I love “Hands On” Museums. Before Seder (even several days before Seder), invite your kids to a Seder Plate Discovery Zone. Encourage them to feel and hold every item that goes on a Seder Plate. How many kids have ever really touched maror? shankbones? Hand out rubber gloves so that they can easily handle maror; let them put on aprons and make charoset using a simple recipe. Show how you broil an egg. You can even have them make their own Seder plates. Ask them to become docents at the Seder and lead a tour around the Seder Plate.
