The Domino Effect 9-26-01 Abstract: In this experiment dominos were used to investigate how distance‚ time‚ and average speed is interrelated by maximizing the speed of falling dominoes. This was done by lining up 28 dominos up against a meter stick 0.5 cm‚ 1.0 cm‚ 1.5 cm‚ 2.0 cm‚ and 2.5 cm away from each other. Before the experiment the average width of a domino was taken. At the beginning of each of these 5 trials the dominos were lined up against the meter stick. The lengths of all the dominoes

EVS LAB 1 AIM – To investigate how the greenhouse effect operates. SAFETY PRECAUTIONS- * Do not touch the light bulb as it would be hot. * Handle all equipment carefully‚ especially the thermometers and the test tubes- as these can break. VARIABLES:- INDEPENDENT VARIABLES: * Time intervals between each reading DEPENDANT VARIABLES: * Temperature readings CONTROL VARIABLES:- * Distance of one bulb to another * Height of each bulb from surface APPARATUS * 2 thermometers

The purpose of this experiment is to determine if the angle of impact affects the diameter and depth of a crater. The hypothesis was correct‚ stating that if the angle of impact changes than the depth and diameter will change due to the amount of speed and force is being put in the marble (meteor)‚ and the most effective angle for the diameter is at a 20 degree angle‚ and for depth is at a 90 degree angle. The hypothesis turned out to be true because it all depends to the angle the meteor or in this

Observations made that constituted a positive (+) for inotropic effect were signs of increased force in regards to the heart muscle contracting. Likewise‚ a negative (-) inotropic effect was noted for signs of less forceful contractions of the pig heart. A positive chronotropic effect was denoted by an increase in heart rate‚ and conversely a negative chronotropic effect was observed by a decrease in overall heart rate shortly after the drugs were administered. Discussion: The results obtained

the stroop effect. It was this type of research that inspired others and prompted them to conduct research of their own in this area of study‚ and that is exactly what was done for this laboratory experiment as well. The overall hypotheses for this experiment were‚ as expected‚ conclusive with the results‚ however‚ there was a discrepancy in the hypothesis of experiment two. The comprehensive hypotheses for this experiment were that in each experiment‚ there would be a significant effect in reaction

Piezoresistive effect is a change of electrical resistance of a conductor under axial strain. One of the main quantitative variables of piezoresistive effect is strain gauge factor (SGF). SGF is relative change of electrical resistance divided to mechanical strain (relative change of the length of the conductor). Commercial strain gauges

Introduction. The ’Stroop Effect ’ was first introduced in 1935. It originated from the theory of automatic processes. It is clear that some processing activities become automatic as a result of prolonged practice eg. Typing‚ driving‚ etc. Automatic processes therefore are fast‚ require no attention and are unavoidable. Stroop believed that there was some evidence that word identification may be a form of an automatic process. In the experiment participants had to name the colours in which the

Introduction In this experiment‚ to measure residency effect in crickets‚ the experimental organism is the house cricket‚ Acheta domesticus which is native to southwestern Asia but lives commonly in the eastern side of the United States (Ghouri 1961). I hypothesize that a residency effect will take place when a “intruder” male is placed in the container of a resident male‚ causing the cricket who owns the territory to fight more aggressively and remain dominant over that area. The independent variable

The effect is named after John Ridley Stroop‚ who published the effect in English in 1935 in an article entitled Studies of interference in serial verbal reactions that includes three different experiments.[1] However‚ the effect was first published in 1929 in German‚ and its roots can be followed back to works of James McKeen Cattell and Wilhelm Wundt in the nineteenth century.[2][3][4] In his experiments‚ J. R. Stroop administered several variations of the same test for which three different

Abstract For this lab the rate of photosynthesis was analyzed upon plant leaves. A sample of a light exposed and a not-light exposed leave were used to clearly identify the role of sunlight in the process of producing and storing energy. Aim We are trying to find proof‚ to demonstrate the necessity of light and chlorophyll in the process of photosynthesis. Background Photosynthesis occurs in organisms which contain chlorophyll. It’s a process that involves the chloroplasts to synthesize glucose
