Our Experiment Results :

From our experiment , we can conclude that White light is best for the plant to produce more oxygen. 

This can be backed up with our experiment findings from our 3 experiments. 


The results for which light will allow the plant to produce more oxygen is as follows. 


Experiment 1  (Test experiment) : White Light 
Experiment 2 :                                White Light 
Experiment 3:                                  Green Light

We concluded that White Light is the best lights as it allowed the plant to produce the most oxygen 2 out of 3 times or around 66%. 

The Green Light result may be because of the fact that the particular stalk of plant may be more subjective to green light and thus produced more oxygen. This can be classified as an exceptional case 


To conclude , we can say white light overall allowed the plants to produce more oxygen.

Steps for recording data : 

1) Move to eye level to look at the water level.
2) Take a marker, and mark the water level at eye level. 
3) Take a ruler, and measure with the 0cm marking aligned and placed at the marking. 
4) Record the marking, if there are 2 markings, measure difference between them and record it into the table.
