The issue of English language learners (ELL) and their rights to an education has been a major topic of debate for many years. Should ELL students be taught in their first language? Will they learn English‚ or should they be put into English speaking classes? That has been the topic of discussion amongst educators. Which method is better for the student? The arguments continue and many states and school districts have made a decision on what to do. One state in particular had a serious ELL problem

A small amount of the unknown (approximately the tip of the spatula was used for all the pigments) was added into each clean dry test tube. For the first test 1 mL of 3 M of HNO3 was added. As soon as the acid came into with the solid‚ the pigment was observed to dissolve while also turning the solution into a pale clear colour. The same amount was used for the HCl reagent. As soon as the acid touched the pigment it yielded in a clear solution (solid dissolved after a few shakes). When the KI was

RECRYSTALLIZATION Group Medical Technology Organic Chemistry Laboratory ABSTRACT Recrystallization is one of the simplest and most widely used technique for purifying organic solids through the differences in solubility at different temperatures. It is also the process in which the solid to be crystallized is dissolved to either a hot solvent or a hot solvent mixture and is cooled in a solution.In this experiment‚ acetanilide‚ the crude product of acetylation of aniline and acetic anhydride

A formal report is a methodical presentation of a subject or an action which includes summaries of important points as well as appendices of tangential and secondary points. In simple words‚ a formal report is used to formally document the outcomes of an experiment‚ a design or an information which can provide the readers a clear understanding of why and how the experiment or action is done and what it concludes. Apart from readers understanding‚ a formal report is also prepared in order to record

Lab #5-Enzymes NAME DATE LAB PERIOD Introduction Enzymes are proteins‚ though highly complex and diverse‚ they serve one basic function; to work as an organic catalyst. A catalyst‚ as defined by Merriam-Webster dictionary‚ is a substance that enables a chemical reaction to proceed at a usually faster rate ("Catalyst-Definition and more."). They function by reducing the activation energy‚ or energy required to start a reaction. The way enzymatic reaction works cannot be altered‚ but the
