Is it a solid? Is it a liquid? It's both! The second grade students have been investigating the different states of matter throughout their current unit. During the last week in February students investigated a very special substance called oobleck. Oobleck is both a liquid and solid. When pressure is applied, oobleck reacts like a solid; however, without pressure it is a liquid. See the fun the second grade scientists had below!
