Breating rate, TV, ERV, and IRV. Being able to take an accurate pulse and respiratory rate is a core skill for first aiders. 11 Collect mean rate of oxygen uptake results from other groups in the class. Get Your Custom Essay on Investigating the effect of temperature on the rate of photosynthesis Just from $13,9/Page Get custom paper During my actual experiment I used 7 different temperatures ranging from 0oC- 65oC. He wants to measure how oxygen levels affect the rate of photosynthesis in plants. Set up a boiling tube containing 45 cm³ of sodium hydrogen carbonate solution. test the effect of temperature on the rate of cell respiration in nongerminated vs. An assumption being made in this experiment is that the gas bubbles being counted are only oxygen, and that production of oxygen is proportional to the rate of photosynthesis. When the temperature rises, the particles in the reaction move quicker and collide more, so the rate of photosynthesis rises also. A variable that is hard to control is the effect of temperature as the lights used may heat the water. Restrictions I found in these experiments could … This experiment was broken up into two parts. Correct answers: 3 question: Justin is planning his science fair project. Method. Is this an example of a scientific investigation or an experiment? Practical - investigation of factors affecting photosynthesis Investigate the effect of light intensity on the rate of photosynthesis using an aquatic organism such as pond weed. An experiment because it tests a cause and effect relationship An experiment because it does not ask a testable question An investigation because it uses only observations An investigation … The first part tested the light-dependent and light-independent reactions of spinach leaves by using the Pasco CO2 sensor and a Testing Chamber. Photosynthesis can be described as a process by which water, carbon dioxide, and light energy are converted into oxygen and glucose. Another assumption is that all the bubbles are the same size. At the optimum temperature, the enzyme is most efficient and the rate if maximum. The second part of the experiment tested the effects of different frequencies of … The experiment includes 2 experimental set-ups and 1 control set up. At temperatures above 40°C the rate slows down. To investigate the effect of light intensity on the rate of photosynthesis.
