On the last Late Start, 5th Grade combined classes and then divided into small groups. Each group was given the challenge of building the tallest free-standing tower with a limited supply of spaghetti, tape, string, and a marshmallow. Students found that cooperation helped them succeed! Some groups were successful and ended with a free-standing tower. Others were not as successful, but they had great ideas of how they'd build it if they had another chance. STEM stands for Science, Technology, Engineering, and Math.
