glossary Semester 1 Chapter 1: Science – a way of using valid data to create knowledge and understand the nature of things such as natural life Observation – the practice of getting information and data from an experiment by looking, feeling, smelling, tasting and/or hearing Data – the information that a scientist gets from his or her experiments Inference – an idea or conclusion that was created from previous experience and information Hypothesis – a conclusion or explanation from observations made in n experiment Spontaneous Generation – the idea of living things coming from not living things Controlled Experiment – an experiment that has one variable doing the changing and the main focus of the experiment
12. Why are both natural AND controlled experiments necessary to increasing scientific understanding, and how do their roles in the scientific process differ?
Throughout the passage, John M. Barry uses a variety of methods to describe the process of scientific research. The author gives us long metaphor where a scientific investigator is like a pioneer in an unexplored region of the world. The author also gives us a little bit of background information on characterizations needed for scientific research.
1.) My hypothesis that the insects would be most repelled by the lemon plant extract was not supported. Our key findings in the experiment do not support my hypothesis because the lemon had a 60% repulsion response and was the second most repulsive behind orange with a 70% repulsion response. Although the Earthworms were repelled by the lemon plant extract, they were more so repelled by the orange plant extract. 2.)
If your loved one has recently passed away, and you've chosen to remember them with a laser-etched monument, you'll want to keep it looking beautiful. With proper care, the monument you purchase will serve as a lasting memorial to your loved one. One of the benefits of laser etching is that the work will last for years to come. However, it will require some maintenance to ensure lasting beauty. Here are four simple steps you can follow that will help you protect and preserve your loved ones monument.
Imagine if there were a significant period in American history, in which a skilled and competent writer had not taken pen in hand, to capture that period's significance or meaning. One must ask, what would be inherently lost, if all we had were self serving war stories such as, "American Sniper" or "Zero Dark Thirty," (as entertaining as they might be) to reflect upon the deeper meanings of the wars of this time. Moreover, one could only imagine the loss, if during other significant periods of American history; there were no captivity narratives such as Mary Rowlandson's. What if, "The Red Badge of Courage," or "The Things They Carried," had never graced the pages of our text books? For a decade now, students and scholars alike have waited patiently for something that is more than just
On Tuesday the 20th of September, a presentation was required of all students to show a video of individual experiments after a week was given on the day of the original assigning. Given the task of performing an experiment in order to become acquainted with the Scientific method, students of Biology 621A were required to record their experimentations in full - providing a question to be answered, constructing a hypothesis, designing an experiment that would aid in the proving (or disproving) of the hypothesis and collecting the data found from the experiment. These would go on to be graded based on their overall presentation quality, and content in regards to the mastery of the scientific method while proving its functionality and existence in scientific experiments no matter how small, while determining factors like independent or dependant variables.
A good question for this certain experiment would be: Are banana peels the best stimuli to use for the bugs due to that they are outside their natural diet of rotting
They both come from to different life styles and two different ways of living, but although they come from two different sides of this complex world somewhere Doodle and his brother and The Caged bird and the Uncaged both have something in common. While reading both novels I found out that two different things can always have something in common whether that be feelings, emotions, or even looks. It also taught me to always listen to people and their stories because two things that seem total opposite can always be alike in some way. So here is how the caged bird and uncaged bird are alike to the humans Doodle and his brother. Doodle and his brother have similarities and different things about them in The Scarlet Ibis.
The results obtained support the hypothesis at the beginning of the experiment. Apart from that, the experiment is conducted according to the instructions given. This increases the validity of the experiment.
The American Flamingo is a large species of Flamingo closely related to the greater Flamingo and Chilean Flamingo. The flamingo is apart of the bird family which mean it lays eggs to give birth to another flamingo. American Flamingos take about three years to get their pink and red feathers. In the wild Flamingos spend most of the day feeding, preening, resting, and bathing. Their young feathers are much less structed and fluffy than adult plumage.
The natural experiment is seen by some as a non-experiment. It does not test an independent variable but rather analyses the variables on offer. This has the highest level of ecological validity because there are no test conditions as such.
The purpose of including the descriptive passages of Berwick’s History of British Birds at this point in the novel was to compare Jane wishes to be free like the birds though she can relate to them at how they are excluded and left to fend for themselves. Jane want to move away from the family so she could excluded herself away from the Reed family.
Quantitative research design is an excellent way of finalizing results and proving or disproving a hypothesis. The structure has not changed for centuries, so is standard across many scientific fields and disciplines. After statistical analysis of the results, a comprehensive answer is reached, and the results can be legitimately discussed and published. Quantitative experiments
