As part of second grade’s Properties of Matter unit in science, students explored how materials can change form under different conditions. This week, second-grade scientists created Oobleck (a non-Newtonian fluid) named after the classic Dr. Seuss book, Bartholomew and the Oobleck. Oobleck–made from cornstarch and water–offers a perfect demonstration. It behaves like a solid when pressure is applied but flows like a liquid when left alone. The students were amazed as they experimented with squeezing, poking, and letting the Oobleck drip through their fingers. They shared observations about the unique properties and debated whether it was a solid, liquid, or something in between!
