Experiment 1: Viscosity of Liquids Victoria Kulczak Lab Partners: Laina Maines & Heidi Osterman Date of Lab: 2/21/11 Due Date: 2/28/11 Abstract: The goal of this experiment was to determine the viscosity of given liquids. Two different methods were employed‚ the first measures time of flow of several methanol-water solutions‚ from point A to point B. The second method involves dropping a foreign object‚ in this case a sphere‚ into a cylinder of glycerol and measuring the time it takes for it to

investigate the effects of temperature on the growth rate pine seedlings. Experiment 1 A batch of 60 pine seedlings (Batch I) was grown in a greenhouse under controlled temperatures. Ten plants were grown at each of six temperatures from 50 C to 300 C. These plants remained at their original temperatures 24 hours each day for two weeks. All other conditions were the same for all seedlings. The growth rates are shown in Table 1. Table 1. Growth rates for pine seedlings in Batch I Experiment II A

is too hot for the cell to handle‚ it breaks up or ’melts’‚ releasing what was inside of the cell. This is shown by the results in the graph by the lower temperature not showing much pigment diffused into the water and there being a lot of pigment in the water diffused at a higher temperature. Temperature can also affect the rate of diffusion because a higher temperature will cause molecules to move faster and increase the rate of diffusion‚ allowing more pigment to pass through the membrane‚ in the

The effects of environmental temperature on respiration rates of mice were observed in this experiment. I hypothesized that when environmental temperature decreased‚ the respiration rate of mice would increase. I predicted that if environmental temperature decreased‚ the respiration rate of mice would increase. The respiration rate of the endotherm was measured using the Qubit/Vernier system and the S152 CO2 gas sensor‚ a device that measured the CO2 concentration in the air. The independent variable

How do limiting factors affect the rate of photosynthesis? Rate is the measurement of an amount of product or time. In the case of the rate of photosynthesis‚ it is measuring the gain of mass or growth over time. If the plant is an aquatic one that grows in water the rate of photosynthesis can be measured by counting oxygen bubbles or the volume of gas produced in a measured time period. A limiting factor is something that is present in the environment that has a short supply and because of that

that if a small amount of salt was added to the reaction‚ then it cause the rate of the reaction to speed up‚ but if too much salt was added‚ then it will instead decrease the rate of the reaction. The data revealed that no additional amount of salt was the reaction that had the highest rate. As shown previously in the data table‚ the first trial’s average reaction rate of 4.5 mL/min was higher than the other two reaction rates where salt was added for trial 2 and trial3‚ 2.125 mL/min and 3.5 mL/min

Siblings can have a tremendous impact on a child whether they are younger and older. The theory that best fits me is the youngest brother of brothers. In this theory‚ it says "impulsive‚ and willful‚ daring and imaginative‚ annoying and irritating‚ needs superiors and loves authority." I think the theory is false because most of those traits do not fit. A well fitting trait is being calm. I do not make a lot of noise‚ nor do I bother many people. This goes against annoying and irritating. I want

Biology Coursework ¡V Does The Light Intensity Affect the Rate of Photosynthesis The Investigation In this experiment I will investigate the affect in which the light intensity will have on a plants photosynthesis process. This will be done by measuring the bubbles of oxygen and having a bulb for the light intensity variable. Variables The input variable which will be used in this investigation will be the light intensity (this will be a 100Watt bulb being moved closer and further away from
