Potato Osmosis Introduction: A shipwrecked sailor is stranded on a small desert island with no fresh water to drink. They know they could last without food for up to a month‚ but if they didn’t have water to drink they will be dead within a week. Hoping to postpone the inevitable‚ their thirst drives them to drink the salty seawater. They are dead in two days. Why do you think drinking seawater killed the sailor faster than not drinking any water at all? Today we explore the cause of the sailor’s

Desalination of Seawater Project Paper The main concept of this Desalination process is reverse osmosis‚ but we will get into that later. Right now what is probably running through your head is what exactly is desalination. To put it simply desalination is the process to make seawater or otherwise undrinkable water safe to consume. This can be accomplished through a variety of methods such as the simplest but one of the ones that requires a lot of money would be distillation. Distillation is commonly

Not all of the learning you do will take place on a course or a lecture‚ or through the latest textbook. A very large amount of your learning will take place while doing your job. Everything you do at work is part of a process of learning. Even regular tasks are likely to be important for learning because there is always something new each time you do them. A simple task like taking someone a hot drink may result in a lesson – for example‚ you may find that the person tells you they do

warmer‚ this may have sped the diffusion process because the molecules would have been moving faster. If the water was freezing‚ this may have slowed the diffusion process because the molecules may have been moving slower. Part B: Title: The effect of salt concentration on osmosis in potato. Introduction: 1. The purpose of doing this lab is to observe the effects of various solute concentrations on osmosis in a potato. 2. During osmosis‚ water moves from the side of the membrane

Demonstrate How an Omega/Rolex watch are made Joliena Hackler May 3‚ 2013 Speech General Purpose- To demonstrate how an Omega Watch is made Intro: Today I’m going to demonstrate how the inside of an Omega watch functions‚ the Co-Axial Chronometer-The organ determines the frequency of the movement through regular Oscillators. The Co-Axial Escapement wheel & pallet fork interrupt the rotation of the gear train & send impulses to the organ gear train transmits energy to the Co-Axial

Lab One – Diffusion and Osmosis SECTION ONE: Methods Lab 1 – Diffusion and Osmosis can be broken down into four parts (A‚ B‚ C‚ and D). Lab 1A – Diffusion In this exercise‚ we tested diffusion through dialysis tubing. This was done through a demo with the teacher‚ rather than individually in groups. First‚ a piece of 2.5cm dialysis tubing was obtained. Then one end was folded and clipped securely so that a solution poured into the bag would not leak out. Next‚ the other side of the bag was
