Here's a great idea for K-12 science curriculum!

Ever seen clear dirt?  Ever wonder what roots look like when they are actually 
growing in soil?  Well your students do too!  With Crystal Clay gel you can 
watch the entire process from germination to maturity.  This unique seed 
growing kit features a clear growing medium to give a close-up 3-D view of root 
growth.  Just add water and the super-expanding clear soil gel swells to 100 
times its size!  Add the included seeds for an intimate view of plant growth 
and anatomy.
