In this teacher-approved lesson, students will make and play with oobleck (corn starch and water), then write about their experiments. Young scientists will have a blast seeing their oobleck mixtures seemingly come to life.
Tell your students that today they're going to learn about a liquid, that, at times, acts like a solid due to stress or pressure placed on the mixture. This is called a non-Newtonian substance.
Activate prior knowledge by asking questions along the lines of "Who can tell me the difference between a liquid (like water) and a solid (perhaps like cornstarch)?" or "Does anyone have a prior experience with oobleck?"
Read aloud Bartholomew and the Oobleck by Dr. Seuss.
