Get on Board! The book Sugar in the Blood by Andrea Stuart, describes the genealogical research about the Ashby Family. Her research on the Ashby family begins with the journey of George Ashby, who sailed from England to Barbados. In Barbados, he would struggle to make a living. George Ashby like many other immigrants did not know how to work the land.…
The balance had an uncertainty of 0.05 grams. b. With this experiment, we had a closed environment within the vial, not allowing any particles to come in or out, further explaining why there was no change in mass. The experiment also did not cause a visible reaction. The system was the vial, cap, water, and sugar. c. 2.…
Hi Pam , how are you ? We are kind of confuse in your below comment regarding the pump ZW 8X6X10F¨, attached is the file that I received from FM back on August 19,2015 with the test points to perform and according to the Maximums Ratings attached and curves we really don´t know what is the mistake? Can you please point me out exactly what do you meant, so I can be able to revise it with the Lab Staff.…
When beginning the experiment we observed and recorded the appearance of the materials in use like instructed. We weighed our materials out on a tared scale and placed them all in their corresponding test tube. We mixed and centrifuged our solution all three times for the appropriate times and decanted them accordingly. After getting all our liquid we heated up until a white solid formed, waited for it cool…
The seconds between beginning the timer and recording data and the slight overestimation in substance amounts. This experiment could be improved by having precise measurements and using numerous catalysts during the experiment to test the speeds of the reaction.…
In the experiment 4-1 analysis of sand sample, the sand was classified in many ways. In this lab ___ had to determine the properties of five sand samples to compare them to the sand sample from the “crime scence.” The crime scene sand small little pieces of sand all the exact same size and when it was under the micropsope it was crystal and it look like the color of a rainbow but was the exact same. In sample one which was the Hawaii sand this sand was not a match to the crime scene because it had mixed sand with dark brown, light brown, a little bit of of white sand. In sample 2 which was Marco Island, Fl was not a match because even though it has white sand when it was under the polarized film half of them were crystallized and the other…
We added a piece of tape to indicate the initial water level in the cup. The cups were placed on a lab table and each week, over the course of four weeks, each student made macroscopic and microscopic observations about his/her ecosystem. At the end of the observation…
Include information that you have learned in this unit, such as what particles are, changes of state, definitions, clues that physical or chemical changes have occurred, etc. They need to have enough information that they can figure out which demonstration is a physical change, which one is a chemical change, and why. It would also be very helpful to give them a summary of clues that physical or chemical changes have occurred. Lab Report: Buddy Lab - Physical and Chemical Change Question: Sugar: Is this a physical or chemical change? What will happen if I heat up sugar and water together?…
James Beehn Feb 27/ 2017 Sugar Cube Lab The lab was to use sugar cubes and put them in a jar and shake it up and down. That was to show erosion and how erosion works. The hypotheses for this lab was for the sugar cubes to break into small pieces when you are shaking the jar up and down.…
First, we start off with the known substances given to us by the teacher. Throughout the lab, we examined the substances and took physical and chemical properties into account when trying to figure out what the unknown substances were. We observed our substances properties…
Sugar: A Bittersweet History The author's main point in this novel is to illustrate the significance of sugar in world history. Sugar has slowly made its way from the highest of society to the lower and middle classes. Sugar took over the world it went into the households of many and became apart of the diet everyone.…
Discuss the results and challenges that the students encountered. Did they prove or disprove their hypothesis (what they thought would happen)? Explain that the properties of a mixture are dependent on the amount of materials they use in their mixture. Examples can be used; e.g. I could make a very, chocolaty cake by adding more chocolate, I can dilute (weaken) the strength of cordial by adding more water.…
The setting of this story is not specified explicitly, all that is communicated is "back in the days when everyone was old and stupid or young and foolish and me and sugar were the only ones just right. . . " The setting shows that in that time there was certainly a separation of classes so to speak, and the financial differences contribute to the overall theme of the children coming to a realization that the democracy that they live in is an unequal one. That in order for it to be truly ruled fait, they would all need an equal playing field which was not the case in their society. The setting characterizes all of the characters very accurately.…
Most people blame the waistlines in America on sugar. Not to long ago people realized that eating to much sugar can give you heart disease. Every one knew that it wasn't good to eat a lot of sugary food but they didn't realize how unhealthy it is. The biggest reason that people didn't think it was that bad to eat a lot of sugar is all the misguiding research that was put out. About 610,000 people die from heart diseases from sugar.…
PURPOSE/QUESTION The question that we will answer using this laboratory report is, “How is the rate of dissolving sugar affected by changing the temperature of the water, changing the rate of stirring, and changing the size of the crystal?” The independent variable of each laboratory experiment is different, however they are all being changed to get consistent and effective results for one dependent variable. The three independent variables are the temperature of water, rate of stirring and size of the crystal and the dependent variable of the all the experiments is the rate of sugar dissolving. HYPOTHESES Below are the laboratory experiment hypotheses that we have formed as a group to figure out what will happen to the rate of dissolving under…
