Experiment: Controlled Ice

Updated: Jul 12

By Mei Yee


For this controlled experiment you just need a few items from around the house.

  1. Cup of cold water

  2. Cup of warm water

  3. Salt

  4. Plate/Tray

  5. Spoon or pipette

  6. Ice Cubes

We used a plate, but you can use a tray or even a muffin pan (then they can be separated if you want to see how much melted from each).


We placed four ice cubes onto the plate; one for the controlled ice cube, second one for warm water, third for cold water, and the fourth for salt.


After we put the water (about 10ml of each) and salt on the ice cubes we waited 30 seconds to see if there had been any changes.


30 Seconds

Not much change happened with the salt and the cold water. So, we added more of each and waited another 30 seconds. We checked it and there was some more of a change, but we kept going at 30 second intervals.


90 Seconds

At 90 seconds you could see more of a difference in all of them.


We hadn't seen salt on ice up close like this so we all thought it was interesting as to how it affected the cube.

The one that had salt on it

We also noticed the bottoms looked different, so we turned them over to see the differences.
