submarine Adventure: Density Saves The Day‚; I had made many of the calculation for the best result of the lab. My calculations section contains: the volume of the unknown metals‚ where I figure out the volume of each metal so that I will be able to determine its density in order to find its identity; the density of unknown metals‚ where I figure out the density of each metal so that I will be able to determine its identity; percent error between known and unknown metal densities‚ where I figure out

Ashley Robins 9/13/11 Honors Chemistry Period 4 Density Lab Purpose: 1. To determine the density of a solid using different laboratory techniques for measuring volume. 2. To use the intensive property of density to identify an unknown substance. Procedure: 1. Obtain a bag marked with a number containing a cube and a cylinder from the teacher. Record the number on the bag in the data table. Density of a cube: Using a balance‚ record the mass of the cube to the nearest tenth of a gram

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

An Iranian General believes they are being set up‚ maybe by Israel. They struggle with deciding to attack first or not. CNN covers the attacks‚ but makes a decision to report only cleared information. The US finds evidence of a chemical lab in Iran. Sarah fears that Muller will take the world down with the “Samson Option‚” a last resort‚ nuclear attack. Sarah contacts KING HASSAN of Jordan for information and evidence

Nutrition Density Essay After having calculated the nutrient density of seven food groups in a spreadsheet‚ the food group that came to have the highest Nutrient Density was the vegetable group obtaining an average of 7.76712 Nutrient Density. The food group that came to have the lowest Nutrient Density was the “junk food” group‚ having an average of 0.24845 Nutrient Density. One of the factors that contribute to foods having a high or low Nutrient Density is the amount of calories. I noticed that

Density (Linearized plot) TA: Blue Rex rex Group Members: Billy and Mandy Tuesday; 1200-1350 Abstract: In this lab the density of hand-made clay balls were calculated to understand how scientists model physical effects and to understand logarithmic plots. The hand-made balls ranged from diameters of 2cm to 6cm and were measured with vernier calipers by each member of the group. A total of 6 independent measures of each diameter were taken to establish uncertainty. The clay balls were then

Density Lab Partners: Betty Alcaraz Date: 9/10/13 Teacher: Wright Class: 7th period Introduction/Purpose: To determine the densities of unknown substances. Pre-Lab: 1. Which is heavier‚ a pound of feathers or a pound of lead? a. A pound of lead. 2. What is the density of a mineral if 427 g of the mineral occupy a volume of 35.0cm3? b. 12.2g/cm3 3. The water level in a graduated cylinder stands at 20.0 mL before and at 26.2 mL after a 16.74 g metal sample

For this lab‚ I decided to focus on relative dating in studying things of the past. I found this the most interesting form to examine. Relative dating doesn’t give one an exact date but can give a good time frame of an artifact. It is used by looking at sequences and layers with regards to the soil for excavating. This is known as stratigraphy (Bahn‚122). It was inspired by geology in looking at layers of soil (Dating Archeology‚ 2016). As an archeologist using this method‚ one would say‚ “the underlying

Relative Velocity and Riverboat Problems On occasion objects move within a medium that is moving with respect to an observer. For example‚ an airplane usually encounters a wind - air that is moving with respect to an observer on the ground below. As another example‚ a motorboat in a river is moving amidst a river current - water that is moving with respect to an observer on dry land. In such instances as this‚ the magnitude of the velocity of the moving object (whether it be a plane or a motorboat)
