Water Density Experiment: Why Does an Egg Float in Saltwater? Abstract The purpose of my experiment is to find out if an object, which would normally sink in tap water, would float when the water density is increased. The object I chose for my experiment is a raw egg. In the experiment, I changed the density of the tap water until I could make an egg float. The simplest way to change the density of water is by dissolving salt in it. I concluded that dissolving 4 teaspoons of salt in 250

1) The experiment worked because when the plant cells and the human cells were viewed in the microscope, they took on differentiating forms, enabling visual differentiation of the two forms of cells. The onion skin cell, an example of a plant cell, generally has a rigid, rectangular shape. The onion skin cells were positioned beside each other (length touching length, width touching width) and formed a checkered pattern. When observing the onion skin cell, we noticed that the cells took on a brick-like

Experiment 1 Preparation of Polymer Slime Introduction A solution of polyvinyl alcohol (PVA) can be made into a slime by adding borax solution, which create crosslinks between polymer chains. There are a number of uses of the PVA polymer: a) They may be used in sheets to make bags to act as containers for pre-measured soap you throw into a washing machine. b) Used as bags in hospitals to collect cotton cloth used in the operating rooms or to hold bed linen or clothing of infected patients

EXPERIMENT B Aim : To study level control using 1 – Element (Level) Single Loop PID. Control System : It consists of the following in feedback. LT11 - Level LIC11 - Loop 1, PID 1, of LIC/FIC11 LCY11, LCV11 - Control Valve at Inflow Pipe Special Remarks : LIC/FIC11 is in the 1 – Element position with Loop 1 in A mode. Procedures : 1. Pump P13 was switched OFF as there is no necessity to operate the product flow system. The heater was also turned OFF as there is no

Student name Professor’s name Subject title Date Impact Testing Objective The main objective of this lab is to perform tests on Charpy impacts where 1081 Steel and 6061 Aluminium are examined in order to determine the transition temperatures from ductile to brittle under various temperatures. The Charpy Impact test is used to measure notch toughness or the impact energy. The two materials underwent 8 tests at different temperatures which were obtained by mainly having the Charpy

Student’s Name Professor Course Date Investigating the Concept of Half-Life in Radioactive Decay Using Coins. Abstract The main aim of the two experiments is to verify that 50% of coins will decay (heads-up) in the first throw. In the first experiment, 100 coins (tails-up) will be placed in a box with a cover then shaken thoroughly. Coins with heads –up will be removed to represent the decayed atom. It will be realized that 52% of the coins will decay within the first throw. Similarly

Elena Milovanovic Mr. Brian Gorodetsky Science 9 November 20th 2013 LAB Density Guiding Question: How does sugar/salt affect the density of water? Hypothesis: I think that the density will increase because salt and sugar add mass to the water, therefore increasing the density. For example, ocean water, it is more dense than the regular water because it isn’t pure like regular water, it has more salinity in it making it more dense. Notes: -A sugar and salt experiment. -We
