Seder plate

Hand painted Seder plate

To teach children the symbols on the Seder plate or to use as Pesach decoration paint a common white plate with the Seder symbols. 
Accordingly, the seder is one of the most sensory-heavy  rituals of the Jewish year. During the seder, we don't just tell the story of the Exodus, we see, smell, feel, and taste liberation.
Many of the elements of this sensory experience appear on the seder plate (k'arah), which serves as the centerpiece of the seder table. The seder plate traditionally holds five or six items, each of which symbolizes a part (or multiple parts) of the Passover story.
