| Explore | We know the process of photosynthesis and cellular respiration and we has done several lab procedures reguarding both. |
|---|---|
| Research Question | How does CO2 effect the Ph levels of the elodea plant. |
| Predictions | Due to the lack of CO2, the Ph level of the tube without CO2 in it will not change as greatly as the tube that is rich in CO2. |
| Experimental Design | Take 4 test tubes, place ten ml of phenol red inn each beaker and add a few drops of diluted soap solution to each tube. Blow into two of the tubes for 60-90 seconds then place one strand of elodea in each tube. Set up 25-watt heat lamp and set all 4 tubes in a test tube display and place the display under the heat lamp. |
