Easy, fun and rewarding the Miracle-Gro Kids Root Viewer gives children an “ants-eye” view of how seeds take root, flowers emerge and root vegetables grow. The kit comes with everything you will need, an instruction booklet, soil, seeds and plants. The whole project takes about fifteen minutes, then the fun and required patience come into play. Kids loved checking and measuring the root growth every day, something that is aided by the fact that when planted properly, everything grows right up against the clear plastic. There are three different vegetables included, carrots, onions and radishes, and each one grows quite differently. There is even a game where children have to guess which root will grow the longest, be the fattest, etc.
