increase the reaction. As I increase the surface area of the potato the gas given off from the reaction will increase. Therefore to sum things up‚ my hypothesis is when the Independent variable increases so will the dependant variable. Independent variable: - Surface area of potato Dependant variable: - Gas Controlled variable: - Equal size of potatoes used - Using measuring cylinder Equipment used: - Gas collecting kit - Potato - Stop watch - Test tube - Distilled water - Hydrogen

“The first essential for the child’s development is concentration. It lays the whole basis for his character and social behavior‚ he must find out how to concentrate‚ and for this he needs things to concentrate upon…” The Absorbent Mind‚ Chapter 22 Discuss how the Montessori Education helps to develop a child’s concentration and helps the child in his social development. In order to accomplish any task you need to be able to concentrate

Activity Over Different Concentrations and Effects The goals of this experiment were to examine the effectively of enzymes on samples of different enzyme concentrations and substrate concentrations. In addition‚ the experiment tested how effective enzymes are on samples of pH levels and temperature levels. A. Effect of Enzyme Concentration Hypothesis: With half as much enzyme concentration then the reaction rate will be half as much than when the enzyme concentration is equal to the substrate

Construction of a Standard Curve for the Determination of Protein Concentration 09/13/12 PCB 3023-007 Results Figure1: Standard curve. This graph was constructed from the fixed amounts of Bovine Serum Albumin (BSA). Varying amounts of BSA at a concentration of .5µ/µl were mixed with the water and 1mL of coomassie dye. The equation y=0.0259x +0.0511 represents the best fit line for a data set taken from µg of protein equals two to ten µg. Optical density (OD) was surveyed using a Mach

Before I came to the concentration camp‚ it was easy to be with your family but I have been in the concentration came for almost 3 months. In the times I been in the camp‚ I met my best friend‚ Graciela. Ever since I been in the concentration camp‚ life has been hard for everyone. In the mornings‚ you are awakened by the kapos in the 4 in the morning where you must raise and find your shoes to work. If someone stole your shoes‚ the person who took them often means they are send to death

Null hypothesis The concentration of sucrose in the soil will not affect the growth of the common wheat seeds. Alternative hypothesis The concentration of sucrose in the soil will affect by slowing down the growth of the common wheat (Triticum aestivum) seeds. The sucrose solution (sucrose mixed with water) added to the soil makes high concentration outside the common wheat cells and the common wheat cells become an area of low concentration. Because the osmosis is reversed‚ the

What happens? For many reactions involving liquids or gases‚ increasing the concentration of the reactants increases the rate of reaction. In a few cases‚ increasing the concentration of one of the reactants may have little noticeable effect of the rate. These cases are discussed and explained further down this page. Don’t assume that if you double the concentration of one of the reactants that you will double the rate of the reaction. It may happen like that‚ but the relationship may well

ruthless place for Jews in concentration camps. A large number of people who got put into concentration camps died either from being gassed or being worked to death. The bodies of those Jews would either be cremated or buried in mass graves‚ or not even buried at all. Hitler thought that the loss of WWI was the Jews fault‚ thus Hitler started the mass murder and Genocide of all Jewish people in Germany and Central Europe. There were approximately 20‚000 German concentration camps for WWII. There were

Discuss the effects of increased concentration in transport markets. Concentration ratio refers to the market share of the largest firms in an industry. For example‚ a 5 firm concentration ratio of 65% means that the 5 largest firms have more 65% of market sales. If the concentration ratio increased‚ then 1 or 2 firms may start to dominate the market and the firms will be able to exercise Monopoly power. (in UK legal definition of a monopoly is a firm with more than 25%) This is likely to cause many
