SEEDLING GROWTH EXPERIMENT GEOS170C1 Fall 2014 Workshop 1 09/10/2014 Hypothesis: Electric energy can speed up the growth rate of plants. The access of an electric current can modifies the physic-chemical properties of the seed. It can charge the mitochondria‚ and intensifies other metabolic processes of the seed. This can achieve the purpose of sterilization‚ and enhanced the ability of absorbing water and oxygen. Prediction: The seeds that have been energized will sprout early than the control

Effects of Allelopathy on Plants Dates experiment was conducted: Purpose: The purpose of this experiment is to design a controlled experiment to see if a plant could survive living in eucalyptus tea. Allelopathy is when a plant gives off a bio-chemical that kills that plants around it‚ such as eucalyptus trees‚ black walnut trees‚ etc. My class went to the a eucalyptus grove and observed the eucalyptus trees. We noticed that there was a small circle around the tree that had nothing growing

The milgram experiment. The three people involved were: the one running the experiment‚ the subject of the experiment a volunteer‚ and a person pretending to be a volunteer. These three persons fill three distinct roles: the Experimenter an authoritative role‚ the Teacher a role intended to obey the orders of the Experimenter‚ and the Learner the recipient of stimulus from the Teacher. The subject and the actor both drew slips of paper to determine their roles‚ but unknown to the subject‚ both slips

We can be assured that each replication of the experiment with all 20 participants went almost identically to one another‚ due to the predetermined speech given and replicated setup of the classroom and the positioning of each of the experimenters and participants. There was high internal validity within experiment‚ meaning high levels of control due to precise control of independent

Employee Recognition and Performance: A Field Experiment∗ Christiane Bradler† Robert Dur‡ Susanne Neckermann§ Arjan Non¶ ‚ ‚ ‚ January 2013 Abstract This paper reports the results from a natural field experiment designed to investigate the causal effect of public recognition on employee performance. More than 300 employees worked on a three-hour data-entry task‚ where we randomized the unannounced provision of recognition after two hours of work. We find that recognition increases subsequent performance

A. Stanford Prison Experiment- In this experiment‚ students volunteered to be a part of a psychology experiment that was being conducted at Stanford College. Because of the situation around them‚ they conformed to the environment‚ even though it was only a simple experiment in a Stanford hallway. Embarrassed and yet impressed‚ the experimenters stated this‚ “The negative‚ anti-social reactions observed were not the product of an environment created by combining a collection of deviant personalities

Levels of Processing and memory The aim of the experiment is to investigate (a) whether level of processing (IV1) affects memory for words‚ (b) whether the intention to learn (IV2) has an effect upon memory and whether an effect of level of processing on memory for words is dependent upon intentionality of learning (IV1xIV2)‚ i.e. Is there an interaction effect? Levels of Processing is an influential theory of memory proposed by Craik and Lockhart (1972) which rejected the idea of the dual store

This assignment called for me to pick three out of four sensory experiments to conduct and then record my reaction to each experiment. The three experiments I chose to conduct are number one- the sandpaper experiment‚ number three- the index cards and flashlight experiment and number four- the water in bowls experiment. While conducting each of these three experiments I was surprised by the results of each of them. Experiment Number One: I rubbed my finger on the piece of coarse sandpaper and

Daphnia Experiment Report 1. Introduction Caffeine is found in many plant species‚ where it acts as a natural pesticide. It is found most commonly in cocoa‚ tea and coffee‚ but is also artificially added to some soft drinks such as cola to act as a flavour enhancer. When consumed by humans‚ caffeine works as a stimulant causing amounts of released neurotransmitters to be increased. High use of caffeine has been related with raised blood pressure‚ restlessness‚ insomnia and anxiety which‚ in
