Potato Osmosis Biology SL - ATh INVESTIGATION “Potato Osmosis” INTRODUCTION Osmosis is a process that occurs at a cellular level that entails the spontaneous net movement of water through a semi-permeable membrane from a region of low solute concentration to an area of high solute concentration in order to equalize the level of water in each region. Involved in this process are hypotonic‚ hypertonic and isotonic solutions. A hypotonic solution is one with a lower osmotic pressure‚ indicating

Brookfield (2017) provides four lenses through which to reflect critically on our practice as a teacher: through our student’s eyes; through our colleague’s eyes; through our personal experience; and through theoretical literature. Brookfield’s four lenses are a cogent framework upon which to construct reflective practice particularly as a high school science and mathematics teacher where there

Investigation Investigate the amount of heat evolved when magnesium reacts with dilute acids. Planning What I am going to do I am going to find out how much heat is given out when magnesium reacts with a variety of dilute acids. In order to make comparisons between the acids‚ I shall use my results to work out how much heat would be given out if 1 mole of magnesium reacted with an excess of each acid. The acids I shall use are hydrochloric acid‚ sulphuric acid‚ nitric acid and ethanoic acid

ABSTRACT Title of Thesis: FREE-SPACE OPTICAL COMMUNICAITONS THROUGH A FOREST CANOPY Clinton Lee Edwards‚ Master of Science‚ 2004 Thesis Directed By: Professor Christopher C. Davis‚ Department of Electrical and Computer Engineering This paper models the effects of the leaves of mature broadleaf trees on air-to-ground free-space optical (FSO) communication systems operating through the leaf canopy. Ecological radiation transfer models are considered and the concept of Leaf Area Index

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

‘Optical Distortion‚ Inc.’ Case Study December 02‚ 2013 Situation Executive Summary: Optical Distortion Inc. is a single product company that produces contact lenses for chickens. ODI believes that the use of contact lenses for chickens is a superior solution for poultry farms relative to the current alternative manners that farmers use to prevent cannibalism among their chickens – something that is the cause of mortality rates of up to 25% on some farms. Given the fact that

Lower mortality‚ no egg loss‚ labor in efficiency and feeding in the trough with at least 3/8” deep are the main points to reduce the cost. 1)‚ Debeaking reduces mortality from 25% to 9%. However‚ a test reveals that ODI lower the mortality to an average of 4.5%. The purchase cost per hen is $2.4. So‚ the

1. Introduction Blu-ray is a new optical disc standard based on the use of a blue laser rather than the red laser of today’s DVD players. The standard‚ developed collaboratively by Hitachi‚ LG‚ Matsushita (Panasonic)‚ Pioneer‚ Philips‚ Samsung‚ Sharp‚ Sony‚ and Thomson‚ threatens to make current DVD players obsolete. It is not clear whether new Blu-ray players might include both kinds of lasers in order to be able to read current CD and DVD formats. The new standard‚ developed jointly
