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

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

In order to find the connection between the level of education and income‚ research methods need to established. To find the relationship between the two‚ I would use the methods of survey and experiments. Survey method allows a collection of a specific population and from that populations a sample population can be extracted to represent the whole. Given a random survey preformed at a local festival would give the general population a chance to participate since all sorts of people attend community

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

The hands that I look down upon can’t be mine‚ why because they’re covered in blood. But they must be‚ I also taste the blood on my lips every time I breathe. I can’t feel my face‚ all I feel is the adrenaline rushing through me. The blood‚ the adrenaline‚ and the metallic taste‚ all mixed together is too much. I start running to my mom. I can’t yell because if I do the blood will get in and the taste will remind me of how hurt I am. How could such a childhood experience end in blood and a broken
