EGG – ITS COMPOSITION AND FUNCTIONS Eggs are laid by females of many different species‚ including birds‚ reptiles‚ amphibians‚ and fish‚ and have probably been eaten by mankind for millennia. Bird and reptile eggs consist of a protective eggshell‚ albumen (egg white)‚ and vittles (egg yolk)‚ contained within various thin membranes. Popular choices for egg consumption are chicken‚ duck‚ quail‚ roe‚ and caviar‚ but the egg most often consumed by humans is the chicken egg‚ by a wide

The Floating Egg Problem Introduction: This experiment was constructed to aid in the practice of using the volumetric system and the glassware that determines volume. Volumetric glassware contains an accurate amount of liquid and also measures the volume accurately. Density is a measure of how much matter takes up a certain amount of space or volume. The more matter you can pack into a certain space‚ the denser it is. Although we often confused the two‚ density and weight are actually two

Daniel H. Perry Procedures of Measurement and Density of Sugar in Soda Introduction The main focus of this lab was to acquire a basic understanding of how to properly use measuring devices in order to determine properties of a liquid. These properties are volume‚ mass‚ and density. The following measurements were obtained in the lab: density of water‚ both density and concentration of aqueous sugar solutions‚ and density of various soft drinks with respect to sugar. Additional experience was

Problem: How much does an object accelerate when the height of the drop is increased or decreased? Preliminary Research: When going into this experiment I already knew that air resistance is the force of the air repelling against the object and slowing it down slightly. Gravity is the force that holds something down to the ground. I know without gravity everything and everyone would be floating around everywhere‚ like astronauts on the moon. Air resistance and gravity work together in a lot of
