| 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

In this experiment‚ we planted bean plants and put stress on them by rubbing them a certain amount of times a day. This was to see how they might survive in a windy area or in an environment where they might constantly be touched or moved around. The bean plants were

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)

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

The purpose of this lab was to determine if a there is a change in mass when a gas is produced and determine if gas has mass. To conduct this experiment‚ the group must be careful not to let the Alka-Seltzer tablet get wet before the bottle is closed by wiping the lip of the bottle and the cap so it remains dry‚ or risk gas escaping into the air and not being captured by the bottle. Also‚ the group must be sure to close the bottle tightly with the cap‚ because gas may escape this way as well. During

PE/DB/0313 FLUID MECHANICS Page 2 of 2 H7 Friction Loss in a Pipe Description Experiments The Friction Loss in a Pipe apparatus allows students to study the change in the laws of resistance for laminar to turbulent flow and find the critical Reynolds number. The apparatus shows the flow transition point from laminar to turbulent‚ and is ideal for demonstrations as well as student experiments. Study of friction loss in a pipe‚ including: The equipment is a small-bore‚ straight

“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

Title: An investigation into the impact of group pressure on an individual’s estimate of the amount of beads in a pot (ginger granules in a jar). IV = Group/Individual DV = Individual beads estimate Abstract This experiment investigated the impact of group pressure on the individual. The hypothesis is that group pressure does indeed impact on the individual and in this case the individual’s estimate of the number of ginger granules in a jar. Participants were asked to make a judgement of
