Inquiry Question by Dieshell
-->Why do cities put salt on the streets when it's icy?
Let's say a lady comes out of the store with bag's. There's no salt of the side walk. They ran out of the store than sliped. I don't think the person that own's the store want's to go to cort. Salt melts ice.


Hypothesis by Jessica
If we put ice on hot water then the temperature is going to decrease.

Observations by Esther
0 min Nothing
1 min the salt observe [absorbs] the ice
2 min it melted
3 min it turn to water a little bit
4 min the ice srinked
5 min it turned to all water
Every minute the salt kept on melt into the ice. By the fifth minute it turned to all water. When you feel it it's cold and feels like ice water.

Data by Adrian
Time Temperature
0 min 12°C
1 min 11°C
2 min 8°C
3 min 10°C
4 min 9°C
5 min 12°C
6 min 8°C
7 min 11°C
The pattern goes from greatest to least.

Conclusion by Kelly
Today in science we learned that when you put salt on ice it first hardens then it melts.
