This was part of our "cold" day from school last month. It was as low as -35 below with windchill and so there was a 2-hour delay from school which means no morning preschool for my son. In that case, we needed to plan some learning activities at home. Given that he had just done some melting of ice in preschool with warm and cold water and salt water in preschool, it was fresh on his mind, but being the ever dinosaur fan that he is, he wanted to excavate some dinosaurs from the ice (because that quite possibly be how some of them died.)
Although we took it all a couple steps further than he did in preschool for some additional learning and more science fun. We knew about the 2 hour delay the night before, so we were able to get the dinosaurs in water in advance.
So, we gathered all of our science equipment (some day I should tell you all about what is in our science kit), a plastic bin, warm water, cold water, salt, baking soda, vinegar and boiling water.
Then let the fun begin! It's mostly trial and error to see what happens. We added the baking soda and vinegar so he could see if that chemical reaction would create heat and melt anymore than the same temperature water.
