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

The Bank of the United States was a necessity that our nation could not do without because it created a national currency‚ created profits‚ and the government could control inflation. The father of this idea was Alexander Hamilton‚ who wanted a bank system similar to the Bank of England. The bank‚ that was modeled after the Bank of England‚ would be able to hold government funds‚ collect taxes‚ and make loans to the government when taxes were low. The bank would be the capstone of Hamilton’s financial

Tuskegee Syphilis experiment is the most infamous clinical study conducted in the United States between 1932 -1972. The study of natural progression of untreated syphilis in rural Africa American men‚ led to a forty year study which was controversial for reasons related to ethical standards; researchers knowingly failed to treat patients after the 1940s validation of penicillin. The patients with syphilis were never told they had it‚ were part of a case study‚ could leave the experiment at any given

If one goes out before we wake up‚ we will get two more of the same type of battery and watch it during the day. Variables Our variable is the different brand of batteries. The controlled condition is the same type of flashlights. Results Our experiment showed that Rayovac outlasted all of the other batteries we tested by at more than two hours. The Eveready battery‚ which is a regular‚ non-alkaline battery‚ lasted only 6 hours and 35 minutes. The Duracell lasted 15 hours. The Energizer lasted

Purpose This experiment shows how different concentrations of acids and bases in a solution affect its pH level. When acids and bases are combined in a solution‚ they neutralize each other. This means that depending on the concentration of both acids and bases in a solution‚ the pH will vary. A neutral pH level is 7; anything below that level is known as an acidic solution‚ while anything above is known as a basic solution. To find out the pH‚ the solutions will be diluted and tested with different
