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

“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

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

Abstract The purpose of this paper was to critique a research paper that explored the experiences and attitudes of mental health nursing students towards using cigarettes as a means of controlling client behavior. A survey was used with the information broken down into graphs. Overall‚ the data showed that the respondents generally did not like this practice. There were both ethical and moral dilemmas involved using lifestyle risk factors as rewards or a patient’s addiction as a way of modifying

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

they would like more. After the observation stage‚ I wanted to make sure that the play activity I had in mind‚ suited their age and stage of development. I also made sure that the activity is safe and that it included the PILES development and that it s based on future learning. I made a sketch plan for myself without telling the children about it and I see what I need for all that. I consulted with the manager to see if the materials I needed could be provided by her.

Is it normally acceptable to experiment on non-human animals to develop products and medicines that benefit human beings? New scientific research has cast grave doubt on the safety testing of hundreds of thousands of consumer products. Everyday products‚ from soft drinks to paints‚ contain numerous synthetic chemicals. Official assurances of the safety of these chemicals are based largely on animal experiments. But recent results from a consortium in America suggested such assurances may be worthless
