Experiment: The purpose of this experiment was to test which variables affected the horses sympathetic nervous system leading the horse to stress and drooling. There were multiple variables tested such as the dilation of the horses eyes‚ if the horses ears were up and lastly if the horse drooled. In order to conduct this experiment‚ we had one horse getting honked at by a car and then testing those variables to

This experiment tested the growth of E.coli with inserted plasmid on an agar plate with Ampicillin. One colony of E.coli resistant to Ampicillin was grown during this experiment. The overall goal of the experiment was to successfully grow E.coli on the agar plate‚ which would show that the plasmid had been effectively inserted into the bacteria’s genes. This experiment helped students understand how plasmids were inserted into bacteria and used in real life situations. It also showed how the bacteria’s

compensation for participating in this experiment. These participants were divided into six groups based on where they were sitting. Design The Stroop Test was used in order to test the effect of interference on reaction time. This was done by using three different types of slides‚ each with either 20 words or 20 colored boxes‚ and recording how many words participants could read the color of‚ rather than the word itself. The colors used in this experiment were red‚ green‚ blue‚ purple and brown

William Edwards Deming was a master of quality improvement. His demonstration called the “Red Bead Experiment” was an amazingly simple‚ but effective way to highlight some problems in quality management. The example‚ which he used in many of his seminars‚ involved a batch consisting of approximately 80% white beads and 20% red beads. A group of willing workers were trained to use paddles that collected samples of beads for quality testing. The workers showed their paddles to managers who would then

Abstract: This experiment was completed with the intention of testing if two specific plants were allelopathic. Allelopathicity is defined as “They are allelon which means "of each other"‚ and pathos which means "to suffer". Allelopathy refers to the chemical inhibition of one species by another. The "inhibitory" chemical is released into the environment where it affects the development and growth of neighboring plants.” (Ref 1) Introduction: Have you ever wondered why certain plants do
