Can someone please give me a testable question for Oxygen. I cant think of one for the life of me.


  1. Answer:


    You could test effect of oxygen levels on growth of a regular houseplant. You could make the control to be plant grown under regular atmospheric Oxygen level. And for changing variables you could have one plant grow at low oxygen level compared to atmospheric oxygen and another plant to grow at higher levels of oxygen when compared to atmospheric oxygen.
