Osmosis Lab Report The essential focus of the experiment was to acquire data for the mass change resulting from osmosis in order to determine the carbohydrate solution of the carrot cells. The carrots were a vegetable used within the experiment with a carbohydrate solution around .5 M. The hypothesis is if there are carrots in different carbohydrate solutions then there will be a percent change in mass. The carrots have large vacuoles that hold water‚ this allows the mass to increase when the hypertonic

Parachute experiment Aim: The aim was to find the effect of holes on a parachute‚ varying their size and number. Hypothesis: 1. By increasing the number of holes‚ the time it will take to the parachute to reach the ground will be longer and its flight will be more balanced. 2. By increasing the size of the hole on the parachute‚ the time it will take to the parachute to reach the ground will be shorter and its flight will be less balanced. Apparatus: - garbage bag (squared shape

A 2007 study finds that discharge of untreated sewage is the single most important cause for pollution of surface and ground water in India. There is a large gap between generation and treatment of domestic waste water in India. The problem is not only that India lacks sufficient treatment capacity but also that the sewage treatment plants that exist do not operate and are not maintained.[1] The majority of the government-owned sewage treatment plants remain closed most of the time due to improper

| Desalinization of Water | | | Sara Reed‚ Myp2 | | Chemistry | | * Our world consists of 70% of water‚ from which‚ only 2.5% is fresh water‚ and 1% is drinkable water. Because of this low drinkable water rate‚ desalinization is a very important process which will help us provide a higher percentage rate. * Desalination is a process in which salt water is turned into fresh water‚ by extracting its water and minerals. Desalination is used on many ships and submarines
