c. Shower (2 points)
d. Chemical Spill Kit (2 points)
e. Biological Spill Solution (2 points)
--Answer below:
a. Eye Wash: Can be used if there is a chemical that has been splashed into the eyes. Flush for 15-20 minutes.
b. Fire Blanket: To extinguish fires. How would you use this? (-1)
c. Shower: In case of a chemical spill or fire on your body. Stay in the water for at least 15-30 minutes.
d. Chemical Spill Kit: There are different spill kits for every type of chemical spill. For instance, you would use a different kit to clean up mercury versus an acid

.:5. What is the purpose of the control group in the Scientific Method? Briefly explain and use examples. (5 points)
--Answer Below:
The purpose of the control group is the keep the experiment consistent throughout for the best results. For instance, four white carnations are placed in four vases with plain tap water. Two of them have other liquids added to them, making the plain tap water flowers the control group. They stay consistent
The group then becomes the standard of comparison.
.:6. Design a (hypothetical) experiment that adheres to the Scientific Method. Be sure to include all the necessary requirements at each step and give examples at all of the steps. Start with an observation, whether it’s real or made up, state the null hypothesis, and design an experiment (including an experimental and control group, random sampling, sample size, and reproducibility) that will allow the student to reject or fail to reject the hypothesis, and state the conclusion (20 points.)
**Note that the point value of this question is 20 points. It is imperative that one thoroughly understands and can apply the Scientific Method as it is necessary to the understanding of all science. Take the time to ensure the answer is thorough, inclusive, and complete.
--Answer Below:
There are four white carnations each in their own vases. All four have plain tap water added to them. One will also have bleach added, the

The English language is particularly complex in almost all aspects. Many of the words in the English language have different meanings for the same word. This is not unlike the definition of the different levels of usage. McCrimmon defines the three levels, formal, moderate, and colloquial, by their sentence structure, diction, and tone (McCrimmon 193). ¹ Using McCrimmon’s definitions, authors can determine what type of writing is applicable to each of the three levels. For the formal writings, an adequate example of where readers can find it is in a professional journal, and an appropriate place to find an example of the moderate level is in a weekly news magazine. Also, the best place to look for an example of the colloquial level is in certain sections of the newspaper. All of the levels of usage apply to these different types of writings and assist in defining what each level involves.
Passions drive people, and the townspeople in “The Lottery” and Paul in “The Rocking-Horse Winner” are no different. Each of the members of the unnamed town has a strong passion for tradition. The original black box used for the lottery is described as being, “lost long ago, and the black box now resting on the stool had been put into use even before Old Man Warner, the oldest man in town, was born” (Jackson 251). This sentence gives the reader an understanding that the lottery is an ancient tradition that has become an integral part of the town’s lifestyle. Such a tradition can only be carried on for this length of time if the people are passionate about preserving the tradition. Paul had a passion to be wealthy as a way to prove to his mother that he was lucky. From a young age, he saw that his family always wanted more money to support a better lifestyle, yet
The first of the two stories I chose to compare and contrast is titled “The Lottery” by Shirley Jackson and the second story is titled “The Rocking-Horse Winner” by D.H. Lawrence. I will compare each of their themes, characters, and plot developments in which they are both similar and different. One of the strongest comparison would be that both stories deal with the subject of luck in one sense or another. The Lottery being considered a game of chance in which luck plays an important factor in being the chosen winner but Luck in the Lottery has a different twist of fate because the winner of the Lottery is actually the
In our Penny Lab, we wanted to extend what we were told to do with experimental design. We’re doing this because we wanted to prove what he thought our hypothesis had been, and a hypothesis can not be true unless it can be tested. We investigated what variables made the Penny Lab easier, or harder. As a class we decided to investigate variables like, dropping the penny from the same height, and applying the same pressure to the penny for each drop. But first we had to know what variables were, and which variables we needed to use in the experiment. The variables were, the independent variable, dependent variable, the experimental group, and the control group. We investigated this to show how much water a penny could hold, but we introduced

5) This is also a quasi-experiment because they selected the variables but they can’t really control the outcome of the experiment.
Write theories for each of your experiments performed here. They may not be the same as anyone else!
Part of the scientific method is to develop laboratory procedures that test a hypothesis and answer a scientific question.
Hello this is Abrar and today we are doing a Commentary on a Poem by George Ela lyon
Learning Goal: To understand how the scientific method can be used to search for explanations of nature. The scientific method is a procedure used to search for explanations of nature. The scientific method consists of making observations, formulating hypotheses, designing and carrying out experiments, and repeating this cycle. Observations can be either quantitative or qualitative. Quantitative observations are measurements consisting of both numbers and units, such as the observation that ice melts at . In contrast, qualitative observations are observations that do not rely on numbers or units, such as the observation that water is clear. A hypothesis is a tentative explanation of the observations. The hypothesis is not necessarily
I will explain to the students that correlated groups designs are assuring group equivalence at the start of a study and can be done by using correlated-groups designs. These designs do not use free random assignment but, in other words, provide equivalent groups at the start of the study and allow other controls to be applied. An important reason for using correlated-groups designs is that they are generally more sensitive to the effects of the independent variable manipulations.
