Topic: Understanding matter and energy, properties of liquids and solids
Students design, build and test a structure that involves interactions between solids (plastic) and liquids (water). Students will discover that a flagpole mounted on a plastic bottle will roll over on its side when placed in water. Faced with this problem, students will create a solution that will allow the flagpole to remain upright in the water. With the materials provided, students should arrive at (or be supported to find) a solution that will, either use sand as ballast in a single bottle, or a pontoon system using two bottles to solve the problem.
