In the lab “All That Glitters” the objective that was focused on during the lab was calculating the density, volume and mass of various substances. The method that was used in finding the volume of the samples is called the displacement method. This is a process where the volume of the water in the graduated cylinder is calculated before and after the sample is placed. In this lab, the goal of the experiment was to identify and come to consensus about what the unknown substance might be. For this experiment, the required materials were ten pre and post pennies, unknown sample, graduated cylinder, weigh boat, water, paper towels and a weighing scale. To start off, dry the pre pennies, post pennies and the unknown substance completely with paper …show more content…

In addition, for calculating the mass of the pennies and the unknown substance, zero the balance and place it in the weigh boat to receive the data. Lastly, to calculate the density of the substances, use the formula D=MV, in which dividing the mass by the volume allows to do so. In order to be certain of the data that is collected, running multiple trials could help be accurate. A method to get an average value of the density can be expressed by the formula D1+D22. This formula basically allows one to add the data of all the trials and divide it by the number of trials that was performed. This method, not only allows to calculate the average, but also assures that the data is close to the actual value. After these sets of procedures were conducted, the unknown metal sample was identified. The unknown substance had an average density of 7.64 g/ml, which was close to the density of Tin with 7.3 g/ml as its density. The possible explanation for the differences in their values can be due to experimental errors. One of the main experimental errors that contribute to this would be, that the pennies might not be completely

Next, we determined the mass of the penny by placing it on a balance. The mass of the penny was 2.47 grams. Afterwards, we placed the penny in a beaker filled with 20 mL of 6 M HCl. In the end we put the beaker in the fume hood and allowed it to sit overnight. During day two of the penny lab, we removed the penny skin from the beaker using tweezers.

To begin with, is the experimental process used to determine the identity of the rock. In doing so one will need to discover the density of the rock. By measuring the rock sample with grams per milliliter is a way used to figure out the density. In starting one will need to measure the mass of the rock using grams. Then using a set milliliter amount of a liquid substance, such as water, one will place the rock sample inside.

The composition of the penny is a mixture of copper and zinc. The composition of a specific penny can be determined by the year of production marked on the coin. In the article “Is My Penny Solid Copper or a Copper-Plated Zinc Cent,” the writer states, “If your… penny has a date before 1982, it is made of 95% copper. If the date is 1983 or later, it is made of 97.5% zinc”(Bucki).The difference in composition has an effect on price, as copper is worth more than zinc. Since the U.S. Mint has began the production of pennies, over 1.65 trillion pennies have been made for circulation.

On our paper we predicted the amount of pennies that could fit in the boat before it sank. We tested the boat in the water and added pennies one by one. We then calculated the mass of pennies that fit in the boat and the density of it. The purpose of this Lab was to make a boat that holds as many pennies as possible and understand how to calculate

Introduction Metabolism is the sum of all anabolic and catabolic reactions within a living organism to sustain life. The energy required to perform these reactions is provided by oxygen in the form of ATP, therefore the oxygen consumption rate can be measured to determine the metabolic rate. Since oxygen is obtained through respiration, the efficiency of an organism’s respiratory system affects its metabolism. Previous studies have shown that caffeine affects the human respiratory center and occasionally dilates bronchus. It can thus stimulate human respiration and increase the metabolic rate (Haggins et al, 1915).

Volume Lab In this four parted lab the purpose is to use measurement and water displacement and calculations to find the volume of various objects. Part A questions were how much drops of water were needed to make 1mL the original hypothesis made was ten drops however this was proven wrong once the data in which twenty drops of water rose 10 mL of water to 11 mL of water, nineteen to rise from 11 mL to 12 ml, and finally eleven drops of water to rise from twelve mL to thirteen mL. Once the average was calculated which was 16.6 drops, which meant on average that's how much it needed to make one mL. By subtracting from the average with the hypothesis the hypothesis was revealed to be 6.6 drops off. Part B questions were based on water displacement. In which the question was how much was the difference between 20 mL of water and 3 marbles.

Each group was assigned a different percent of sucrose solution out of the four variables; 0% , 5%, 10%, and 15%. After we filled the beaker we then got two potato cores. Once we had the cores we cut the skin off the ends. Following this we then cut the two potato cores into four 2.00 cm potato cores. After they were cut into 2.00 cm each we found the mass.

In the experiment “Losing Your Marbles” we learned about momentum and conservation. We learned by dropping a marble down a ramp and timing how long it took it to get to a certain distance. Momentum means the mass, in grams, multiplied by the velocity, in cm/s. Or P= m x v. Conservation means something "stays the same." In this case it means that the momentum after a collision between marbles is the same as the momentum before the collision.

But we are paying a cost for the privilege of squirreling them away in drawers and on dressers. The United States government-that is, taxpayers-lost $60.2 million on the production and distribution of pennies in the 2011 fiscal year, the mint’s budget shows, and losses have been mounting: $27.4 million in 2010, and $19.8 million in 2009. In 1982, Congress authorized the Treasury to make such a change, and it did. Before then, pennies were 95 percent copper and 5 percent

Introduction The ability to taste or non-taste PTC was discovered over 80 years ago, more exactly in 1931. A chemist named Arthur Fox accidently released a cloud of a fine crystalline phenylthiocarbamide in a lab. One of his colleagues complained about the bitter taste of the dust while Fox wasn’t able to taste it. Since then it has been scientifically proven that not all human beings can taste the bitterness in Phenylthiocarbamide (PTC) (Macbeth 1997).

The purpose of this lab was to change pennies from copper to silver to gold, like alchemists have attempted to do in history. Through the data and observations gathered throughout this experiment, it can be concluded that the pennies were not changed into a different element. For example, the density of the penny from 2005; which was the penny that was experimented on to see whether or not it could turn into silver; was 4.62 g/cm3 before the experiment and 4.89 g/cm3 by the end of the experiment. If this copper penny really would have turned into silver, then the density of the penny would be 10.49 g/cm3; which is the density of silver; by the end of the experiment. The penny may have turned silver in color, but this was only because it was plated in the zinc that was added to the beaker of water in the experiment.

The materials I used for this experiment were foam, duct tape, tin foil, yarn, cardboard, and a tin can. My idea came from the idea of a cooler because of the inside foam insulation. I got the idea of the duct tape when I thought about air ducts and how they wrap them in duct tape to repair them, and how you can't feel the heat from the ducts. I got the Idea for the tin foil, because tin foil is used for baking. I got the idea for the yarn because I thought it would be good insulation for a top because cotton is a good insulator and cotton is like yarn.
