Make Your Own Ph Paper Hypothesis Text

Assignment 11: apa style hypothesis section the apa style manual is not as rigid as it was when i was a graduate student. At that time, every paper had to have sections titled literature review, hypothesis, method, results, discussion, and so on. Today, the same ground gets covered but the apa appears to be more flexible about section titles than days of old. Nevertheless, for the sake of your clarity, i'd like you to write a hypothesis section so labeled in which you state what the hypothesis is that you will be testing in your web survey. A paragraph or two stating the rationale behind the hypothesis and then the hypothesis, itself, will be sufficient. It is an educated guess because it is based on previous research, training, observation, and a review of the relevant research literature. Therefore, your hypothesis will consist of a prediction about how two variables will vary in relation to one another.

You may predict that when variable 1 is high, variable 2 will also tend to be high, and when variable 1 is low, variable 2 will also tend to be low. Or you may predict that when variable 1 is high, variable 2 will tend to be low, and vice versa. sample hypotheses here are some examples of simple hypotheses and how they might be worded in your report: it is predicted that the salary level of adults will be positively correlated with a measure of overall happiness.

It is hypothesized that a rating of how satisfied people are with their current salary will be positively correlated with a measure of their overall happiness. It is predicted scores on a scale rating the level of childhood trauma will be inversely correlated with scores on a scale of overall adult happiness. It is hypothesized that ratings on an optimism scale will be positively correlated with self ratings of job satisfaction. adding some meat the sample hypotheses above are pretty bare bones. Your hypothesis section will need a bit more meat inasmuch as we don't want it to consist of a single sentence. Therefore, you should lead into your hypothesis with a paragraph or two that provide the rationale for the hypothesis.

What is it in the literature and in your own observations that leads to this hypothesis? notice that all the examples above are based on rating scales. The reason for this is that you will be asking at least two rating scale sorts of questions in your survey which you will later test for statistical correlation.

    peel off six big cabbage leaves and put them in a blender with 12 cups of water. Liquify!
depending on how much red cabbage indicator you want to make use the optimum ratio of one cabbage leaf to two cups of water. pour the purplish cabbage liquid through a strainer to filter out all of the big chunks of cabbage. Doesn’t cabbage juice smell great? save the liquid for the experiments to follow.

Since you know that vinegar is an example of an acid, add a little vinegar to the first glass of cabbage juice. Stir with a spoon and notice the color change to red, which indicates that vinegar is classified as an acid. Try adding other test chemicals to a small amount of cabbage juice and note the color change to determine if the chemical is an acid or a base. use your cabbage juice indicator to test the acid or base properties of other common substances. Think of acids and bases as opposites acids have a low ph and bases have a high ph.

Critical Essay on Citizen Kane

Scientists can tell if a substance is an acid or a base by means of an indicator. An indicator is typically a chemical that changes color if it comes in contact with an acid or a base. As you can see, the purple cabbage juice turns red when it is mixed with something acidic and turns green when it mixes with something basic. Red cabbage juice is considered to be an indicator because it shows us something about the chemical composition of other substances. What is it about cabbage that causes this to happen? red cabbage contains a water soluble pigment called anthocyanin that changes color when it is mixed with an acid or a base. The pigment turns red in acidic environments with a ph less than 7 and the pigment turns bluish green in alkaline basic environments with a ph greater than 7. Some indicators start out colorless and turn blue or pink, for example, when they mix with a base.

If there is no color change at all, the substance that you are testing is probably neutral, just like water. Once you have tested the various chemicals and household substances listed above and have a clear understanding of acids and bases, you could make a few changes, run some new tests, and make some comparisons. Could you use the red cabbage juice and the process described above to run some tests of different brands of coffee to see if those claims are true? what happens when you put pieces of acid reducing medication in acidic liquids? choose one acidic liquid and test different brands of acid reducers to see which ones are the most effective. Just make sure you use the same dosage of acid reducer and the same form of acid reducer liquid vs tablet and the same amount and type of acidic liquid so that your tests are fair and your conditions are standardized as much as possible.

Is a liquid or a tablet acid reducer more effective? use the same brand and the same dosage of medication and put it in the same amount and type of acidic liquid. The only variable youre testing is the difference between the liquid and the tablet medication. Do they both work? does one work more quickly to reduce the acid? be sure that you only change one variable at a time, make your comparisons, and document your results.

A Narrative Essay With Dialogue

Who knew that such a simple kitchen chemistry demonstration could have such real world applications? many adults at the science fair will be glad to know the results of your research! this time, we will do some simple chemistry experiments to begin learning about acids and bases. We will see how the acidity of substances is measured we will learn about some acid base indicators we will produce ph indicating papers we will do a titration of vinegar we will search for natural indicating substances and we will determine the color scale of them. We will use also some substances and devices bought especially for our experiments.

The experiments we will describe are suited to be performed not only in schools, but also at home and for your own personal interest. Their difficulty differs from one case to another, and it is up to the teacher or parent to choose the experiment to be performed and to adapt the explanations to the level of preparation of his or her students. Do not put dangerous chemicals in containers for food use i.e: cups, glasses, bottles because they could be mistaken for beverages or foods. Never leave dangerous chemicals around the house work instead in a room like a laboratory, a cellar, or a garage. Place the containers of the remaining substances which you want to preserve in suitable places, out of reach of children. as for the safety issues and the responsibilities involved, we recommend that you read our warning page. you can buy the chemicals and the laboratory equipment for these experiments in stores which sell chemical laboratory items.
