Accuracy and Precision of Spitballs Problem: How far will the spitballs land from the target when shot at different distances? How far will the spitballs be from each other when shot from different distances? Hypothesis: I believe that the accuracy will be similar when shot at the same distance but the closer you get to the target the more accurate it will be. For precision I think they should not be that far apart because you should shoot them relatively close. Materials: The materials

Basically‚ this extended essay will be able to prove the mathematical accuracy of AMC’s TV series The Walking Dead. To do this‚ certain aspects of the series will be analyzed. Firstly‚ the lifespan of a zombie. As viewers of the series may know‚ 3 years have passed since the zombie apocalypse started‚ and these don’t sleep‚ they are in constant movement‚ and don’t eat each other. If that is the case‚ then how are zombies alive? Certain aspects will be analyzed‚ such as the lack of intake of nutrients

Introduction Glucose is very important in our daily lives. It gives us energy to carry out all of our activities. Cells in our bodies need glucose to respire and in the process release the energy we need. Glucose is also a type of carbohydrate. It has a chemical formula of C6H12O6 and is a monosaccharide reducing sugar (Kolej Mara Banting – Students’ Handbook for Biology HL Year 1). It is the simplest form of carbohydrate. In this experiment‚ sulphuric acid‚ H2SO4 and potassium permanganate

Estimating Osmolarity of Plant Cells Criteria Assessed: DCP Introduction In this experiment you will be estimating the osmolarity of potato cells by finding their change in weight in solutions of known molarity. The object is to find the molarity where the mass does not change. No net change in weight indicates that there has been no net gain or loss of water. This is a means of indirectly finding the osmolarity of the cells themselves. Apparatus 1 large potato Petri dish 7 x 250 ml beakers

Pipetting‚ weighing‚ accuracy and plotting Introduction The aim of this experiment was to determine the density of water and‚ of unknown solutions‚ by being as accurate as possible‚ by pipetting and weighing the solutions. Density if defined as “The mass per unit volume of substance; common unitg cm-3” (Lewis. R and Evans. W.‚ 2011). As the density is an intensive property of all matter it depends on temperature and pressure. “The density of a mixture may also depend on its composition” (Nedelsky

Historical Analysis of Noah Emma O’Neil CHW3M0-B Ms. Kuypers May 16th‚ 2014 Noah It was once said “if you don’t remember history accurately‚ how can you learn?” Accurate portrayals of historical Hollywood movies are more or less unheard of. These movies show a false representation of what occurred in the time period‚ making it hard for people to know fact from fiction about the past. The movie Noah‚ despite its best efforts‚ is not historically accurate because it does not

Task-based learning (TBL) is an approach which concentrates more on carrying out tasks (solving puzzles‚ writing projects‚ investigating topics and so on) than on graded structures and vocabulary. Task-Based Learning (methodology plus) Contributed by Mark McKinnon and Nicky Rigby What is TBL? How often do we as teachers ask our students to do something in class which they would do in everyday life using their own language? Probably not often enough. If we can

Precision describes the closeness of results that have been obtained in exactly the same way while accuracy indicates the closeness of the measurement to its true value. This experiment was used to determine the accuracy and precision of different volumetric measuring devices‚ as well as determining the density of an unknown metal. This lab was to help understand the application to volumetric measurements. Part 1: First‚ the next-to-smallest beaker was cleaned‚ dried‚ and weighed on the scale
