It’s possible that science was never so musical. First-graders at Roadrunner Elementary this week presented “Vacation on Mars,” a Broadway-style musical complete with choreography, costumes, props and sets – and all of it helped them learn the first-grade state science standards. In two performances for the school during the day and one showing on Tuesday evening for the parents, the children opened by singing “Mars, Mars,” and ran through other space-themed songs.
