Chocolate Chip Cookies Lab Report

In class there was an experiment done to help learn the scientific method and how it is done. The experiment conducted was on chocolate chip cookies and how they changed when only one variable was changed in the recipe. After watching the video “The chemistry of cookies” we learned what was happening from the beginning to the end process of making a batch of cookies. The process that will have the greatest effect on the cookies we made is caramelization. Caramelization occurs at temperatures between 356 degrees Fahrenheit and 390 degrees. Caramelization is what happens to sugar molecules break down on high heat which forms the sweet and nutty flavors (the chemistry of cookies). This is important because the original recipe called for a temperature of 375 degrees and the experimental …show more content…

The cookies were said to have baked between 9 and 11 minutes so for both the control and experimental batch they were cooked for 10. Also, with both control and experimental batches no nuts were added. The only thing that changed between the recipes is the cookies temperature which changed from 375 degrees to 325 degrees. In the graph about appearance there will be a distinct difference between the two cookies. One cookie is light in color, while the other cookie is more carmelized in color and a darker brown. In the graph about texture we can see that the experimental cookie is much softer. The first cookie had more of a crunch to it,it was not hard but it had a crunch. While the second cookie had no crunch at all, it was just soft and broke apart without a snap. In the graph about smell and taste it is seen that the control group was not that much off from the experimental group. The control cookie was definitely completely cooked and had a caramelized smell and taste about it. The experimental cookie tasted a little raw and even had that raw cookie dough kind of smell to

More water would make the solution less concentrated, causing the water move from the less concentrated solution to the higher concentrated gummy bear (expanding cell) and vice versa. Consequently, we must use the same amount of amount in every solution to ensure a fair test. Color: Each color of gummy bears represents a different flavor. To achieve this, different levels of glucose are contained in the gummy bears and, therefore, to keep the test fair, we will be using the same color of gummy bears throughout the experiment.

The powder makes bubbles that occurs immediately after adding liquid-based ingredients. While in the oven, it produces a chemical reaction that also creates bubbles to make the mixture rise. It changes the cupcakes identity and the form because the baking powder produces a carbon dioxide gas. The powder is broken

The data obtained (energy content) in the experiment was significantly inaccurate compared to the actual energy content of the marshmallows. Even though the result was inaccurate it still agreed with the hypothesis, the white/original marshmallows have slightly lower calories (energy content) compare to the coloured marshmallows. In my opinion, this slight change in calories occurred because one of ingredient, food colouring. Though food colouring doesn’t have much effect on the calories yet, it still affects the overall calories to a certain extent. Therefore the investigation agreed to the hypothesis to a certain extent.

When amylase and starch were mixed together with three drops of Lugol’s, the testing for starch tested negative and there was a color change to yellow. This happened because, after starch and amylase were mixed along with ten drops of Benedict’s, the testing for sugar tested positive with a color change to

In a quaint Massachusetts town located 21 miles south of Boston, Ruth Wakefield, a baker who ran the esteemed Toll House restaurant, created the infamous chocolate chip cookie that people enjoy all around the world. In her 1938 cookbook titled “Tried and True,” Wakefield first displayed the crispy and chocolate chunk filled cookie as an accompaniment to ice cream. Due to the cookie’s sheer popularity, the recipe made an appearance the following year on Betty Crocker’s radio program, further cementing the cookie's reputation in American pop culture as the go-to cookie. Although chocolate chip cookies still almost unanimously reign supreme as America’s favorite cookie, there are still countless different ways to prepare them. An example of a dissimilarity can be found in the type

For example, in the response experiment, a yeast solution was prepared without sugar mistakenly and thus had to be prepared again. This suggests that other errors in preparation and measurement could have been encountered. For the future, careful measurements using clean uncontaminated flasks would eliminate possibilities of such error. A source of error for the metabolism experiment involves the yeast’s yellow hue. It is possible that the color of the yeast caused the solution to look more

1% glucose, 1% maltose and 1% lactose all progressively get positive results by changing colours to reddish brown at the end of this experiment. In this case the aldehyde functional group that is present in the products (monosaccharides and some disaccharides) in this reaction is able to reduce copper in the presence of alkali and this produces colour changes while converting to an aldose sugar. Honey is made of fructose and glucose which instantly turned brown after the test-tube was placed in the boiling water because of its active aldehyde and carbonyl group. The copper (II) sulphate present in the Benedict’s solution reacts with electrons from the aldehyde group which results in a redox reaction to from cuprous oxide, a red brown precipitate that seen in all of the above mentioned solutions (Hill, 1982). Beer also gave positive results because it contains aldehydes and ketones (i.e. acetone, trans-2-butenal, furfual) during its beer production process where the sugars are converted through fermentation (Hill, 1982).

In 1492 Christopher Columbus an explorer, navigator and colonizer from Italy sailed West on the Atlantic Ocean to declare that the earth was round when everybody else said the earth was flat! Although Columbus’ speculative proposal was to reach the East Indies by sailing westward; yet his daring and bold audacity of hope of exploration led to the discovery of the New World! In 1904 Mary Bethune wanted to start a college for African American girls but she only had $1.50.

I was unhappy to find that the dry, crumbly texture of the cookie left my mouth covered in a flour-like-powder after thanking my first bite. There was crystals of sugar covering the lower surface of the cookie, which also caused an distasteful crunch. When my dad bit into the cookie, it fell apart into crumbs which landed all over is lap as he furiously exclaimed, “What a mess!” The cookie had huge chunks of chocolate throughout, which made the overwhelming majority of every bite chocolate. Perhaps that the lack of cookie dough in the cookie caused both of these issues(the unpleasant texture and the unbalanced ratio of cookie to chocolate).
