Hello,

This sounds like a fun project! Salt helps melt ice by lowering the freezing point of water. This is the temperature where water changes from a liquid (water) to a solid (ice).

This article talks more about salt (NaCl) and ice (H2O) and might be helpful: https://www.sciencebuddies.org/news/article?id=104697

Good luck,
