Harry Hurst Middle School 6th grade teacher Brandy Dufrene had her class complete a collaboration challenge in order to instill the importance of group work in science. Groups had to use string and a rubber band to make a tower out of cups. The students were not allowed to use their hands or any other materials to complete the collaboration challenge.
