2014 The Hedwig Glass Beaker When we think of beakers we think of cool experiments we’ve done in science class in middle school to measure fluids‚ or contents‚ approximately. Sometimes we also think of beakers as cups‚ something that we drink out of or use for everyday use in the kitchen. Hundreds of years ago‚ particularly during the medieval times‚ beakers were not how we see them today. To be more specific‚ beakers‚ or Hedwig Glass beakers‚ were miraculous beakers that turned water into wine

Beach In A Beaker Introduction: The purpose of this lab is to create a heterogeneous mixture from substances commonly found at the beach. Sand and salt water will be added to the beaker to be separated. The sand will then be separated through the means of filtration. Then the salt will be separated from the water through evaporation. Theory: If the heterogeneous mixture is separated through filtration then the salt water and sand should be separated completely.A heterogeneous mixture is a mixture

SYNTHESIS OF TRANS-9-(2-PHENYLETHENYL) ANTHRACENE (A WITTIG REACTION) Introduction: The purpose of this experiment is to convert carbonyl compounds to alkenes using Wittig reaction. In this case we will be synthesizing Trans-9-(2-phenylethenyl) anthracene from benzyltriphenylphosphonium chloride and 9-anthraldehyde. We will also aim to obtaining a high percent yield and purity for the synthesis of Trans-9-(2-phenylethenyl) anthracene. The mechanism for this reaction goes thus:

MECHANISM OF AQUEOUS HUMOR FORMATION There is a constant flow of aqueous humor through the anterior segment of the eye. The aqueous is formed by the ciliary process and flows from the posterior chamber to anterior chamber through the pupil and exits the eye at the angle. The secretion of aqueous humor generates the intraocular pressure required for an optically efficient globe. The flow of aqueous provides nutrition for the avascular ocular tissues that it bathes‚ the posterior surface of the

Atomic Spectroscopy using a Constant Deviation Spectrometer with Fabry-Perot Etalon Abstract A constant deviation spectrometer with Fabry-Perot etalon has been used to investigate the various atomic emission characteristics from a Zn-Cd-Hg lamp‚ a low pressure Hg lamp and a Ne lamp. The Fabry-Perot etalon of Free Spectral Range 0.010 cm-1 was used to resolve the fringes of the Hg 546.0731nm spectral line‚ and the 594.4834nm‚ 614.3063nm‚ 640.2246nm and 650.6528nm spectral lines of the Ne lamp

Showing Respect Aileen Hernandez M. As teachers‚ usually we have to deal with a lot of things‚ such as yelling in the classroom‚ running in the halls and the lack of respect. Nowadays‚ disrespect is filling our classrooms and parents do not do anything to put a stop to the situation. As teachers or human beings we do not have to confuse respect with fear‚ because our work is to give tools and knowledge to our students‚ not frighten them. Kids are not showing any type of respect to teachers
