Primarily aimed for teachers of students in grades kindergarten through second, “STEM For Young Learners: Marshmallows” presents jam-packed projects for budding scientists, mathematicians and engineers. Using the theme of marshmallows as a springboard, Young scientists will explore the concepts of density and displacement as they cause marshmallows to sink and float. Students use desktop publishing software and the Internet create to a marshmallow mosaic. Young engineers are challenged to build a bridge across a span of books that can hold a cup filled with the most pennies. Young mathematicians will use rulers to measure twelve spaces in which to write the letters in the word marshmallows. They will decorate the letters with mini marshmallows and display the finished marshmallow masterpieces on a classroom bulletin board.
