Object lesson: How do we feel when we make a wrong choice?

I had a group of boys and a group of girls come up front. The boys ate a slice of lemon and the girls ate a slice of apple.

I compared the way they reacted and felt to the way we feel when we make wrong or right choices. The boys felt sour and had a bad taste that lingered in their mouths. The girls enjoyed their apples and wished for more. It was kind of silly but the kids really liked it. I used it for both jr. and sr. Primary.
