Lab:  O2 in Atmosphere

 

Question:  Does burning oxygen (O2) get rid of it?

 

Hypothesis: (Predict % of O2 in the air with reason

 

Procedures:

1.      Measure the total volume of water that a 100ml cylinder can hold (to the very top).

 

2.      Wax the candle to the bottom of the glass bowl (so it won’t float).

 

3.       Fill the bowl between 1/4 to 1/3 with water.

 

4.       Place the 100-ml cylinder (no water) over the burning candle and record the amount of water that the cylinder drew up.

 

5.      Calculate the % of O2 in the atmosphere (ml H2O / volume of cylinder)
