MAterials : Leaf (From the Singapore sunflower) , datalogger, CO2 gas sensor connected to the datalogger, a glass bottle and last but not least, a light (lamp from IKEA)
First off we placed the leaf inside the bottle with the help of blue tac. Then Shalini (one of our group member) blew gently into the bottle. She produced CO2. Then we set the datalogger to 30 minutes. Then we placed the CO2 gas sensor on the tip of the bottle. Then we on the light.

Then HORRAY!! We've got our results! We noticed that the graph (from the datalogger) first got higher (increase in carbon dioxide) then lower.(decrease in carbon dioxide) We can also see some water droplets in the bottle.
Carbon dioxide is needed during photosynthesis.
Conclusion: The amount of carbon dioxide decreased as the leaf is taking it in to make food.

Wow...You are totally right! Carbon dioxide is needed durng photosynthesis and that explained why the amount of carbon dioxide is getting lesser.
ReplyDeleteI like your conclusion. Keep up the good work!
