– Six different essential oils (we used Lemon, Eucalyptus, Lavender, Spearmint, Basil and Rosemary)
– 12 cotton balls, fabric squares or small handmade yarn balls
– smell boxes or shakers (no need to have the actual Montessori ones, any jar with a lid will do, just color-coat the lids with paint, permanent markers or whatever is on hand). Two sets of six are needed.
– computer, tablet, smartphone (anything with internet connection) or a book with information and pictures on these essential oils
