We are studying a bit about fire and ice this week. So, I thought it would be a great idea to demonstrate how salt melts ice. We have many salt trucks driving on our freeways and side streets during the winter spreading salt all over the roads so we can drive safely without sliding into another car or pole! I explained to my littles what the trucks do and why it's important to us. They were absolutely fascinated by what I was telling them. They asked lots of questions and had lots of ideas! Some said "I think the salt is eating the ice." And, "I think the salt gets really hot when it touches the ice." Check out the pics...
|we started out with 3 ice cubes and 1 tablespoon of salt...sprinkling the salt on a little at a time.|
|some ice started melting right away!|
|others took a little longer to melt...|
|if nothing else...it was sure fun to play in the salt piles and water puddles :]|
A hint or 2 - Keep hands away from the eyes when working in the salt. One of my little guys tried to itch the side of his nose and got some salt in the corner of his eye, he was tough and didn't cry but it was super irritating for him! Also, I thought it would be fun (if I would have thought about it before hand) to either color the ice cubes before freezing them or even to color the salt. Maybe bigger ice molds would have been better too? No matter what it is a fun project!
Happy winter days!
