The QUESTION: Will Peeps dissolve when put into liquids? The HYPOTHESIS: Peeps are made of sugar, and sugar dissolves in water, so Peeps should dissolve in water (or other solutions) as well.

Experiment 1:
Materials – 4 Peeps, 4 600mL beakers, water, acetone, sulfuric acid, sodium hydroxide
Methods - Peeps were floated in several solutions (one in water, one in acetone, one in sulfuric acid, and one in sodium hydroxide). Peeps were observed for an hour and their reactions to the solutions examined.
Experiment 2:
Materials – 1 Peep, 1 30cc syringe, sulfuric acid
Methods – The Peep was injected with 30cc of sulfuric acid. The Peep was then observed and its reaction to the solution examined.
Experiment 3:
Materials – 1 Peep, 1 600mL beaker, Phenol
Methods – The peep was floated in a beaker containing a solution of Phenol. The Peep was observed for a little over an hour and its reactions to the solution examined.
Responding Variable: Peeps “lifespan” in terms of dissolving or not.
Controlled Variable: Solution Peep is put into.
Experiment 1 found that Peeps do not dissolve in water, acetone, sulfuric acid, or sodium hydroxide. Experiment 2 found that Peeps do not dissolve when sulfuric acid is injected directly into their bodies with a 30cc syringe, either. However, Experiment 3 proved that Peeps did dissolve almost entirely in Phenol, except for the eyes, which are apparently indestructible. Since Phenol is used in labs to dissolve proteins, this suggests that Peeps are made out of proteins/gelatin instead of directly out of sugar. Read More

...? The Scientific Method: Planter's Nuts Bag March 27, The purpose of this experiment was to determine theproportions of the nuts in a Planter's NUT.rition bag, and to determine if those proportions are regularly distributed in different bags. Study results showed that the proportions of nuts are not the same, and neither are the total numbers of the nuts between each bag. Hypothesis: There are five types of nuts in a Planter's NUT.rition bag. This experiment proposes that the proportions of the nuts in the bags will be the same in various bags. Used materials: I required three items to complete this research: 1. A notebook in which I recorded the results 2. Five 1.5 ounce Planter's NUT.rition bags 3. Five...

The Scientific Method

...found that consuming some sorts of alcohol in moderation, such as one glass of wine per day, actually had healthy benefits for the heart. Now the message changed to “drinking certain types of alcohol in moderation can actually be good for you.” The most recent studies seem to now indicate that the consumption of alcohol is irrelevant to good heart health. The grapes provide the real benefit, not the alcohol; so drinking a small amount of grape juice can render the same beneficial effects as a glass of wine. These ever-changing messages we get about the consumption of alcohol and how it relates to human health is a good example of what science can and can not do. Following the scientific method is a great...

The Scientific Method Paper

...?The Scientific Method The scientific method provides a plan for testing the validity of a ment based on the observation of natural phenomenon. A standard process of questioning and analysis is followed to obtain data to test a hypothesis or educated guess. Scientists all around the world follow this same procedure to test questions about natural phenomenon. In this way, data is normalized for results and can be compared and retested by laboratories around the world. The procedure does not have to be performed only in laboratories. The scientific method is employed by scientists at any locale, from field experiments to the most sophisticated centers for science. The following list is a summary from the plant experiment described... in the...

The Scientific Method various categories since the presented categories have fluid boundaries. For example, the item data “eating / drinking / spilling” might have entries that are redundant with entries for “preparing to eat / drink”. In this manner, Horowitz has expanded his list of top driver distractions so that the cellular phone use categories are pushed down to a much lower level. On another note, Horowitz’s classification scheme could have benefited if he chose to group together related items such as “adult distraction”, “child distraction” and “baby distraction” into one category such as “human distraction”. This would have allowed the list to be more realistic and in line with scientific principles on the presentation of data....

...The question at hand is which of the grass seeds or #2 would be best in a lawn that is 50% shaded and 50% sunny. The next necessary step in the scientific method for this experiment would be to form a hypothesis to test. In this case, I would simply state that I believed grass seed #1 would germinate at a greater rate in the sunny and shady area than would grass seed #2. I wouldn’t have any real way to research the different grass seeds so choosing one or two would be an arbitrary decision. I would then outline the procedure of my experiment. I would draw grid lines on the entire yard. Then I would sow each type of grass seed in an equal number of sunny and shady grid cells. I would ensure the...

...The Scientific Method Exercise Response to question one. The fish appear to increase when the amount of oxygen increases and theyrequire dissolved oxygen for their survival. Response to question two. In this study, we hypothesize that increasing the amount of dissolved oxygen measured in a water sample increases the number of fish seen in the body of water. Response to question three. In order to test this hypothesis, a scientific method would be used so as to establish the required answers to the specific questions. In this case, quantitative studies of dissolving oxygen in water would be used together with experimental tools. Scientific...

Applications of the Scientific Method

...Scientific Method for Business Scientific method is a process of investigation and experimentation, used to analyze, evaluate and assess a new ideaor solve a problem. It is basically formulated through a proper framework of observation, testing and reporting of results, related to an acquired hypothesis. Though the methods may vary according to the kind of subject dealt with, it primarily centers the hypothesis that is investigated and analyzed to draw a final conclusion for approving or disapproving the idea. Today, scientific methods have become one of the essential tools to be used for problem-solving and...

Application of the Scientific Method

Which is the best detergent to use when cleaning dirty clothes? Many detergents exist all for the purpose of cleaning. Some have the best advertisements and are thus popular; others have the chemicals that clean clothes without much effort, while others have negative effects on the user’s skin when frequently used. Some detergents are also used not only because of the effectiveness in cleaning but because they have fair prices and are cheaply available to many. Liquid detergent cleans clothes faster and more thorough than powder detergent. To prove this hypothesis, both types of detergents have to be used on the same type of cloth containing an equal amount of dirt or stains and under the same environmental conditions in te...
