rior Knowledge Questions ​(Do these BEFORE using the Gizmo​.) ● To survive, what gas do we need to breathe in? ___​Oxygen​________________________________ ● Where is this gas produced? ... ____​Carbon Dioxide​_____ Gizmo Warm-up During ​photosynthesis​, plants use the energy of light to produce ​glucose​ (C​6​H​12​O​6​) from ​carbon dioxide​ (CO​2​), and water (H​2​O). Glucose is a simple sugar that plants use for energy and as a building block for larger molecules. A by-product of photosynthesis is oxygen. Plants use some of the oxygen they produce, but most of it is released. In the Photosynthesis Lab ​Gizmo™, you can monitor the rate of photosynthesis by measuring oxygen production. 1. Observe the left pane closely. What do you think the bubbles are? __​CO2 molecules​__________________ 2. Select the BAR CHART tab. On the graph, notice the ​Oxygen production ​bar. Move the Light intensity ​slider back and forth. How does light intensity affect oxygen production? ______​If the light intensity is high and the CO2 level is high then more oxygen is created.​___________________________________________________________________ 3. Experiment with the vertical ​Temperature​ slider (upper left) and the ​CO​2​ level​ slider. A. How does temperature affect oxygen production? _​If the temperature is too high or too low, no oxygen will be produced.​__ [Show More]
