1. Probably they include negatives and, if possible, corroboratory controls. Is your negative control a adjudicate plant that is place in a mount with no legume planted in the pot?

Or, if you dont think that will work, will you plant the legumes and let them grow and transcend before you plant yo ur test plant?7. How will you record what you have done? Will you collapse a spreadsheet and record that, for example, you have gave all the plants a cup of water per day or a quart of water twice a week? Where will you note the growth of the plant? how some(prenominal) weeds you pulled? Will you note the conditions of the leaves of your test plant or the conditions of the legume plants? Where will you note any unforeseen changes? 8. How will you write up your results? Most scientific papers have 5 sections.
