These tubs are diffidently complete. Each and everyone of the activities are fun, quick and in-depth. I really like that the experiment cards, vocabulary cards, and other printed material. It really makes these activities more organized and exciting.

These tubs are great! Very easy to follow instructions! High quality material and best of all FUN

Saves so much time when most of the materials needed are in the tub! The materials are easier to use than our science curriculum materials. Easy to set up and understand the concepts presented. Students love it.
