INVESTIGATING FACTORS AFECTING THE RATE OF PHOTOSYNTHESIS! Testing Carbon Dioxide Done by: Krish S. AIM: is to plan and carry out an investigation on factors affecting the rate of photosynthesis. We are doing this by investigating the amount of bubbles produced by waterweed to show the rate of photosynthesis and the effects of carbon dioxide (CO2). HYPOTHESIS: I think that the rate of photosynthesis will increase as the rate of CO2 increases this can be seen by the bubbles produced from

Chemistry Lab Report (Design) Factors affecting Rates of a Reaction (Kinetics) KINETICS DESIGN LAB Research Question: Does the concentration of Potassium Iodide (KI) affect the rate of its reaction with hydrogen peroxide (H2O2) (of a fixed concentration)? Introduction: There are several factors that affect the rate of a reaction. Some of them being Pressure (if the reactants are Gases)‚ Temperature‚ Presence of a Catalyst‚ Surface Area of the reactant‚ and Concentration. According to

Light and nutrients. Light is the key abiotic factor which controls the growth of woodland. It controls the spacing of the trees‚ shape of the trees and the shape and structure of the shrub and ground layers. If a trees branch does not receive enough light it will die. Irelands native woodlands are deciduous so there is a dramatic variation of the amount of light which reaches the forest floor through the seasons. In spring when the leaves have yet to grow and the temperature has begun to rise the

Title: Factors affecting reaction ratesProcedure A: Effect of ConcentrationAim: To investigate how the concentration of a reactant affects the rate of reaction. Hypothesis: The more concentrated the reactant‚ the faster the rate of reaction. Materials: 2M hydrochloric acid solution‚ magnesium wire‚ distilled water‚ 4 test-tubes‚ measuringcylinder. Procedure:1)10mL 2M hydrochloric acid solution is poured into a test-tube using a measuring cylinder. 2)A 3cm length of magnesium wire is added to

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

Who Commits Crime? Statistics indicate that men are more likely to commit crime than women. For example‚ in 2002 80% of known offenders (481‚000+) were men. As there are a number of problems with the reliability and validity of statistics‚ an alternative to information are self-report studies. These are anonymous and some believe because they all but guarantee anonymity they encourage respondents to be more truthful than if they were involved in an interview. In the past‚ sociologists tended to

Raszewski “The greatest war in history can be produced without the intervention of any great criminals who might be out to do deliberate harm in the world. It could be produced between two powers‚ both of which were desperately anxious to avoid a conflict of any sort.” (Butterfield‚ 1951: 19–20) The security dilemma is one of the most important theoretical ideas in international

Factors affecting the rate of reaction between a metal and an acid The rate of a reaction can be measured by the rate at which a reactant is used up‚ or the rate at which a product is formed. The temperature‚ concentration‚ pressure of reacting gases‚ surface area of reacting solids‚ and the use of catalysts‚ are all factors which affect the rate of a reaction. Individual properties of substances also affect reaction rates. The scope of these properties is broad and there are few generalizations
