The Floating Egg Problem Introduction: This experiment was constructed to aid in the practice of using the volumetric system and the glassware that determines volume. Volumetric glassware contains an accurate amount of liquid and also measures the volume accurately. Density is a measure of how much matter takes up a certain amount of space or volume. The more matter you can pack into a certain space‚ the denser it is. Although we often confused the two‚ density and weight are actually two

Why must laboratory procedures and practices be clearly communicated? By Christina Lishman INTRODUCTION: Laboratory procedures and practices are a set of guidelines which provide a clear guide on how to plan‚ perform‚ record and report all experiments safely so that human health isn’t harmed. By clearly communicating these procedures‚ it ensures quality‚ reliability and safety of the experimental activities being carried out. Laboratory procedures and practices must be clearly communicated so that

accuracy of scientific glassware. I figured the smaller the glassware the more accurate the measurements would be. Which when we were preforming the experiment proved my theory. As the glassware got smaller the easier it was to get the accurate amount of water into the glassware. We went from a big flask to a small beaker to an even smaller pipette. We used a scale to get the appropriate weight of the water in the different beakers. To test this‚ we weighed multiple glassware and different sized

Role of Laboratory in Clinical Trials Laboratory data forms the backbone of all the clinical trials. Hence it is important to have good laboratory support and interaction with the laboratory in all the clinical trials. Clinical trials typically include two kinds of activity a) evaluation and validation of new clinical laboratory testing systems or b) laboratory evaluation of patients subjected to new clinical products or protocols‚ particularly those related to new drug development

Why does colour leak out of cooked beetroot? Introduction When cooking a beetroot you are recommended not to remove the outer skin and not to cut off the entire stalk if you do not want the red dye in the cooking water. Beetroot contains a red pigment called betalain‚ which is in the cell vacuole. Normally the betalain stays inside the cell‚ however when the cell is exposed to extreme temperatures they leak out. The reason why they leak out is because of the cell membrane structure. When the
