KENTUCKY (04/21/17) — Some of you might use it in the shower, but have you ever considered putting it in the microwave?

INGREDIENTS

  • Ivory Soap
  • Microwave
  • Paper Plate


INSTRUCTIONS
STEP 1:  Place the bar of Ivory Soap on a paper plate. Describe and classify the soap by its observable properties.
STEP 2: 
Using the microwave, heat the soap for one minute.
STEP 3: 
Remove the Ivory Soap from the microwave and observe. Describe and classify the soap by its observable properties. Develop a model to describe how the soap is made of particles too small to be seen. 

EXPLANATION
The water and air trapped inside the bar of Ivory Soap are heated by the microwave. This causes the water to evaporate and the air to expand.  The expanding air, forces the Ivory Soap to puff up.
