Title: Photosynthesis experiment

Date started: 15 may 2009

Equipment: funnel x2 test tube x2 oxygen weed x2 large container x2 a few rocks and LOTS of water. we have done 2 experimants one is in our science lab in the dark and another on our dining room table in the light

Proposition: I think that little bubbles will appear and the test tube will possibly rise up

Observation after one week: You can now see some bubbles appearing in the funnel and test tube both in the light and dark. I think that the heat might have deleted some of the bubbles in the light one

Observation after 2 weeks: the experiment in light has produced a lot of oxygen I think its because last week we put to much water in it because it didn’t start properly then when our cats and kitten (nisha sidka ebony and Judas) started drinking the water so its water level has gone down now its producing more oxygen then before. The dark one has just been haply making oxygen it has made more oxygen then the light one.
