1. Ice Cubes

2. Big Question
My big question is, which chemical substance will melt the ice cube the fastest?

3. Hypothesis
My hypothesis is that the salt will melt the ice cube the fastest
I think salt will melt the ice cube the fastest because it has carbon and hydrogen and oxygen in it .

4. Interesting facts The coke didn’t do any thing to the ice cube
The Pepsi didn’t do anything either
The pepper melted some of the ice cube
The salt made holes in the ice cube
the vinegar melted a little bit of the ice cube

5. Materials 5 ice cubes 5 cups (clear cups) Salt Pepper Coke Pepsi
vinegar

6. Steps 1. put coke in one cup 2. put Pepsi in one cup
3. put salt in one cup and pepper in another one
4. put vinegar in the last cup
5. Wait till they melt

7. References

8. observations My observations were that the vinegar needed less vinegar
the salt needed more salt
And the pepper needed more pepper too.

9. data My data is that the vinegar was in 1st place the salt was in 2nd
The pepper was 3rd
Pepsi was 4th
Coke was 5th

10. Analysis
Yes my test did examine my hypothesis…

11. Conclusion
No my hypothesis was incorrect because vinegar melted the ice cube the fastest.
I would change the part where I put Pepsi in the cup, I would of put grinded up coffee beans in the cup.
my new questions would be: would salt and vinegar melt an ice cube together or will sugar and grinded up coffee beans melt the ice cube the fastest.
