Build the tallest free-standing tower. (you may not tape your tower to the table in any way. your tower must stand on its own long enough to me measured.) materials: 1 piece of paper, 30 cm of tape, and scissors grade: the group that builds the tallest free standing earns an extra bonus point on their first test scientific method: 1. make observations about the materials and the given task. 2. state the question or the problem to be solved. how tall can a free standing tower be built using only 1 piece of 8.5"x11" paper and 6" of tape? form an hypothesis: the paper can be built to 3. cm tall using the materials and the rules provided.
