Name: Section: SP1L-17 Date: 2/26/11 Coulomb’s Law: What is the charge on a charged pith ball? Experimental Determination of the Electrostatic Force acting between two charged pith balls Equipment: a pvc pipe and fur or wool‚ a metric ruler‚ a protractor‚ two pith balls on a stand as in figure 1. Your teacher will tell you the mass of your pith balls. Procedure: Make sure the strings of your two pith balls are untangled as in figure 1. Make sure that the pith balls are neutral by rubbing

Physics Waves Lab SL Introduction: This lab will investigate the properties of mechanical waves such as a longitudinal wave‚ focusing on the question: Does a change in the frequency of a wave result in a significant and convincing change in the speed of the wave? Hypothesis: Changing the frequency of the wave will not result in a change in speed because the wavelength will change proportionally as in theory. Student Designed Investigation Procedure/ Planning Procedure: 1. Three

The ejusdem generis rule Under this rule‚ where general words follow particular words‚ the general words are interpreted to be of the same kind as the particular words. For example‚ in the phrase ‘dogs‚ cats and other animals’‚ the particular words are ‘dogs’ and ‘cats’. The general words are ‘other animals’. Under the ejusdem generis rule the general words would be interpreted in the line with the particular words. Therefore‚ since dogs and cats are the domestic animals‚ then the general words

Purpose: To practice direct and indirect measurement Introduction: Do you think you could measure the average thickness of a sample of M&Ms without directly measuring selected M&Ms? The answer is "yes‚" and in this activity you will make direct and indirect measurements of the thickness of M&Ms. You will compare the results and evaluate the reliability of each method of measurement. Be sure to view the tutorial on the proper use of the vernier caliper. Please re-visit the information on when

2014 Empirical Analysis of Mendel’s Laws Objective: To determine if Mendel’s law of segregation and independent assortment genetic principle’s hold true by observing the genotypes of both the F1 and F2 generation of Drosophilia Melanogaster flies and applying the Chi Square analysis to the F2 offspring to see if the our results fall inside or outside statistical variation. Methods: This experiment was carried out over a five-week process. Each lab bench crossed two parental generations:

Objective: The purpose of this lab is to demonstrate that there is a linear relationship between the number of molecules that can absorb light present in a solution and the amount of light absorbed by a solution. This lab should prove that Beer’s law and the equation A=a x b x c‚ is a linear relationship. Procedure: The only deviations in the lab procedure was that the stock solution was made before arrival to the lab with 0.570 g of KMnO4 in 0.500 L. The diluted solutions and the
