Osmosis Experiment Subject: Professor Egg-avier Duration: 3 weeks (Oct 2nd – Oct 16th) Week 1 On October 2nd my group was giving a raw egg (weighing 58.8 grams) and placed it into a clear mason jar with 200mL of vinegar. The ph levels of our vinegar equaled a 2 which tells us that vinegar is a fairly acidic liquid. Once submerged in the vinegar‚ little bubbles began to appear around the egg’s shell. We believed this to be carbon dioxide escaping from the shell. We left our egg to sit in the

crimes occurring when there is police present. These strategies were made to reduce the crimes and make the public feel more safe in the street. The Kansas City Experiment started on October 1972 and continued to 1973 ‚ it was administered by the Kansas City Police Department and evaluated by the Police Foundation. The Kansas City Experiment tested the use of preventive patrol on crime rates and citizens fear of crime. The police foundation divided Kansas into fifteen different areas‚ and those fifteen

Observations of Chemical Changes Purpose: To observe some properties of chemical reactions and associate them with everyday household cleaning products. Procedure: In order to complete this experiment‚ I had to set up and organize my lab table. I used my 24-well plate‚ my 96-well plate‚ and the first experiment bag which included all of the necessary chemicals. I also had to gather 3 household cleaning products and a pipet in order to test them as well. The procedure involved was putting 2 drops of

Effects of Sand Mining on Palau’s Reefs Joshua Kloulubak SC-249: Environmental Concepts & Issues Instructor Sherry Ngirmeriil 21 July 2013 Abstract What are the negative effects sand mining has on Palau’s reefs? This research paper attempts to address the consequences of dredging erratically in the quest for modernization and what these threats can pose to the society should this continue in an unsustainable manner. Over the years‚ the ocean and reefs of Palau have been an important source

The effect of salt concentrations on the mass of the pear cubes ‘Pyrus’ after being soaked in water Aim: The effect of salt concentrations on the mass of the pear ‘Pyrus’ pieces shaped as cubes of 1cm. Background: Osmosis is the net movement of water molecules through a semi-permeable membrane from an area of higher water potential to an area of lower water potential. Water makes up to 70-90% of living cells and cell membranes are partially permeable membranes. Dissolved substances attract

The floating egg experiment – How much salt is needed to make an egg float? Aim: To investigate the effects of salt on the density of water (and therefore the ability to float an object in said water) and to find the amount of salt needed to float one regular egg in a glass of water. Research: Internet research shows that adding salt to water increases the density‚ and in turn makes it easier for objects to float. 4-10 teaspoons of salt in 1 glass of water is said to be enough to make one egg
