Hypothesize Experiment

In the reading it says that a hypothesis is “a tentative explanation that can be tested and is based on observation and/or scientific

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

A1. Null hypothesis: There is no difference in the proportion of first responders reporting respiratory symptoms between groups of first responders that were exposed to the dust cloud for shorter duration of time and those that were exposed to the dust cloud for longer duration of time.

Now, you can check if your hypothesis is correct, if not it doesn’t matter because it was only a prediction. In this step your experiment should be done, now that you are complete since your question until your conclusion, you are ready to communicate your results. You could write an essay, like a final report or a poster, a display board. This method is important because you have a good order in all your project.

The introduction should include (in this order); a hypothesis, methods, and the results. The hypothesis explains why the experiment is being conducted, how it connects to previous research, and what the person conducting it expects to happen in the experiment. The methods of the lab explains how the experiment was tested and why the study was preformed in the way that it was. It is also crucial that you include a list of materials used in the section or it will prevent the reader from understanding what actually happened in the lab. The results should be both explained and shown in some sort of table/graph. The most important factor of this section should be the explanation of whether

Once that hypothesis is formed, design an experiment in which the hypothesis can be tested and go through the steps of the scientific method. At the end of the experiment, not limiting the amount of trials, it is time to write. It is important to let the potential readers know what the hypothesis was and how to go about testing it, so writing down the process of the experiment in full is a must. When the conclusion is done, and the proof reading has been completed, it is time to publish the experiment. In order to publish it, send it in to a scientific journal for peer review and criticism by those in the scientific community and

Using the scientific method helps prove previous ideas to be true by creating falsifiable hypotheses, and not being able to prove them false. Thusly, allowing scientists to accept the “Null Hypothesis”, which states that there is no correlation between your results and hypothesis. Furthermore, referring to the Null Hypothesis attempts to give experimental data meaning. If experimental results cannot prove something false, and correlates with the subject at hand, you would reject the “Null Hypothesis”.

4. How might you investigate the hypothesis using the non-experimental method? I would have to say I would have to wing how to approach my issue to solve it.

1. Experimental Design: From the work you have done this semester, choose a topic and design an experiment you would be able to perform. In your design (1) state your hypothesis, (2) identify your dependent and (3) independent variables, (4) your control conditions and (5) describe your experimental procedure.

Following that, a theory needs to be formulated. For this area, the researcher will reiterate the research question formulated into a hypothesis. This gives a structure for all other future consideration for this process, this step is identified as being critical for research. This step contains the formulation of the null hypothesis (H0) and the alternative hypothesis (H1) (Uriel, 2013).

From the Melting point experiment, it was set to classify which substance has High melting point and which has low melting point. According to the results above we identified that Compound A has a high melting point and compound B has a low melting point. According to the Pre lab, Compound B was identified as Glucose (C6H12O6) and Compound A was identified as Sodium Chloride (NaCl). With the Conductivity experiment, the first part was to find out the conductivity in Solution state, Substance A conducted electricity and also changed the color of the solution and Substance B did not have any conductivity. With the second part of Conductivity test, tried to check the conductivity in molten state. The Bunsen burner was used to melt the compounds
