Inspired by the recent news of the rerouting of the Dakota Access Pipeline, third grade students designed, built, and tested their own pipelines.
Using straws, tape, wood sticks, and cups, they were challenged to create a pipeline with as few leaks as possible. When three straws were attached to the starting point, they were asked to build around sacred ground to get to their end point.
Water was poured from one end and had to travel to the other end. Each group presented their pipeline by identifying what they thought would work well and where the potential weaknesses were located.
There were many different styles of connecting the pipes and ways of using gravity to make the water flow.
