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 where they are most concentrated to the side where they are less concentrated. If the concentration is equal on both sides‚ there will be no movement. 3. I hypothesize that

Material and Methods * Osmosis : -thistle funnel tube -dialysis tubing sack -saturated NaCl w/food coloring -beaker with distilled H2O The experiments begins with the construction of a simple osmometer by obtaining pre-soaked length of tubing ‚opened and tied at the end. The tube is filled with saturated NaCl solution (with added food coloring) and the thistle is inserted in the dialysis tubing. The dialysis tubing is sealed to the thistle funnel with dental floss and placed in a beaker

Although we cannot compare the horrors of the Nazi Concentration camps to the American "Relocation Centers"‚ there are many similarities. Both of the groups of victims were of the minorities‚ and these cultures were somewhat of an enemy to the leader of their country. These groups (the Japanese in America nearly two thirds of which were American citizens‚ and the Jews‚ Gypsies‚ the Poles‚ Slovaks‚ Communists and other enemies of the state in Germany and Poland‚ many of which had served the very countries

Group 4 Internal Assessment Partners: Bhavya and Katherine Research question: Does the concentration (mol dm3) of sulphur dioxide in wine rise or fall when exposed to air for different time periods (0‚ 75‚150‚225‚ 300 minutes)? Purpose: Many adults enjoy the consumption of wine but are not aware of the different preservatives and chemicals that are added to the drink. Sulphur Dioxide‚ which is added to many food products including wine because it acts as a reductant‚ is ‘well known as a poisonous

We had started our experiment by learning about the change in the earth and what it does to the concentration in the oceans water. When global changes occur‚ they don’t only change that one thing it changes many things. Such as concentration in the water. For example‚ when heavy machinery or facilities burn fossil fuels‚ which releases more carbon dioxide in the air‚ the ocean sucks it up and the acidity in the water completely changes even if it goes up by .1 or .2 percent it’s still a lot and will

The effect of nutrient concentration on duckweed growth Gina Neonakis Biology 203L:11 Biology 203:10 November 14‚ 2011 Abstract Lemna minor‚ or duckweed‚ is a small plant that floats on the surface of stagnant water that is usually rich in nutrients. Phosphorus is an important macronutrient in the growth of aquatic plants. We tested the effect of phosphorus on duckweed population growth using a control medium rich in nutrients and compared it to the population growth in a medium that lacked

The aim of this experiment was to calculate the concentration of an unknown solution of Sodium Hydroxide (NaOH) by titrating it with Hydrochloric Acid (HCl) and to identify any possible sources of error. A colour change from pink to yellow signified the end of each individual titre as the NaOH had been neutralised. Experimental: Method: Firstly two solutions were prepared to show the colour of the Phenol Red indicator in acid and alkaline conditions. These colours were then used to determine the

they depicted true thoughts of Jewish captives during this time period. Though most of the novel described life in concentration camps‚ three lines truly portray the feelings‚ emotions and mindset Jews had under the Nazi regime. "Never shall I forget those moments that murdered my God and my soul and turned my dreams to ashes..." (Wiesel 34). This line shows the impact concentration camps had on Wiesel’s life‚ soul‚ and belief. As a child‚ Wiesel became Godless for he saw no God of his would allow
