Scientists in the Classroom, Part II

Last week, Outreach returned to the Morgan Elementary School in Holyoke, MA. This time, I (blog-author Evan Palmer-Young) got to teach a lesson to 4 classes of 6th and 8th graders. The theme of the lecture was, "Evolution by natural selection". I used an activity where students initially varied in phenotypes (cutlery utensils), and had differential reproductive success based on their ability to gather the available food source (beans).

Here are the slides.

Which phenotype do you think was most fit?
