Drop the bar into the water and observe what happens. You will notice that the soap floats. If you have other bars of soap that aren't Ivory brand, drop them in the water and see what happens. They will sink to the bottom of the container. These tiny air pockets are what allows the soap to expand the way it does when it is heated. Remove the soap from the water and let it dry before microwaving it.
Method 2. Talk about a hypothesis. A hypothesis is an educated guess about the outcome of an experiment. Discuss the air pockets in the soap and ask your child what they think will happen to the soap when it gets heated.
Write down the hypothesis before you begin. Can they think of anything else that expands when heated? For instance, both marshmallows and popcorn expand when you heat them up. Experiment with different types of soap. Ivory soap is special because it has air whipped into it, but other soaps do not.
Perform this same experiment with different types of soap and observe the various results with each brand. Record your results and observations underneath your written hypothesis. Discuss the results. Talk about what happened with the soap. Ask your child why the soap expanded and why the air pockets are important. Explain to them that there is water trapped in the air pockets and that gas expands when it is heated.
This causes them to bounce off of each other and hit the pockets of soap with such force that they expand out. Discuss the differences between the various brands of soap and the reason you see differences in the results. Yes No. Not Helpful 1 Helpful 6. The entire bar of soaps expands into a fluffy cloud increasing in both length, width, and height. After all its the soap that floats. Your kitchen will smell so fresh and clean when youre finished.
Soap in microwave Let the soap cool for a few minutes and then take it out of the microwave. Even after being microwaved the soap is still good to use. That means that when you put them in a microwave they resonate and the energy builds up until the juice boils and creates an ionized gas and then arcs across the two halves.
The soap itself softens and melts and the air trapped inside the soap expand. Be sure to heat each bar of soap up on the same kind of plate and make sure you heat each bar for the same amount of time. Just as importantly they also heat up any pockets of gas that are trapped inside of whatever were trying to warm.

We left our soap. The variable in this experiment is the soap everything else has to be the same. Place the soap on the plate or shallow container and put it in the microwave.
We did this activity while he was napping and I was feeling guilty. If Mr. Tickles would have thrown it which I can guarantee would have happened , it would not have felt good in his eyes, nose, or mouth. Doing the activity with just my little preschooler let us add a scientific approach to our soap experiment and allowed her to free play, ask questions, and learn.
I was so impressed with the great questions she was coming up with. One of her questions led us to making soap shapes. Steve Spangler Science provides a great explanation about the science behind the soap phenomenon and is where I found the directions. Basically, the soap expands for the same reason popcorn kernels pop. Ivory soap is whipped so it is full of tiny air pockets that expand when heated up. I planned on making popcorn to go along with this activity, but we had so much playing with the soap we ran out of time.
Now To The Activity : Put the soap on a paper plate in the center of the microwave and turn it on for two minutes. Our microwave is above the stove so I let her stand on a stool so she could watch the action. The both of us watched in amazement as the soap just kept growing and consumed the inside of our microwave.
After one minute I pulled half of it out and placed a large portion of the soap that had moved from the center of the microwave back in place and continued microwaving for the remaining minute. And then I decided to do a super cool week series of summer science on my blog, and they balked. By week three, they were all like, " Do we have to do science again? So Joe and I did a few experiments on our own and then quickly petered out, and that's why there hasn't been anything new for a while now.
No involvement on the part of the people who were meant to enjoy all this sciencey summer fun made for a big zero. I did, however, turn the tv right off. They haven't quit complaining about that, and it's been a couple of weeks.
So anyway, I have snuck in a couple of fun science activities in the weeks since they began boycotting all things interesting. They each went to science camp for a whole week two different weeks, for their respective age groups , and they have done some vinegar and baking soda explosions out on the back porch in the evenings. Other than that, though, it's been a summer of doll houses and American Girl dolls and lots and lots of Usborne books. Back to this particular science experiment.
