Students explore the differences between living and nonliving things through the lens of the nursery rhyme, "Hey Diddle Diddle." After bringing the characters to life, the students discuss the concepts of living and nonliving and act out frogs and rocks. This is followed by distinguishing what items in the classroom are living and nonliving and charting them in either category. Students then act out various pictures, and classmates guess whether the picture shows something living or nonliving.
