The Pony Artist's Ice Melting Experiment

"Mommy, pouring water on ice melts it."

What do you think? True or false?

The Pony Artist had spent some time working with snow on winter days here in the Southern US. The temperature was always well above thirty-two Farenheit (0 C). We decided this was a good opportunity for a science experiment . The Pony Artist did a great job of designing a procedure to test her hypothesis.

She knew immediately that our set up included an ice cube,with water added. I reminded her that we also needed an ice cube alone in a second container to be sure that the water was what made the ice melt.

I suggested that we actually make two of each set up and conduct it twice, once on the counter and once on the refrigerator. Looking back, I short circuited the  learning process slightly. It would have been better to do the experiment her way, let her see that the ice melted both ways, then perform the next experiment.

We measured the mass of each container in case we had confusion about where ice had gone later.

In the end, that was not necessary, but it was good counting and measuring practice.  

The Pony Artist checked her a set up periodically.  Eventually, she ended up with this.

She concluded that ice melts when it is warm and (liquid) water freezes when it is cold. 

Not bad for a pre-schooler! My husband's co-worker observed an adult trying to melt ice on his wind shield by throwing water on it.

What question should the Pony Artist answer next?
