Honey is a thick golden sticky substance made by bees when they collect nectar from flowers. Nectar is a sugary liquid bees extract from flowers using their tube shaped tongues then stored in their extra stomach. After the bees fly with the nectar in their extra stomach, the enzymes in their stomach mix with the nectar creating honey that can be used for long term storage in their honeycomb (Palermo, By Elizabeth. "What Is Honey?" LiveScience. TechMedia Network, 20 June 2013. Web. 04 Sept. 2015.). Honey that is 100% pure, in other means mixed with no water, will be more concentrated and 85% honey will be more viscous.
In this experiment, the question “What is the effect of the viscosity of honey in a honey tube (85%-100%) on the final
If this experiment were designed to determine the amount of Fructose in a solution, describe what, if anything, would need to change in the reaction? Explain why there would or would not need to be changes. (5
The purpose of this experiment is to determine the absolute configuration of an unknown chiral secondary alcohol using the competing enantioselective conversion (CEC) method. This method uses both R- and S- enantiomers of a chiral acyl-transfer catalyst called homobenzotetramisole (HBTM), in separate parallel reactions, and thin layer chromatography to identify the stereochemistry of the secondary alcohol, whether it be an R- or S- enantiomer. Quantitative analysis was performed using a program called ImageJ after the appropriate picture was taken of the stained TLC plate. The molecular structure of the unknown alcohol was identified using 1H NMR spectroscopy by matching the hydrogens to the corresponding peak.
The mixture was poured through a weight filter paper and Sucrose washed with a 5ml of dichloromethane. The resulting solid was left in a breaker to dry for one week, to be measured. Left it in the drawer to dry out for a week and weighted it to find the sucrose amount recovered amount.

In this exercise, five reactions were performed. Of those reactions, two were negative controls and one was a positive control.
2. A test tube was then filled with 35ml of yeast and placed in the
We then took 1ml of the 1% solution from test tube 1 using the glucose pipette and added it to test tube 2, we then used the H2O pipette and added 9ml of H2O into test tube 2 creating 10ml of 0.1% solution
“We lived for honey. We swallowed a spoonful in the morning to wake us up and one at night to put us to sleep. We took it with every meal to calm the mind, give us stamina, and prevent fatal disease. We swabbed ourselves in it to disinfect cuts or heal chapped lips” (Kidd
There were five test solutions used in this experiment, water being the control, which were mixed with a yeast solution to cause fermentation. A 1ml pipetman was used to measure 1 ml of each of the test solutions and placed them in separated test tubes. The 1 ml pipetman was then used to take 1ml of the yeast solution, and placed 1ml of yeast into the five test tubes all containing 1 ml of the test solutions. A 1ml graduated pipette was placed separately in each of the test tubes and extracted 1ml of the solutions into it. Once the mixture was in the pipette, someone from the group placed a piece of parafilm securely on the open end of the pipette and upon completion removed the top part of the graduated pipette.
The 2012 documentary, More Than Honey, directed by Markus Imhoof. Bees are disappearance from the world population from disease in American. My thesis effective is the bees are dying from disease in American and all over the world.
Based on the results obtained from the lab, I can conclude that in the composition honey, there can be glucose, fructose, lactose and sucrose present in the formation of honey. Since honey passed all the tests, Benedict, Barfoed and Seliwanoff’s test, it can be safe to conclude all the solutions during the lab may be present within honey. The main components of honey would be made of glucose and fructose because those were the only two sugars that passed both Benedict and Barfoed’s test.
The general properties of fluids are density, specific weight, viscosity and relative density. The values under specific conditions (temperature, pressure, etc) can be readily found in many reference books. But in this experiment, we want to measure the fluid properties by using instruments and compare the measured values with the theoretical values. In this evaluation of fluid properties experiment, we will measure two fluid properties, which are, density and viscosity. Selected fluids were used in this experiment as samples for both experiments. Samples of fluid that we used are hydraulic oil, cooking oil, syrup and honey. All of the samples have different physical and chemical properties.
The honey bee is a very social and cooperative insect. Honey bees live in colonies with one queen running the entire operation. Honey bee hives consist of three members: the single queen, hundreds of male drones, which mate with the queen, and 20,000 to 80,000 female worker bees. Each hive also consists of developing eggs, larvae, and pupae. The number of individual bees inside the colony can depend on the location and current season. A colony can have up to 80,000 bees during the active season, which is usually during the spring with the warm weather can flowering of plants.(Orkin, 2017)
Whole Milk: We did not conduct any tests on the Whole Milk, because we had already identified the other samples. The only remaining unidentified milk sample was A and the only milk type we hadn’t named yet was whole milk. Therefore by using the process of elimination, we were able to conclude that “A” is whole milk.
Plainly, that mix of elements represents a quite difficult issue for any individual who likes to eat, since honey bees—both the trained kind and their wild honey bee cousins, both of which are in decrease—are the fundamental pollinators of numerous real foods grown from the ground crops. The issue is severe to the point that this spring President Barack Obama divulged the principal ever national procedure for enhancing the wellbeing of honey bees and other key pollinators.
There is also the potential of human error within this experiment for example finding the meniscus is important to get an accurate amount using the graduated pipettes and burettes. There is a possibility that at one point in the experiment a chemical was measured inaccurately affecting the results. To resolve this, the experiment should have been repeated three times.
