Adaptations: Bird Beaks - Version 3

This is the most advanced of the bird beak labs, as students need to record times, calculate average and graph data.  For simpler bird beak labs, check here and here.

There are 8 stations.  At each station, the student will use each provided beak to collect a prescribed amount of the food source.  Another student will time how long it takes for each beak to accomplish the task.  Several trials will be performed with each beak.  Then the averages will be calculated and a bar graph will be constructed.
