Mrs. Marcus’ fourth grade class joined Mrs. Fedas’ AP biology class for a lab about natural selection. The fourth graders were divided into groups of four and each member was given a different method for gathering food (fork, spoon, knife, or his/her fingers). They had to gather food (beans and pasta) using that method in a given amount of time. We graphed the results from four generations. Which animal will best survive? I love working at a PK through 12 school!
