Teacher
procedure:
Mix all ingredients in bowl or empty used
container that can be stained. I use an old laundry measuring cup to stir and pour.
Cover tissue paper in each cup with 2 or 3 tablespoons of the mixture. Sprinkle a little extra
salt over the top of each finished cup. When all cups are done, pour any remaining liquid to even things up.
The crystals will begin growing right away. Begin in the morning so
the children can observe the changes during the rest of the day. The next morning they will be excited to see the final product.
Note: I do not send the cups home with the children as the crystals
fall off the paper, and do not hold together. If children accidentally touch the crystals, they should wash their
hands to avoid rubbing the solution in their eyes.
