Donesha Foster Lab Report Dr. Arrigo-Nelson Bio 120 - 1A Isopod Habitat Preference INTRODUCTION Isopods are found in different types of habitats‚ from freshwater or marine to deserts and in damp‚ cool areas. Pill bugs are slow-moving‚ crawling creatures‚ and they are cold-blooded‚ which means their body temperature is regulated by the surrounding environment (Grzimek). Like other invertebrates‚ pillbugs are ectothermic‚ meaning their body temperature varies with the environment (Pillbug Profile)

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

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

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

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 words were printed

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

However‚ the Roman society also questioned the behaviour of mankind‚ signifying their inferiority in morals and ethics‚ depicted through the forms of punishment held in the Colosseum and the removal of religious leaders such as the Druids‚ during 0-100AD.

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

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

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
