History/Civil War
In 1837 Mr. Proctor and Mr. Gamble began making and selling soap and candles. During the Civil War government contracts to provide the Union Army with soap and candles kept the factory busy. In 1879 Mr. Gamble’s son developed Ivory Soap. Proctor and Gamble has a great PDF that outlines the history of their company.
•Fill up the bathtub with some warm water. Allow your Civil War soldiers to hand wash their shirts with Ivory Soap. Did they notice that the soap floats? If you have some other kinds of soap, see if they can float.

Science/Chemistry (Ivory Soap Experiment) 
Soap is a form of matter because it takes up space. Describe its physical properties: size, shape, smell and color.

Steven Spangler shares information about Ivory Soap on his web site.

•Explain how when Ivory Soap was first made it didn’t float. About 3 years into the manufacturing the gentleman who was running the machine forgot to turn it off and went to lunch. This whipped a lot of air into the soap. He didn’t say anything to his employer but packaged the soap and sent it the stores. Later mail started coming in asking for more soap that floated.

Bible
Do you think the gentleman should have told his boss about his mistake?
What does the bible say about God turning bad things into good? Or confessing your mistakes?
•Read Proverbs 21, verse 2 states: Every way of a man is right in his own eyes, but the Lord weighs the heart.
