The Introduction Abstract Through examining the simple harmonic motion of a mass hanging on a spring‚ three investigations were conducted in the experiment. The experiments include the relation between the period in oscillations and mass‚ and figuring out if the period vs. mass graph should go through the origin and lastly‚ finding the mass needed to create a one second timer. It was investigated by placing a motion detector under a spring that was attached to a clamp which was attached to a retort

SIMPLE REACTION TIME Objective To acquaint the students in reading laboratory primers and organize data into summaries and graphs. Introduction Apparatus Required Stopwatch‚ Meter Stick. Procedure Part – I Select your laboratory partner and toss a coin to determine who will be E and S. S holds the timer with preferred time. At E’s go signal‚ S starts the timer and must talk of free associate while making an estimate of 12 second interval. E records the estimate in Table I. S should not see the face

Simple Stimulus Learning In the following analysis of various forms of simple stimulus learning‚ the concept of habituation‚ including many examples will be studied and explained. Three factors that affect perceptual learning will be analyzed. Those factors include presenting contrasting stimuli‚ transfer from easy to difficult stimuli‚ and attention and feedback. The following effects of stimulus exposure will be examined: Preference for familiar stimuli‚ priming facilitation‚ and potentiated

compounds based on differences in their boiling points. The experiment is divided into two parts: simple distillation‚ an easy set-up where a solution or a mixture of substances with different volatility is separated through exposure heat; and fractional distillation‚ which under goes a series of evaporation and condensation process to purify more complex mixtures. Raoult and Dalton Law are the two principles involving with this experiment. The former states that the vapor pressure of a solvent above

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

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

cell from the exterior and regulate the movement of substances in and out of the cell. Diffusion is how substances more in and out of the cell. There are several types of diffusion‚ but for the purposes of this lab‚ we will be focused on simple and osmosis. Simple diffusion and osmosis are vital for the diffusion of water and maintaining homeostasis. Homeostasis is the ability to maintain equilibrium and keep the organism alive. For example‚ if a cell is placed in a hypotonic solution there is more

Experiment 2: Microscopy & Simple Staining September 30‚ 2013 General microbiology laboratory The invention of the microscope has opened up a whole new dimension in science. By using microscopes scientists were able to discover the existence of microorganisms‚ study the structure of cells‚ and see the smallest parts of plants‚ animals‚ and fungi. Today‚ the microscope is still a commonly used tool to diagnose illness in hospitals and clinics all over the world (1)

Simple Harmonic Motion Ethan Albers Case Western Reserve University‚ Department of Physics Cleveland‚ OH 44106 Abstract: In this lab‚ my partner and I observed oscillations that were translational and rotational. The two forms we studied must have a form of a restoring force that is proportional to the displacement of the object from its point of equilibrium. This produces the harmonic motion which this lab wants. At small and big amplitudes we measured/observed the translational oscillation

Biotechnology‚ Mapua Institute of Technology ABSTRACT In this experiment‚ solubility class of various organic compounds are to be determined. The main objective of the experiment is to identify an unknown compound through the use of preliminary tests such as examination of physical state‚ color‚ odor‚ and ignition properties. Also‚ solubility tests were used to further examine an unknown compound’s solubility class. In this experiment‚ the apparatus used are micro test tubes and droppers for mixing
