Lab Report Density Name: Period: Problem How do you calculate Density? What units did you use for volume‚ mass‚ and density? When the cubes are placed in water which one will sink 1st? What is the ranking of the cubes lightest (1) to heaviest (10)? Is it true that the cube with the most mass will have the most density? Hypothesis I think the 1st cube was aluminum I think the 2nd cube was steel I think the 3rd cube was brass I think the 4th cube was copper I think the 5th

34-2: 1. The general trend for bone density as a person ages is a steady decline as years pass. This study shows that every decade‚ males and females bone density slowly decreases. 2. Between the ages of 20-50 females lose about 11% of their bone density and males lose about 13% of their bone density. Males do in fact lose more density then females but they lose it at a more stable and steady rate. Females lose less density at more unstable rate going from about 6% (40-50) to about 9% (60-70)

drive the sugar trade. Demand‚ slavery‚ and climate played a major role in the driving of the sugar trade. Demand was greatly increasing throughout the years. The climate of the caribbean islands where cane sugar was grown. Slavery provided “free” work to produce sugar which in turn increased profits for the farmers. In England‚ sugar was not shipped there until the year 1317. But once the sugar was becoming a popular import‚ it boomed. Sugar consumption and import grew tremendously from 1700 to

Joshua Berkebile 8-26-10 1st period Density Lab The purpose of this lab was to find the mass‚ the length‚ the width and the height of 4 different cubes so we could calculate the volume and density of them. We also had to find the density of irregular shapes by dropping them into a graduated cylinder than subtracting the starting water volume by the ending water volume. Density is how much mass is in a certain volume of matter. Volume is the amount of room that an object

Practice Density Problems Solve the following problems showing all your work including equations and units. 1. Calculate the mass of a liquid with a density of 3.2 g/mL and a volume of 25 mL. (answer = 80 g) 2. An irregular object with a mass of 18 kg displaces 2.5 L of water when placed in a large overflow container. Calculate the density of the object. (answer = 7.2 kg/L or 7.2 g/mL or 7.2 g/cm3) 3. A graduated cylinder has a mass of 80 g when empty. When 20 mL of water is

What Drove the Sugar Trade? In the late 1600s and 1700s sugar growing took firm hold in the Caribbean. France and Britain competed for domination of the Sugar Trade. By 1655‚ Britain was the biggest sugar trader. France passed Britain as the biggest Caribbean sugar trader in 1740 (oi). The Sugar Trade was driven by many factors. Some of which are capital‚ slavery and complementing industries. Money was‚ and still is‚ very important. Sugar was even called white gold by British colonists during

calculating their densities. Hypothesis If the penny was made after 1982 then its density will be higher than those made before 1982. Materials • 1 Graduated cylinder • 30 mL of water • 10 pennies minted before 1982 • 10 pennies minted after 1982 • 1 electric scale Procedure The mass of ten pennies minted before 1982 was calculated five times using the scale and then averaged. These steps were repeated with the pennies minted after 1982. 30 milliliters of water was placed into the graduated

upset with Jerry‚ Sophia always used that word “Sugar” when addressing her husband. Mustafa‚ who didn’t pay close attention to the names when people were introduced‚ thought that “Sugar” was Jerry’s real name. So‚ when Mustafa saw Jerry twirling ice cubes in his empty glass‚ he walked over to him and said‚ “Sugar‚ would you like another drink?” Mrs. Thomas wasted no time in putting Mustafa down. “Hee‚ hee‚ hee‚ hee‚” she squealed. Mu thinks ‘Sugar’ is Jerry’s real name. Hee‚ hee‚ hee. That’s the

ACTIVITY 1 MEASUREMENTS IN SCIENCE: MASS‚ VOLUME‚ AND DENSITY Purpose: The purpose of this experiment is find the density of two metals using their mass and volume. Introduction: The purpose of the experiment that was conducted was to measure and calculate the density of two different metals. Density is an important characteristic of a material. The density of an object shows how much mass is contained in the unit volume. To calculate the density of metals the experimenters had to find out the mass

Five-Layer Density Column A density column consists of layers of liquids of different densities which do not mix with each other‚ and which are clearly distinguishable from each other. The highest density material is at the bottom of the column‚ and as you proceed up the column‚ the density of each successive layer decreases‚ with the lowest density layer on top. Three methods for construction of a five-layer density column are discussed in this write-up. All methods use the same five liquids. •
