Materials: Elodea sprigs Test tube and beaker Razor/scissors Water with Sodium Bicarbonate (baking soda) Light source (lamp) Ruler Procedure: PART A. Using the following virtual simulation created by the University of Reading in partnership with Syngenta, you will observe and measure the rate of photosynthesis of Elodea - a Photosynthesis Lab report. 2018/2019. We did this by using a Gilson Respirometer and samples of Elodea plant placed in H2O and NaHCO 3 solutions—both of which were operated under lighte d and darkened external conditions—to measure the consumption of CO 2 during photosynthesis and the production of CO 2 during respiration. Bromthymol blue is used as an indicator for the presence of CO2 in solution. Partager. Subject. 2. • Your DV for each trial should be measured at a minimum, three mes • Students should use prior knowledge of photosynthesis to support their hypothesis. 2) Measuring the production of O 2. Students will work in small groups to design an experiment with one independent variable and test this variable on spinach leaf disks. This experiment will look at the affect of light intensity on the rate of photosynthesis on Elodea plants. 3/15/2017 0 Comments Elodea is this plant: To measure the rate of its photosynthesis, we cut the stalk, so that bubbles would appear more easily. Elodea Photosynthesis Lab Science Project Education Com.
