Educators Love Crystal Clay®

"Crystal Clay® is an excellent addition to the classroom... students were able to see how the entire root system begins...students eagerly made their way to the science station to make discoveries.." Mrs. Coppley, Third Grade Teacher

Excellent visual reinforcement
of the life sciences curriculum

Lets students see the whole process of plant growth
from germination to maturity. Fast growing for immediate results -
germinates in 1-2 days.

See root growth behavior not observable in regular soil
or standard hydroponics.

All ages will find it easy to set up,
and have fun watching the crystals swell 100 times in size.

Affordable for the whole class or for home schooling


To keep prices down, and to make the kits more appropriate for the classroom, our educator kits come without holograms, fun creatures and sparkles, but with everything else needed for a successful growing and learning experience.

Crystal Clay® has been approved by the California Department of Education, and can be purchased using Instructional Materials Fund (IMF) Resources in that state.
