What did you do for your experimental procedure?

First I put a magnet at hte bottom of one pot. Then I filled the pots with soil, I then planted 3 radish seeds per pot. Next I put one magnet ontop of another pot other than the one I already put the magnet on the bottom. Every 2 days I would water measure growth and record in my notebook for 14 days.

Did you have a pot with no magnets? Otherwise, how do you know there is a difference?
