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 ’ 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 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 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

rule‚ highlighting the physical superiority held through the skill and size of their army‚ and their architectural and engineering inventions that are still in use today. 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. The Roman military depicted the superiority of the Roman Empire through their

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

Lab Report 3: Combustion of Magnesium and Specific Heat of a Metal C4C Jeffrey Silvin Fall 2017 Major Kittle Chem 100 T1 Introduction The purpose of this lab was to determine an experimental value for the heat of formation of MgO with Hess’s Law and then use the result to find percent error. To do so‚ approximately 50 mL of 1.0 M HCl was added to a calorimeter. Initial temperature was measured and then 0.25 g of Mg was added. After the reaction is completed the maximum temperature was recorded.

Aztec DBQ During the time period 600-1450 CE‚ the Aztec empire grew in size and importance. Although isolated from other areas and empires‚ they were able to sustain their empire and create a sturdy foundation. Europe‚ being the center of major trade and exchanges at the time‚ advanced as well. The Aztecs however we able to advance without the outside help Europe had. This shows the Aztecs were superior because they did not need help from outside sources to build and create ideas and cities that

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
