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

Physics Lab Report Format General Remarks: Writing a lab report is the only way your TA will know what you have done during the lab and how well you have understood the process and the results. Part of your lab experience should be learning how to organize and present your work in a scientific way. There is no framework that can be used as a “one size fits all”‚ therefore this sample lab report should only be used as an example. Any lab report should have the following features:

order to determine whether or not simple harmonic motion follows Hooke’s law. The experiment consisted of two parts‚ the first part was done with springs hanging weights as well as the pulling down of a string attached to the spring for both individual and two springs. The second part was done with a collision cart and springs attached on both ends of the cart. The data obtained supported that simple harmonic motion obeys Hooke’s law as the spring value constants were all positive and the graphs displayed

so that it lands safely. Background Obviously I built this device with some prior knowledge to physics and how to make this device successful. I have learned several equations about force‚ work‚ power‚ height‚ speed‚ velocity and a lot more. So with force‚ f=ma‚ then I can easily discern what the force of the egg will be. Also‚ since I know all of these things‚ than I can figure out all of the physics with just the equations. Also I learned‚ with these things‚ that if the force of the egg doesn’t

Gas Laws Lab Introduction: The four basic physical properties of a gas sample are pressure‚ volume‚ temperature‚ and number of moles. The volume simply indicates the volume of the container since a gas will take up all space available to it. The temperature indicates the average kinetic energy of the gas particles. For gases‚ the temperature must be converted to the Kelvin unit. The pressure of the gas indicates the number of collisions with each other and the wall of the container. The number
