Today is our second day of experimenting with Elodea. We are also using a light source. We are testing how light affects photosynthesis. Instead of using a Co2 tablet, we are using baking soda for CO2. There is tape on the table, and we put the light source at the end of the tape. The tape is already measured.Then you put the elodea that is in the test tube, on 10 cm for 4 minutes. After 4 minutes my table's Elodea had no bubbles coming up from the cut part of the Elodea. Our problem was that that the baking soda did not dissolved yet. It was it still at the bottom of the test tube. After the second time we tried the experiment on 10cm we got 3 bublbles. Then we started on 20 cm and we got 2 bubbles.

ReplyDeleteJust to clarify, the light source was a lightbulb. Also at 30 cm there were no bubbles.
Maddie-
ReplyDeleteThere was too some bubbles. I think
No Maddie, there were not bubbles at 30, no ones results showed that.

The light source was a lightbulb and at thirty centimeters there were no bubbles and i think everybody's results showed that. we only had bubbles at the first two tests we did not at 30 centimeters
