For this experiment‚ there were four onion bulbs labeled A‚ B‚ C‚ and D. Bulbs B‚ C‚ and D were each immersed in a different concentration of coffee. Bulb A acted as the control because it was not immersed in any concentration of coffee; instead‚ the onion roots grew in water. The following is a list‚ in order‚ of the concentration of caffeine bulbs B‚ C‚ and D were in: 0.1%‚ 0.3%‚ and 0.5%. Four test tubes were gathered to set up the experiment‚ each holding an onion bulb. After each day‚ every

For this experiment you will need green and white seedling The purpose of this experiment was to test two different hypotheses about the credibility of Mendel’s law of independent assortment and law of segregation. First is that the first plant is the product of a monohybrid cross. A monohybrid cross is “a cross between two organisms that are heterozygous for the character being followed” (Urry‚ G-21). The monohybrid is represented through a phenotypic ratio of 3:1 and a dihybrid cross is represented

1. Dancing Raisins Here’s another quick and easy science experiment. All you need is a glass of clear soda‚ such as ginger ale or club soda‚ and several small raisins. Fill a glass with soda. Leave about ½ inch (12.5 mm) of space at the top. Drop the raisins in. Those tiny bubbles attaching themselves to the raisins are carbon dioxide (CO2) bubbles. The irregular surface of the raisins enables a lot of CO2 to accumulate. When enough gas bubbles attach to the raisins‚ they act like tiny balloons

antisocial behavior. The experiment was undertaken with pastoralists from southern Namibia and the study area is divided into two parts according to the exogenous differences in biomass production (a high yield and a low yield area). In this paper‚ biomass production is taken as a proxy of resource scarcity and moved the lab to the field to observe fundamental human behaviors‚ such as risk aversion‚ time preference‚ trust‚ spite‚ and cooperation. There were two experiments‚ such as‚ a one-shot public

Spirit Burner Experiment Aim: To perform an experiment in the labs to determine the heats of combustion of selected alcohols and then to use this information and the gathered data from chemical data sources to determine trends in the longer chain alcohols. The Variables that MUST be controlled throughout the experiment are: • The height from spirit burner nozzle to the base of the water filled beaker • Air drafts around the room must be kept to minimum so as to keep the heat on the base of the

Introduction Milgram Experiment Method 40 men were recruited for a lab experiment investigating “learning”. In exchange for their participation‚ each person was paid $4.50. After the WWII‚ Stanley Milgram a psychologist of Yale University posed a question‚ “Could it be that Eichmann and his million accomplices in the Holocaust were just following orders? Could we call them all accomplices? These men were introduced to another participant who were actually actors. These men were given role

Report of Experiment 28 - Digital Electronics with Altera Quartus Student ID 200907437 (group 41) ELEC 211 30 Nov 2012 and 7 Dec 2012 Abstract The experiment mainly introduced the fundamental function and application of the software Altera Quartus II with the DE1 development board and a host personal computer. The whole experiment contains five sections (or targets). The experimenters followed the guidance from the lab handout and accomplished the targets designed in the five sections. After

involved when two incompressible substances are mixed together. 12 experiments were performed‚ 10 involving the combination of a measured amount of hot and cold water and 2 involving the combination of ice and liquid water‚ the majority of these experiments were performed three times. The average variance in final temperature for each experiment was less than 10 percent providing proof of repeatability. Equipment used during the experiment included a gram scale‚ thermocouple‚ Styrofoam cup‚ glass beakers

HOOKE’S LAW EXPERIMENT Aim: The aim of this experiment is to determine the force constant (k) of the particular spring used. Introduction Hooke’s Law: Hooke’s Law is a law that shows the relationship between the forces applied to a spring and change in its length (extension). The relation is best explained by the equation: F= -k Δx F: Is force applied to the spring this can be either the strain or stress that acts upon the spring. k: Is the spring constant and details how hard
