We love playful science activities for preschoolers and are always exploring classic science experiments, adding our own unique and fun twists! Sensory science is an appealing form of play and learning for my son. We have done many hands-on sensory science activities that spark curiosity and develop a love of learning! Find out what happens to Ivory soap in the microwave.
Ivory Soap In Microwave
Ever wondered what Ivory soap does in the microwave? So easy! The photos tell it all! Read more about the science behind this Ivory soap experiment as well. I would have to say someone (namely a 4-year-old) was pretty excited and interested, and then absolutely amazed by the results! (Excuse the dirty microwave!) This is a great experiment for showing reversible change!
Want another great example of reversible change? Check out our water experiment!
What does Ivory Soap Do In The Microwave?
When you heat Ivory soap in the microwave, the appearance of the soap is changed but no chemical reaction occurs. This is an example of a reversible change or physical change.
The soap expands in size because the air and water inside the Ivory soap heats up. The expanding gas (air) pushes on the softened soap, causing it to expand up to 6 times in size. Microwave popcorn works in much the same way!
Ivory Soap Experiment
You will need:
- bar of Ivory Soap
- large microwaveable bowl
- Optional; tray and play accessories
How To Microwave Ivory Soap
STEP 1. Unwrap and place your soap in the microwave.
STEP 2. Microwave for 1 to 2 minutes.
What’s even better is the texture which isn’t messy! I wasn’t sure what it was going to feel like and many messy textures turn off my son’s interest.
This is flaky and stiff so we could break off chunks. I supplied him with spoons and cups and then thought a plastic knife would be a great idea! So did he! He spent a great deal of time sawing little pieces until there were just flakes left!
This was a super spontaneous science experiment for easy morning fun. I had no idea how it would go or what would happen or if he would even be interested, but he was!
