As part of their study of matter, Winthrop Avenue fourth-grade students learned to make sticky, gooey slime and oobleck during a videoconference lesson with Ann Arbor Hands-On Museum.
In addition to reviewing their newly-acquired classroom knowledge of the states of matter, the student-scientists utilized their listening and lab skills in making slime and oobleck recipes with cornstarch, water and food coloring. They were instructed to utilize their senses to determine whether the substances were liquids, gases or solids. After much deliberation, they learned that slime not only constitutes a liquid and solid, but is called a non-Newtonian fluid.
The best part of the lesson, however, was being able to bring their slime and oobleck samples home.
