Editing My Experimental Design

Today I'm going to start my experiment right after I finnish editing my experimental design. I also learned how to use and oxygen probe, and I read all the criteria for data studio. Tonight I am going to finnish editing my experimental design. I already fixed my hypothesis, it didn't have my independent and dependent variables all I included was my variables. My hypothesis was also too much like a prediction, it included too much of what I thought was going to happen. I changed it from, "If you water the primrose with acid rain, it will slow down the oxygen production of the primrose." No my hypothesis is, "If the primrose plants are watered with different pH levels of acid, then it will change the oxygen production of the primrose plant." I also Made a new data table and tried to make my procedure more specific.
