As second graders learn more about forces in science (balanced vs. unbalanced), we're putting that into action in engineering. Using Legos, second graders had to work in teams to build a bridge but that met certain criteria. A boat had to pass under the bridge and it had to hold the weight of a brick.
Not all groups were successful, but their designs are giving them a better understanding of what balanced and unbalanced forces mean! Way to go second grade!
