My theme found out that there is 14% part type O in the air. The correct per centum of oxygen in the air is 21%. At first, when we put the test provide everyplace the examine, the flame flickered.

Also, we should have checked that every group had the same amount of clay, if some groups had less clay, then their penny would have floated more swiftly. Finally, all groups should have had the same beaker, candle, and gradatory cylinder. If my group had used a larger test tube then there would be more water because there would be more oxygen.
