My Science Fair experiment is based on four main products: ibuprofen, acetic acid, bleach, and bread. The name of this experiment is "Bread vs. Chemicals." The goal of this experiment is to determine which chemical bread can survive in the longest. I will conduct multiple trials of each type of chemical and promptly record the results. I will use three containers, one for each chemical, and place a piece of bread in each to observe how long the bread can survive without falling apart. This experiment falls under the category of food science, which is a broad topic that applies scientific principles to better understand foods. The Maillard reaction, often referred to as the browning reaction that occurs with bread, will be considered. Additionally, I will explore the understanding of nutrients in foods and how heat, cold, and light affect them.
In addition to salad dressing, other types of vinegar are used in a wide variety of foods. Furthermore, acetic acid has several important applications in industry and commerce. However, it is important to note that this chemical should not come into contact with your eyes. One last chemical I will be using is ibuprofen, which was placed on drugstore shelves in the 1900s. Ibuprofen was developed by the Boots Company. The over-the-counter form comes in a lower dosage than the prescription form. However, the frequent consumption of ibuprofen for over two years can reduce Alzheimer's Disease by 60 percent. Ibuprofen is classified as a compound in science. It has the tendency to cause fewer stomach problems than aspirin and seems to be more effective. However, ibuprofen cannot be taken by certain people with certain conditions. Being that I am testing which chemical will make bread last the longest, I must formulate a hypothesis. The three chemicals being tested are bleach, acetic acid, and ibuprofen. My hypothesis is that if bread lasts for the shortest amount of time in acetic acid, then it will last the longest in ibuprofen. In summary, I am stating that bread will last for the least amount of time in acetic acid, it will last the longest in ibuprofen, and the time it lasts in bleach will fall somewhere in between. To achieve an answer to my question, I must record some results.
The units of measurement that I will be using are milliliters and Celsius. I will organize all of my data into a data table. Unfortunately, there are some risks associated with the chemicals that will be used to complete this experiment. These chemicals can come into contact with a person's eyes, mouth, ears, nose, and skin. In order to prevent any harm, special precautions need to be taken. The chemicals will be handled carefully, and hands will be washed thoroughly after touching any chemical before touching anything else.
Anne Zhang 3/6/14 BSGE 7-1 Lab Report Problem Paragraph 1 Question: What is the effect of temperature on the dissolving time of an Alka-Seltzer? Alka-Seltzer is made up of baking soda, aspirin, and citric acid which gives the tablet the fizz when dropped in any temperature water. “Alka-Seltzer is a medication that works as a pain reliever and an antacid.
A: The reaction with water and vinegar was the most useful in this experiment. The physical properties were very self explanatory because the texture of the powders was all different expect icing sugar and cornstarch. Also the Ph levels were very similar of six and seven for corn starch and icing sugar respectively. d) Q: How confident do you feel about your identification of the
For this experiment, you will add the measured amount of the first sample to the measured amount of the second sample into its respectively labeled test tube then observe if a reaction occurs. In your Data Table, record the samples added to each test tube, describe the reaction observed, if any, and whether or not a chemical reaction took place.
The first part of the experiment was to measure an amount of baking soda to start out with. For the first and second time we performed the experiment we used 1 g of
To continue the experiment further I can use a different source of light to test the intensity of light. For the food coloring experiment, I could use a different food color such as yellow or orange to test.
Whenever pain or a headache is felt people will immediately reach for the bottle of Aspirin they have in their medicine cabinet. For many years this has been the solution to any pain a person feels. As much as Aspirin will help to cure symptoms of pain it may also being doing the body harm. More and more studies have brought many harmful side effects to the surface. The question now comes into play of if Aspirin is actually doing more harm than good.
I blended on high to make the potatoes more liquid-like. I grabbed the cheesecloth and placed on the top of the blender. I poured the potato extract on the container and labeled it. I found out that I have to make 1% sugar solution so I grabbed the sugar and measured into 5 grams on the scale. I added 5 grams of sugar on 250 ml graduated cylinder and poured the water into the cylinder. I mixed the sugar with water and poured it into the saucepan. I refilled the water into the graduated cylinder and poured into the saucepan. I turned on the heat of the stove and saw the sugar dissolved. I poured into a container and labeled 1% sugar solution. I repeated the same thing with 1% salt solution by using 1 gram of salt and filled the water into graduated cylinder by 100 ml. I answered question three. In the first experiment, I grabbed four transfer pipets and used it to put solutions into the test tubes by 3ml. I labeled it and placed into the plastic cups so it can stand upright. I grabbed each test tube and poured 2 ml of catalase solution into it. I also tapped and swirled to measure the bubbles by using the ruler. I wrote the numbers into the lab report. In the second experiment, I labeled the room
My experiment is testing one of the five senses of my dog, Blaze. I am testing for taste. In this experiment the question I am going to answer is, Which of three flavors of treats will my dog prefer? The treats are made by the same company, Beggin’ Strips from Nestlé Purina PetCare Division, but they are different flavors. The flavors used will be Hickory Smoked Bacon, Bacon & Cheese, and Bacon & Peanut Butter. My hypothesis for this experiment is, Of the three flavors my dog will prefer the Bacon & Cheese flavor the best. I chose this topic for my experiment because I have a major interest in animals and I am hoping to get a degree in some form of veterinarian services, such as zoology.
The purpose of this lab was to show us what happens to the egg (that was in vinegar), and corn syrup when you combine it. The egg that was in the corn syrup overnight was shriveled.
n hypothesis of the experiment is that the group containing four members will perform better than the group containing two members. This is the foundation from which we have conducted our experiment.

I decided to set up a research in order to prove this hypothesis by use of my classmates. They were to help me in my research by working as samples that were on a test that will lead to valuable findings. I had to provide twenty five cups of chocolate before a lesson began to half of the samples (students) while mak...
Plan: I will first make a prediction using the knowledge I have on osmosis and I will then carry out the investigation to prove whether concentration affects osmosis in a potato. Using my results I will then try to find a pattern and prove my prediction to be correct or incorrect. After I have done that I will try and find ways in which I could improve the experiment and extend the investigation.
Nowadays, over 5 million Americans are living with Alzheimer’s disease (Alzheimer’s Association, 2013). This statistic is staggering, and unless a prevention or cure is found, it’s predicted that 16 million of Americans will have Alzheimer’s disease by 2050 (Alzheimer’s Association, 2007). Alzheimer’s disease can be either sporadic or familial. Sporadic Alzheimer’s disease can affect adults at any age, but usually after age 65. Familial Alzheimer’s disease is a rare genetic condition where one of several genes is mutated and finally lead to Alzheimer’s disease, usually in their 40’s or 50’s. (Fight Alzheimer’s Save Australia, 2010) Alzheimer’s disease is the most common form of dementia. Alzheimer’s disease is an irreversible, (Sam Fazio, 2008), degenerative brain disease that slowly destroys brain cells, resulting in impairment of cognitive function and eventually even the ability to perform the simplest tasks of daily life.( Alzheimer’s Association, 2014) Unfortunately, Alzheimer’s disease has no current cure, but treatments for symptoms are available and research continues. For instance, Rivastigmine is a parasympathomimetic or cholinergic agent for the treatment of mild to moderate dementia of Alzheimer’s disease. The drug can be administered orally or via a transdermal patch and is normally sold under the trade name Exelon. (Wikipedia, 2014) ; (AMH,2013)
