We’re in the midst of learning about states of matter in Kindergarten. I can’t think of a more interesting matter experiment than this one – an old recipe from a Teaching Elementary Science class – concocting “Oobleck.”
Oobleck is hard to classify – it’s a liquid, but much like a solid. It gets drippy in your hands and then reverts back to a solid state. I have always loved hearing students make observations about it.
Beyond the cool problem solving factor, it’s just fun to play with. It would be a great April Fool’s Day experiment or a good gross one for boys of any age. Plus, it’s great for fine motor development. Because Selah loves to immerse her hands in paint, mud, dough, whatever – this stuff was an absolute hit! Let me know if you try it!
