This is a fun activity that can be used in conjunction with a study of Passover.
Locate the Leaven – As the Passover feast was celebrated down through the years by the Jews, the evening before the Passover feast began, the head of the family would lead his family through the house by candlelight, searching for leaven. No leaven of any kind was allowed to be in the house during the length of the Passover feast which was 7 days. Sometimes Jewish families would sell their leaven to their Gentile neighbors for the length of Passover, then buy it back when Passover was over. Leaven is any kind of agent, like yeast or baking powder, that causes bread to rise. Hide a package of yeast in the house or write the word “leaven” on a small index card and hide it. Use a battery operated candle or flashlight to let everyone else search the house to locate the leaven. Take turns hiding it, or hide several and see who can find the most.
