into a petri-dish and the cylinder removed and blotted with filter paper‚ throwing the liquid away from the petri-dish after each cylinder was removed. 7) The length and texture of each potato cylinder was recorded in a table. Discussion: In the experiment‚ I believe the phenomenon to take place is osmosis. Osmosis is the movement/diffusion of water molecules through a selectively permeable membrane from an area of high concentration of water molecules (high water potential) to an area of a low concentration

English 10a 6 March 2012 Tuskegee Experiments This is possibly one of the most inhumane things to ever happen in the 20th century in the Untied States. The experiments that took place were the root of medical misconduct and blatant disregard for human rights that took place in the name of science. The ghastly medical expirements that took place between 1932 and 1972 was merely an observation of the different stages of syphilis. The men in these experiments for the most part were illiterate

“It is one thing to mortify curiosity‚ another to conquer it… (page 37)”. In Robert Louis Stevenson’s The Strange Case of Dr. Jekyll and Mr. Hyde‚ the main purpose of Jekyll’s experiments are to liberate himself‚ or in other words‚ to free himself from the evil part within him. He succeeds in many ways‚ which include the outcome of Jekyll taking the potion he created‚ and successfully releases his evil side through Mr. Hyde. He fails in many ways as well‚ including Hyde losing control and Jekyll

equation is an important second-order linear partial differential equation for the description of waves – as they occur in physics – such as sound waves‚ light waves and water waves. It arises in fields like acoustics‚ electromagnetic‚ and fluid dynamics. Historically‚ the problem of a vibrating string such as that of a musical instrument was studied by Jean le Rond d’Alembert‚ Leonhard Euler‚ Daniel Bernoulli‚ and Joseph-Louis Lagrange. Figure 1-Wave Diffusion Wave equation has many applications

Part I - Illumination Experiments (1924-27) These experiments were performed to find out the effect of different levels of illumination (lighting) on productivity of labour. The brightness of the light was increased and decreased to find out the effect on the productivity of the test group. Surprisingly‚ the productivity increased even when the level of illumination was decreased. It was concluded that factors other than light were also important. Part II - Relay Assembly Test Room Study (1927-1929)

Breaching Experiment In the eye contact experiment I decided to do this in a room with about six of my friends while watching the All Star game‚ I used my Girlfriend. I waited until everyone was focused on the game and then begin to stare at her from across the room‚ at first her reaction was to wave at me and smile then she started to look around to see if I was starring at someone else‚ then she told her best friend "I don’t know what’s his problem‚ he is being too weird." I extended my eye contact

SUMMARY The aim is to observe distillation process of ethanol-water solution and to measure the alcohol content after process in this experiment. 500 ml of solution with an alcohol content of 32% (v/v) is used for this experiment. Temperature values are recorded for every 10 ml alcohol obtained in the flask. The process is repeated in our experiment and for the first process‚ the data collection process continues until the distillate reaches to 200 ml. The concentration of alcohol is measured for

Experiment 4A – Counting Atoms in a Chemical Reaction Purpose: The purpose of this lab is to create an experiment where zinc reacts with hydrochloric acid in order to find out the number of moles and atoms of zinc reacted. This can be accomplished by weighing the sample before and after the reaction with hydrochloric acid. Data: Material Mass in grams (g) Initial mass of dry beaker 49.37 Initial mass of dry beaker + zinc 51.03 Initial mass of zinc 1.66 Final mass
