Title of Practical: The Effect of Concentration on Reaction Rate Aim: To use a simple reaction between sodium thiosulphate and hydrochloric acid to discover concentration this determines how fast chemical reactions occur. Independent Variable: Concentration of hydrochloric acid (%) Dependent Variable: Time taken for chemical reaction to take place (sec) Hypothesis: My prediction is that the increased concentration of the thiosulfate will in turn lead to an increase in the rate of reaction

looking at the effects of alcohol consumption by college/university students‚ how it impairs the functioning of the human brain‚ the cognitive process of information and personality. I will be focusing on the parts of the brain that alcohol has effects on such as; cerebral cortex and the frontal lobes‚ the cerebellum‚ the hippocampus‚ the medulla and the hypothalamus‚ as well as how it affects personality (behavior) and intelligence and cognition. According to Clarren & Smith (1978) alcohol is depressant

Understanding ion permeability is vital to knowing how it establishes a membrane potential‚ and how it eventually leads to the contraction of muscle cells. This was done using crayfish tail muscles. Lateral and medial tail muscles from the tail of a crayfish were excised. These muscles were then placed into solutions with different types of ion concentrations. Usage of different ion concentrations was necessary in practicing how to measure resting membrane potentials accurately. Measurements with
