Introduction In this lab we had to design a system that would test if changing the mass‚ angle of release and length would have any effect on the period of a pendulum. Hypothesis As the length‚ mass and angle of release change‚ the period (T) will change for each one of these factors.

Tetraphenylcylopentadienone Post-Lab Report Purpose- This experiment illustrates the use of adol condensation for the synthesis of a five-membered carbocylic ring. It is also a good demonstration of the impact extended conjugation has on the absorption of visible light. The reactants are bright yellow in color while the products are a very deep purple color appearing almost black. Introduction- The synthesis of Tetraphanylcyclopentadienone was a further example of the adol condensation reaction

Gene Choi BIOS 101 By Wednesday 3 P.M. TA: Michelle Lamont Medieval Science Lab Report Introduction Medieval and early renaissance scholars believed in three scientific paradigms: alchemy‚ astrology‚ and folk belief. These three scientific paradigms are produced without extremely thorough testing‚ yet they still can produce accurate predictions. This means that the medieval science not only allowed beginning with scientific method‚ but also beginning with superstition and theories. One of the three

component‚ and so on‚ until it reaches the source again. In contrast‚ a parallel circuit is a circuit in which the has more than one resistor and has multiple paths to move along. The main purpose of this lab was to prove the laws of Ohm and Kirchhoff. On another note‚ being able to take part in this lab taught my partner and I the fundamental skills of constructing series and parallel circuit and using a multimeter to calculate the current and voltage of a circuit. I believe that if we only have the

Planarian Lab Report Hanna Klein Bishop Fenwick High School Planarian Lab Report Introduction Planarian worms are free-living flatworms that are not parasitic. Planarians have a three-cavity digestive system. Planarians are usually either carnivorous or scavengers. Planarians may eat other living‚ as well as dead‚ invertebrates‚ detritus or decaying organic matter. Planarians do not realize that are eating a lot‚ and can over eat resulting in death. Most planarians are freshwater forms that can

Bacterial Transformation Lab Report Backround: The plasmid pGLO contains an antibiotic-resistance gene‚ ampR‚ and the GFP gene is regulated by the control region of the ara operon. Ampicillin is an antibiotic that kills E. coli‚ so if E. coli‚ so if E. coli cells contain the ampicillin-resistance gene‚ the cells can survive exposure to ampicillin since the ampicillin-resistance gene encodes an enzyme that inactivates the antibiotic. Thus‚ transformed E. coli cells containing ampicillin-resistance

Unknown Lab Report Dr. Nathan Cahoone Microbiology 204 December 9‚ 2010 Introduction There are many reasons for knowing the identity of microorganisms. The study and test was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium which I was using unknown #25. Results Unknown #25 had the following morphology on a streak plate: medium sized butyrous cream colored colony. Gram-staining was utilized

Enzyme Catalysis Lab: Laboratory Write Up Problem/Question: What happens to the amounts of gas produced in a catalyzed reaction of Hydrogen Peroxide when the catalyst is mixed with an acid? Theory/Hypothesis: In this experiment the researcher and their team will be performing tests on a catalyst (proteins found in potato) to see what will happen when the catalyst in a Hydrogen Peroxide reaction is treated with an acid before the reaction occurs. The researcher hypothesizes that the after treating

Introduction: To achieve genetic experiments with haploid organisms‚ genetic strains of different genotypes must be crossed from one another. Following fertilization and meiosis‚ the meiotic products can be analyzed as the ascomycete fungus‚ Sordaria fimicola. Sordaria can be used as a model to study meiotic segregation. The trait followed was the ascospore color. Ascospore color is a single gene trait therefore it is easily observed under a light microspore. Which allele is dominant is very tough
