Laboratory Report: Observing Bacteria Purpose: Is to gain knowledge on how to use a microscope and oil immersion lens while observing prepared bacterial slides and also to prepare slides for observable bacteria culture from yogart. Procedure: Exercise 1: Using the Microscope - Viewing Prepared Slides I started out by reading and reviewed the science lab safety reinforcement Agreement and the instruction to oil immersion lens. After setting up my lab station I view the six prepared slides

Carlie Haeffner Qualitative Analysis March 20‚ 2015 The purpose of this lab is to identify unknown ions in a solution by using a type of chemical reaction called precipitate reactions. The key to finding which ions are present in a solution is to form a precipitate which makes the ions “come out” in a reaction (McNeil‚ 2013-2014). Water is used in these experiments to act as a solvent. Since water is a polar molecule‚ the slightly positive and negative charges will sometimes pull apart molecules

There are times in one’s life that they can look back upon and be truly proud of themselves. Laying the wreath at the Tomb of The Unknown Soldier is one of those opportunities. Not only does one get to honor all who have fought and died for this country‚ but they get to do it in a way that is remembered and cherished for the rest of their lives. And honoring these soldiers allows one to do something greater than just in their town‚ something greater than in their school‚ and something so great‚ that

Similarities and Differences Bacteria and archaea both share the fact that they are single-celled prokaryotic microorganisms that lack membrane enclosed nuclei. It has been discovered that the two typically can be found to have the same size and shape as one another. “They are both found occurring as rods‚ cocci‚ spirals‚ plates‚ coiled etc.” ("Archaea vs. Bacteria‚" n.d.). Both organisms use the flagella to swim and also reproduce by means of binary fission. On the surface these similarities can

Adventures in the Unknown Interior of America is a tale of epic proportions worthy of The Odyssey. The only difference being that this tale is true. Written by Álvar Núñez Cabeza de Vaca‚ Adventures in the Unknown Interior of America details the events of Cabeza de Vaca’s eight-year trip from Spain to the New World. It becomes quite clear though his journey that Cabeza de Vaca changes into a completely different man than he was when he set out from Spain in the name of the king‚ and God. Cabeza

Determining the Unknown Concentration of NaHCO3 (aq) Through Titration Introduction Titration is the accurate addition of a titrant- solution in a burette- into a measured volume of a sample (Kessel‚ 2003). There are many different types of titration‚ such as acid-base reaction‚ redox reactions‚ precipitation reaction and more (Dohrman). In this lab an acid base titration will be explored. In an acid-base titration‚ the concentration of an acid or base is unknown and is determined by the adding
