1. Science practice and materials. Students will do and activity “Oobleck –what scientists do?” Oobleck is a green, oozy substance (from “outer space,” in this fictional account) that both begs and eludes description as it initiates students in the nature of inquiry and definition and sparks vigorous debate about its properties.
2. Creating river models using a dripper system and diatomaceous earth, students acquire geological terminology and begin to understand rivers as dynamic, ever-changing systems. They investigate the concepts of erosion, pollution, toxic waste, and human manipulation of rivers, and gain understanding of controlled experimentation.
