I have water beads (and spikes, cubes, and crystals) leftover from science camp. Check out the toy aisle at Walmart for water beads. If you have a plant nursery, see if they sell water absorbing crystals or Soil Moist crystals. You can put the beads in your garden or in your plants’ soil. I send home extra beads for the teens’ younger brothers and sisters.
I’m building better Chemistry lessons this year—more challenges and more analyses. I have come across loads of ideas! Let me share: Water Beads (Elementary level), Growing Spheres for 3D Modeling, (Secondary Level) Grow Spheres Help Students Absorb Scientific Principles (Secondary Level), HST Water Beads Lesson #1 and #2 (Elementary or Secondary Level), and Ghost Crystals (Elementary or Secondary Levels). I think I’ll make the water beads into a challenge using the HST lesson and these ideas for extensions from Educational Innovations.
