Blow Students' Minds With Crystals That Grow To 300 Times Their Weight!
These growing crystals absorb 300 times their weight in water. You can also color them for amazing results. Use them to introduce students to the environmental benefits of hydrogels, superabsorbent polymers used in items like diapers. They are nontoxic, so your students can get their hands right in them. When the experiments are done, let the water crystals dry out and use them again for future science fun.
In the U.S alone, nearly 30% of educational standards are overhauled, revised or edited each year. Tracking these changes demands the full-time expertise and we have the tool to manage those standards, so you can trust us as the leader in standards alignment. Correlations are made for all State, National, and Common Core Standards. In addition, we have Head Start standards for early childhood. And most recently, we’ve added both National STEM Standards and Next Generation Science Standards (NGSS).
