Adsorption Experiment This paper will be discussion the adsorption experiment conducted in Dr.O lab class. This paper will cover what Chitin/Chitson are but before explaining what these are it is best to get an understanding of what adsorption‚ absorption and sorption are. Adsorption is the accumulation of gases‚ liquids‚ or solutes on the surface of a solid or liquid. This binding is very weak. Almost anything such as fluids that dissolves can break the binding of the molecules. In addition adsorption

The effect of alcohol concentration on the cell membrane Abstract: In this experiment I found out that as the concentration of the alcohol was increased so did the colour intensity of the solution. This is because the higher concentration of ethanol‚ results in more damage done to the cell membrane‚ resulting in leakage of red pigment from the cell. If the membrane is damaged more‚ more red pigment will leak out of the membrane and into the ethanol. Hypothesis: The higher the concentration

- Quasi Experimental Design: If the researcher lacks control over the assignment of participants to conditions and does not manipulate the causal variable of interest‚ the design is quasi experimental. o Quasi Experiments do not have internal validity because participants are not randomly assigned to conditions and the researcher may have no control over the independent variable. - Basic Confounds in Quasi Experimental Design are : o History o Maturation (Emotional‚ Physical & Psychological)

ABSTRACT The Stroop experiment focuses on the interference of a person’s reaction time on a given task. Certain tasks can be performed with more accuracy due to the fact that our brain becomes conditioned to react automatically after exposure of the stimuli. In this particular experiment‚ eight-teen college students underwent the Stroop experiment in individualized laboratory rooms. Four students were male and fourteen were females. The experiment helped us examine the horse race model
