A STEM project in Sally Mankoo’s classroom turned her second graders into geotechnical engineers studying soil types and erosion factors. 

Working collaboratively, three groups of students built three different land models on 2-liter bottles: soil only; sticks and rocks; and planted soil. Following the scientific method they tested how water moved across each model and recorded their observations. In the next step, with their engineer caps on, they used toothpicks, cotton balls, aluminum and play-doh to design drainage devices or filtration systems that would hold the land in place, and control erosion.

STEM-based (science, technology, engineering, math) learning allows students to tinker with tech and non-tech tools, explore and share ideas and solve problems in collaborative environments.
