The children had shown some interest in the lotion I was putting on my hands. I have a lemon lotion and a strawberry lotion. They smelled both of them on their hands and compared the smells, talking about which one they liked the most. The following week we were making lemonade. We began the day with having a lemon on the table and, after the first group of children had arrived, we cut it open. They compared the smell of the lemon to the hand lotion. "It smells like the lemon," they decided.
