Ice Cubes

Big Question

• My big question is, which chemical substance will melt the ice cube the fastest?

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 .

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

observations

• the salt needed more salt• And the pepper needed more pepper too.

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

Analysis

Yes my test did examine my hypothesis…

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.
