Within the area of natural sciences, the students of the Second and Third Cycle of the school have joined an activity of the Forest Project where they have had to act as authentic alchemists of nature. First they have collected the yellow wild marigold flowers, Calendula arvensis, that have begun to bloom lining the forest. They have put them all in their glass jars and then they have poured the organic oil they had brought from home – olive oil, sesame oil, jojoba oil, hazelnut oil, … -. Then they have shaken the jar up and down, mashing the mixture well.
Once at home, students should leave the jar on the windowsill, away from direct sun, and each day turn it around, alternately leaving it with the lid up or with the lid down, so that all the flowers are soaked in oil. After forty days they will be able to strain its contents, throw the flowers and store the oil in a place protected from light.
Calendula oil, Pau told us, has many beneficial properties for the skin, helps heal burns, wounds, is healing, moisturizing, soothing and softening.
