The following describes a lab on natural selection.
The materials needed for this lab included a bowl of toothpicks, a bowl of dried macaroni, a spoon, a forceps, a binder clip, a scissors, a plastic cup and a timing device. The procedure for this lab was performed as follows: the number of toothpicks able to be consumed (picked up) in a 30 second period by the spoon was recorded. This trial was repeated a total of three times, then the spoon’s ability to consume macaroni for a period of 30 seconds was recorded for three trials. This procedure was repeated with each bird beak. Averages were calculated for each beak’s ability to consume each food item.
