Eric Hou Ella Lichey, Jenna Poulton, Landen Lee Honors Biology Block 4 February 13, 2023 The Effect of Type of Oreo Cookie on the Mass of the Filling Purpose This lab aimed to determine if Double-Stuff Oreo cookies were really “double the stuff” of a regular Oreo cookie. In this lab, we compared the mass of the filling for both Oreos to determine if the mass of the Double-Stuff Oreo’s filling was twice that of the regular Oreo’s filling. The independent variable tested in the lab was the type of Oreo cookie. The dependent variable in the lab was the mass of the stuffing in grams. Two control variables are the scale we used and the same brand of cookies. My hypothesis was if I measured the mass of the filling in the Double-Stuff and regular Oreos, then it would show that Double-Stuff Oreos do not have “double the stuff” because the mass of the Double-Stuff Oreo’s filling would be less than double the mass of a regular Oreo’s filling. My group chose this hypothesis because we believed that the filling in Double-Stuff Oreos is less than twice the mass of the filling in regular Oreos.

In trial 2, the mass of the filling in the Double-Stuff Oreo was 1.9 times the mass of the filling in the regular Oreo (Lab Data Table). In trial 3, the mass of the filling in the Double-Stuff Oreo was 2.1 times the mass of the filling in the regular Oreo (Lab Data Table). The average mass of the filling in the Double-Stuff Oreo was 2.1 times that of the filling in the regular Oreo (Lab Data Table). Additionally, Anglia (2022), claims that Double-Stuff Oreos have “ just a little more than twice as much” filling compared to regular

Conclusion: Compare Trial 1 and Trial 2. The Trial 1 change in mass are 12.5g, however Trial 2 changes in mass is 1.2g. The Trial 1 change in mass is more than Trial 2. And I think the Low of Conservation of Mass violated in the Trial 1 is can be exist. Because the Trial 1 actually the soda with vinegar have Chemical reactions occur and chemical
The name of the lab is “Drops on a Penny.” I was expected to find the independant variable, dependant variable, write a hypothesis, and test the experiment. After testing the experiment multiple times, I needed to find the average amount of drops for each trial, graph them, and tell what kind of relationship it is. The last thing I needed to do was rewrite the details of the project and write a conclusion. The point of the experiment was to have the students get used to the idea of a lab, and get familiar with independent and dependent variables.
In this particular experiment the constant condition, the factor that was never changed, was the room temperature water. The independent variable, the variable the student affected, was how much water was placed into the beakers. The dependent variable, a variable that was affected by the independent variable, was the time it took for the tablet to fully dissolve. The control group, which did not receive treatment from the students, was the 50 ml of water as a result of being the medium between the three measurements of water. Finally, the experimental group, the subject that was exposed to the variable during the experiment, was the 25 ml and 75 ml of
To calculate the experimental mass the substance of each bag and the bag its self was measured using a balance. After gathering the mass subtract the mass of the empty bag to the mass of the unknown substance, in order to just have the mass of the substance. Afterward the mass of the unknown substance was divided by the number of moles recorded on the bag of the substance. The measurements are displayed on the table
Their hypothesis is that if they put salt or sugar in water it will freeze faster than the plain cup of water. They held a vote to see which one is thought of to freeze faster. 3 voted for plain water, 4 voted for salt water, and 11 voted for sugar water. Their dependent variable was the element that changed from the sugar and salt, and their independent variable was the element that was changed by the sugar and salt. The materials they used were water, food coloring, sugar, salt, clear cups, and measuring cups.
Next, I put the water to boil and started putting a magnet in each container and pot, i left one magnet in room temperature. After, I got a plastic bowl and put 50 paper clips in it. Then, after 10 minutes had past I took each magnet out from each obstacle and put each magnet in the plastic bowl(full of paper clips)for 2 seconds. Finally, I counted how many paper clips each magnet had for each trial.
The final mass could be far off due to the water and chunks of expanded gummy bears found in the beaker, leading to an inaccurate result. As well, for the sugar solution, the result could have been different if a more accurate measurement of the sugar needed was made. For the specific result, the hypothesis stated, the sugar solution needed to have an equal amount of sugar content to the gummy bear which did not occur. Ensuring that the beaker contained 10 grams of sugar was off, due to prerequisite calculations that lead to too much liquid in the beaker that needed to be removed. To be correct, the hypotheses that were wrong could
Do the same step using the second package of JELL-O. a. The second batch of JELL-O will be added to the JELL-O already in the plastic cups. However, if the second batch of JELL-O is not refrigerated before it is added, it may be too hot and may affect the first layer of JELL-O. (science buddies) In order to record my data I created a graph. I chose 5 people to complete the complete the experiment.
Group number eight’s data was different from every other group from day one to day two. While everyone else’s data showed an increase in mass, group number eight’s data showed a decrease in mass. The lowest masses were measured on either day one or day three. For those whose data was lowest on day one, it was because we
There are many gravimetric analysis methods, but the one used in this lab, measured mass via precipitation. The ion, analyte, Strontium Carbonate was precipitated in a Büchner funnel apparatus with 150 mL of deionized water and a calculated amount of Strontium Chloride
In Table 2, the initial mass of the weight buret in trial one was 15.23 grams, the final mass of the buret was 14.14 grams. The second trial’s initial buret mass was also 14.14 grams, because no solution was used in between trials; however, the final mass was 13.04 grams.
Osmolarity Lab 01 Ryanna Leslie BIO LAB 112 1.12.2023 Abstract: Six different solutions of water with different sucrose concentrations are used in the experiment measured in units of molarity. The solutions range from no solute to a high concentration of solute. They are 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, and 0.6 molar sucrose. Potato pieces are cut into similar sizes, weighed, and then placed in one of six solutions. As soon as the potato pieces are removed from the solution, they are blotted dry, and their final masses are recorded.
The purpose of conducting this experiment was to find out which brand of cake mix rises the highest, when it is fully cooked. The hypothesis was, “If cake mix can rise, then the Betty Crocker Brand will rise the highest.” The independent variable was the different brands of vanilla cake mix. The dependent variable was the rise in height of the fully cooked cake. The way that the data was measured was by taking a ruler, and the cake, and measuring the whole cake, from bottom to top.
The bulk density of a powder is the ratio of the mass of an untapped powder sample and its volume including the contribution of the interparticulate void volume. Hence, the bulk density depends on both the density of powder particles and the spatial arrangement of particles in the powder bed. The bulk density is expressed in grams per millilitre (g/ml) although the international unit is kilogram per cubic metre (1 g/ml = 1000 kg/m3 ) because the measurements are made using cylinders (Anonymous, 2012). In the experiment, the bulk density was obtained by adding 14.2565g of the ginger powder in the density.
