This kit has been designed to introduce young students (K-4) to the concepts of matter in a fun, safe, hands-on way. Students are given samples of both a solid and a liquid so that they can perform some simple experiments that demonstrate the differences. The students are then given a sample of “Our Friend Oobleck” (a non-Newtonian fluid) to use in the same experiments and are asked to determine if Oobleck is a solid or a liquid. This kit contains everything needed for 30 students to perform the experiments while working in groups of 3.
