Why is salt put on roads when it snows?

Last week we explored the question, "Why is salt put on roads when it snows?"
The students listened to informational articles, watched a video, and performed an experiment with ice and salt. 

We found that the salt makes the water temperature rise, which causes the ice to melt. The salt looked like it was eating away at the ice. This was a neat experiment!

Have you ever wondered how birds survive the coldest winters? Stay tuned...
