| Analysis: The number of heart beats increase‚ as the caffeine concentration increases‚ as shown in the results. Conclusion: The hypothesis was correct as the heart beat did increase as the caffeine concentration increased. However‚ this experiment could have been more fair due to the following: * All the daphnia used

Experiment 1: TLC Analysis of Analgesic Drugs 1/23/2011 Purpose: The goal of this experiment is to test our knowledge and understanding of TLC analysis by having us do a TLC analysis of analgesics to figure out their main chemical components. Calculations: 1.) Rf = Distance spot traveled/ distance solvent traveled Results: Table 1: TLC Analysis Analgesic Drugs | Rf Value | Acetaminophen | 0.323 | Aspirin | 0.597 | Caffeine | 0.081 | Unknown 154 (Plate 1) | 0.081‚ 0.306‚ 0.597

As stated above‚ humans have a need to be accepted by others and for this to happen‚ each individual within the group must share the same belief as the group.An experiment by Donna Webster and Arie Kruglanski showed that dissenters who voiced their opinion were rejected by the entire group and this explains that we tend to conform to behaviors around us for the sake of not being rejected(Kruglanski & Webster‚ 1991)

Liza Handler Experiment Background: Squid is a keystone species‚ negative effects on them can have major consequences down the line. Nearly all of the animals in the oceans ecosystems either eat squid‚ or are eaten by squid. Squids not only have a vital role in our Oceans ecological community‚ but they also are important economically. Squid is a main source of food for the tuna and hake‚ two major commercially important fish. In 2011‚ fisherman harvested a total of $100 million worth of squid

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

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
