None of our ice experiments are terribly original. There are a lot of them floating in blogosphere with winter themes, but I am glad that we got to reuse some of those wonderful ideas from The Adventures of Bear and Almost Unschoolers. Anna had a kick first freezing some of small plastic toys that she had and then devising strategies to free them. Her first idea was to break the ice with a spoon. As she quickly found out, this didn’t quite work. Then we added some food coloring to watch how colors penetrate into ice, and I explained her about salt making ice melt faster. We could observe how the hole in the ice was formed in the place where we added salt. Finally we poured some warm water in the ice to make it melt faster. We also observed that ice floats in water – something that she could link to the movie about polar bears that we watched together.
She immediately wanted to repeat the experiment, but instead we froze colored water to make an experiment on color mixing later this week.
Edited to add: My husband was not pleased at all about salt and ice experiment. I didn't know it before, but apparently you can get a frostbite if ice, salt and water get on your skin if you let the mixture stay for a couple of minutes.
