In our area, it’s snowing again. After lessons and play outside, plan some fun. Let’s make crystals! My two favorite experiments are Salt Crystal Garden (with liquid bluing), Alum Crystals, and Alum Geodes. Scroll this issue of Celebrating Chemistry: Chemistry Rocks for two experiments: Epsom Salt Needle Crystals and Borax Snowflakes. Another idea is to make Ghost Crystals with Ghost Crystals, which are water gel crystals or beads, the type which absorb and expand. I like cubes and spikes, too. Allow time for the crystals to grow. Check results once a day.
