Cup B Experiment Lab Report

When the pH is not at its optimum, the differing pH's will disrupt the bonding between the R groups of the amino acid causing its structure and the shape of the activation site to change

After gently blotting, weigh all three eggs separately inside their own individual weigh boats to the nearest 0.1g and record the weights in Table 1 at time 0. Place eggs 1, 2, 3 into separate culture dishes containing solutions of distilled water (0% sucrose), 14% sucrose, and 40% sucrose respectively. The sucrose must cover the entire egg inside the culture dish before proceeding to the next step. Place a napkin down on the lab counter, at 15-minute intervals, remove the eggs from the dishes with large spoon; place on napkin and wipe off all excess water each weigh boat must be clean as well before weighing; and again, weigh each egg separately. Record the weight in Table 1: Weight of Eggs vs. Time (minutes). Replace the egg in the dish for the next interval. After the experiment is complete, return the eggs to their container and each solution to its labeled container. Clean the dishes and weigh boats and return all materials to the setup

I will have the 11 experiments set up simultaneously as the experiments will all begin and end at the same time. I will first collect 11 small beakers and two identical small measuring cylinders. I will label the beakers to identify which concentrations are in each one. The concentrations I will use are 0%, 2%, 4%, 6%, 8%, 10%, 12%, 14%, 16%, 18% and 20%, therefore I will label each beaker with one of these numbers. I will then collect the 0% concentration of sugar solution and use the pipette to transfer it into the measuring cylinder until 30ml is reached. I will put the measuring cylinder on a flat surface and read from the meniscus to ensure accuracy. This will be poured into the first beaker. I will then wash the measuring cylinder out and leave it upside down to drain whilst I use the second measuring cylinder to measure 30ml for 2% concentration. I will do this for all the concentration until all the beakers are filled. I will then collect several potatoes, a white tile, a knife, a 5mm borer and paper towels. I will cut 11 cylinders out of the potatoes. I will then measure 4cm on a ruler and cut the cylinders to size. I will try to make the cuts as straight as possible so that all the cylinders have the same surface area, and the same chance of osmosis. I will then dab-dry each cylinder, weigh them on a balance and record them in a table as the previous mass. I will dab-dry them to remove any excess water. When I start

The purpose of this lab is to test substances and to determine the physical and chemical properties of substances.

-The more dissolved oxygen in the water, the more fish is observed in that area of water.

C. An unknown, rectangular substance measures 3.6 cm high, 4.21 cm long, and 1.17 cm wide.

Two miles underground in the Vale Creighton mine lies an advance lab far from the common world. In this lab many experiments are done from sub-atomic and astro-particle physics to the reactions of fruit flies to this underground environment. But one of the experiments is how organisms react to the absence of radiation underground and how it effects life. SnoLab the company in charge of this facility calls this experiment REPAIR (Researching the Effects of the Presence and Absence of Ionizing Radiation).

2. (5 pts) List and explain the names and affiliations of the various characters/stakeholders in this story – I’m looking for us to use the story to map out the complexities that are generally associated with solving public health puzzles – the stakeholders you list and explain here should apply to many of the cases we consider going forward.

When performing the experiment, the objective was to dehydrate the Barium Chloride and to find out the mass difference from when it was hydrated. Throughout the test, it was required to check the measurements of the crucible and cover for the original mass and to be able to see the difference between a hydrated and dehydrated molecule. The Barium Chloride is then placed on top of the Bunsen burner using a ring stand and carefully placing the flames under the crucible. After waiting for about 17 minutes, which would usually allow for the substance to heat up and evaporate all of the water found within it, the crucible had to cool down for about 10 minutes. After it has cooled down, the measurement would be taken again and would be less than

First, all the materials were collected. After collecting all the materials was prepared, we started measuring the mass of the beaker and plastic

Henry Barnard Laboratory School is located on 600 Mount Pleasant Ave, Providence RI. The grades in this school range from Pre-school all the way to the fifth grade. These students are bright individuals who work hard to maintain good grades and high standards. The mission statement of this school intrigued me because it shows that the staff wants all students to excel and achieve greatness in their lives. The mission statement is “The mission of the Henry Barnard School is to provide a joyful, exceptional educational experience that empowers each child to become a confident, accomplished and innovative learner.” Another interesting aspect of the Henry Barnard School would be that this school is an active member International Association of

Beta cells are receptor subtypes of adrenergic receptor there are two known as Beta 1 and Beta 2. Beta1 receptors are located in the heart and the kidney. Activation of the beta 1 receptors in the heart have great therapeutic applications in the way when activated these receptors increase heart rate, force of contraction, and velocity of impulse conduction through the atrioventricular node. Activation of beta 1 receptors in the kidney cause release of renin into the blood which is important in the sense of since renin is able to synthesize angiotensin (powerful vasoconstrictor) which aids the increase of blood pressure. Beta 2 receptors once activated in the lungs causes bronchial dilation, activation of beta 2 receptors in the uterus leads

They all must be the same size, same type, and the same mass. Then collect 2-3 7oz cups depending on how many shells were collected. Also for this experiment vinegar is needed. Fill each 7oz cup with water and for each cup put a different concentration of acid using teaspoons and make sure to label each cup and how many teaspoons of acid is within them. For example, In cup one there is quarter teaspoon of acid. In cup number two there is half a teaspoon of acid, and in cup number three there is one full teaspoon of acid in the cup. Now before dropping the shells within the 7oz cups like most are tempted to. Go weigh the shells to see if they are or are so close to being the same exact mass. If they are not are or almost the same mass the experiment will fail. Once the weighing of the shells are done then drop one shell into each one of the cups with different concentrations of acid. Cover each cup up with saran wrap and wait at least a week. After a week or so take out the shells in the labeled cups one at a time and weigh them again so see how much the mass change from before it was dropped into the acidic

- It will act as a force that will completely neutralize F4. The force F4 and the resultant of F1, F2, F3 are exactly opposite of each other.

The overall purpose of the lab is to have the students practice designing an experiment, gathering data, and then analyzing that data to form a conclusion using the scientific method. It also served to understand key terms such as hypothesis, dependent variable, and independent variable. The specific objective of this lab is to determine whether certain human body parts experience allometric or isometric growth. Allometric growth defines when certain parts of an organism grow at unequal rates in comparison to its whole, while isometric growth is when all parts of an organism grow at the same rate in comparison to the entire organism. The specific purpose of the lab is to determine whether or not specific human body parts experience allometric or isometric growth by comparing the ratios of height to two specific body parts, in the students’ case the right hand length and head circumference, in students and newborns. The students formulated the tentative answer that if a team of four compared their height to right hand length ratio, as well as, their height to head circumference ratio, to those of a newborn’s, then the students will discover that the right hand and head experience allometric growth in humans.
