Exploration Research Question What is the effect of different concentrations of sucrose in a solution on the mass and surface area of a beetroot (Beta Vulgaris) piece? Background The membrane consists of a phospholipid bilayer which is semi permeable. Osmosis is the passive movement of water molecules from an area of high water potential to an area of low water potential across a semi-permeable membrane. It is easy for water molecules to pass through this membrane however solutes that are big in

Effervescence Experiments 6th grade lesson plan Tim Braunsdorf and Doug Martin NISMEC July 2010 Standard/Indicator 12. Investigate how the temperature and acidity of a solution influences the reaction rates‚ such as those involved in food spoilage. Objective Students will be able to describe the effects of the temperature of a solution on reaction rates and support their thinking using data from the investigation. Guiding Question How does the temperature of a solution affect a

Microscope * Head/Body houses the optical parts in the upper part of the microscope * Base of the microscope supports the microscope and houses the illuminator * Arm connects to the base and supports the microscope head. It is also used to carry the microscope. * Eyepiece or Ocular is what you look through at the top of the microscope. Typically‚ standard eyepieces have a magnifying power of 10x. Optional eyepieces of varying powers are available‚ typically from 5x-30x. * Eyepiece

Introduction The main purpose of root canal treatment is the elimination of microorganism from root canal system (1‚2). Microorganisms and their byproducts are regarded as the primary etiological factors of periapical diseases and pulpal necrosis (3‚4‚5). Microbial reduction obtained by mechanical instrumentation‚ irrigation‚ using intracanal medicaments and adequate filling of root canal (6). Failure of the root canal treatment is the result of persisting microorgansims in the root canal system

Food is the basic unit of life. There are many types of food‚ but not all are healthy. The argument of eating a healthier diet to get better health benefit is what the society is willing to get. Joseph pace is arguing and persuading people that the correct diet is vegetarian diet to have better health benefits‚ stronger agriculture and resource use that benefits the animal rights. Meanwhile Alan Herscovici is arguing how a diet which includes meat is healthier choice and brings light to the myth

Motion in a Viscous Medium Aim The aim of this experiment is to measure the terminal velocity of spherical beads falling under gravity in a liquid determine‚ and hence determine its viscosity using Stoke’s law. Introduction When a stationary solid object is complete or partially immersed in a fluid‚ it experiences an upthrust or buoyant force. According to Archimedes’ principle‚ this buoyant force B is given by where ρ is the density of the fluid‚ Vs is the immersed volume of the
