Kids love this one!  You’ll love it too because it is easy and you can adapt it to any lesson.

In this application activity children determine right and wrong choices in various situations and participate in the activity using their sense of taste.

The only supplies you need are lollipops (or any candy) and lemon slices.  When you talk about good choices they lick their lollipop.  When you talk about a bad choice they lick their lemon slice.
