• water.

Oil and Water Object Lesson

Ask:

• Do you think liquids always mix?

Say: Let’s find out.

Fill the jar halfway with water. Put in two drops of food coloring. Ask kids to guess what’ll happen when oil is added. Add oil and screw on the lid tightly. Shake the jar, turn it upsidedown, and observe how the oil and water react.

Scientific Facts:

• Oil and water won’t mix because their molecules have different charges or polarity.
• The two stay separate with a very clear boundary because they’re “polar opposites.”
• They’ll never mix. That’s why it’s impossible to put out a grease fire with water.

Talk Teasers

Ask:

• Was your guess correct?
• What did you observe about the oil and the water when you tried to mix them?
• Do you think there’s ever a situation when water and oil will mix? Explain.

Read the Scripture.

Ask:

• How is this experiment like or unlike what happens when we hang out with people who don’t believe in Jesus?
• Do you think it’s okay to hang out with people who have different beliefs than you? Why or why not?
• What do you think God would tell us about being friends with people who have different beliefs?
