Density: Using Experimental Techniques to Solve an Inquiry based problem ABSTRACT The topic of this experiment is Density. The objective is to find two ways in which the density of a given object can be determined‚ and to find out which of the two ways is more accurate and hence better to use in such a case. The two methods used in this experiment are finding the dimensions of the object and water displacement. These are two ways of finding the volume of an object‚ and they were chosen since

Experiment #2 “Density Determinations” Report The objective for experiment #2 was “to determine densities of objects/salt solutions with different concentrations of salt‚ to see how density changes as a function of concentration.” In experiment #2‚ part II‚ calculations of Density of NaCL solutions were made from 0%-25% NaCL concentration. My hypothesis was that as the % increased‚ so would the density‚ because adding weight would increase the density of each solution. The density calculations in

What Happened in Chicago “I can’t believe he would turn me in like that!” I ranted. “After more than 30 years of friendship. How could he?” “Well‚ you did rob a bank‚ and were the most wanted man in Chicago.” nagged my cell mate‚ Ben. Ben was a very buff 45 year old that has been here in and out. Each time he’s here‚ he claims it to be a different fist fight. Although‚ he’s here almost every month‚ so who knows the truth? “Let’s go people!” barked the police officer. It was time for dinner. It

The story of what had happened to the Alexandrian’s was the first thing that pierced your ears after entering the common area - which was nothing more than the cafeteria. The second thing that you noticed was the strong smell of alcohol and tobacco filling the room‚ making

Upon completing What Happened to Johnnie Jordan?: the Story of a Child Turning Violent‚ I was struck with a feeling of frustration and agitation toward our current juvenile system. Johnnie was continually let down by his family‚ Children Services‚ foster care‚ and the juvenile justice system. He repeatedly displayed behaviors of a child in desperate need of help and he did not receive it. Although I believe that Johnnie should have been punished for his actions‚ I think that the system that he

What Happened to the Lost Colony? There are many theories on what happened to Roanoke the Lost Colony. That they went underground‚ settled at a different place‚ tried to go back home but there’s only one that could’ve happened to them. When John Smith left to go back to England and returned three years later with no people to come back to except for “CROATOAN” carved into a tree. I believe that the English used the buildings to make boats‚ that there was no war with the Native Americans‚ and that

Hamza Aziz General Chemistry I Lab 09/12/2007 Lab 7 Density of Sprite and Diet Sprite Abstract: The density of regular Sprite was found to be 1.037 +/- g/mL. compared to Diet Sprite which was 0.9965 +/- g/mL. Among the three volumetric glassware Pipette was most precise (ó=0.0016 g/mL). Burette was the second best (ó=0.0023 g/mL) and graduated cylinder was the least precise (ó= 0.007 g/mL). Density was found to be intensive property. The slope of the graph of mass against volume was 1.05
