Attached is my lesson plan for the "Sampling for Abundance" activity. I experimented a bit with my methodology for this activity and had students pull relevant information about sampling techniques from a non-fiction text (select portions of the teacher's edition of the lesson write-up) prior to them conducting their sampling. It seemed to work well, with students enjoying the opportunity to work in a group to "research" the activity prior to doing it. I believe the key in setting up a successful version of this technique is providing students with very pointed questions for them to answer with the aid of the text.
