by K.J. Price

2. Question: What substance melts ice faster ?
salt
pepper
sugar

3. background
I chose this experiment because i was bored one day and i put salt on ice it started melt. I thought to myself what else could melt ice too?

4. hypothesis
If put salt,sugar,and pepper on ice then salt would melt ice the fastest.

5. variables independent: substance used dependent:
what substance makes ice melt the fastest?
constants:
same ice,same timer

6. procedures Gather materials Set experiment
Put one gram of substance on ice
Time how fast the ice melts
Record times

7. data

9. Conclusion What substance melts ice the fastest?
Put the substance on ice and time how fast it melts.
My data supports my hypothesis because salt melted ice the fastest.
I learned that all substances melt ice at different speeds.
Not all substances are made of the same thing so they melt ice at different speeds.
It took a while to do. next time I would put more of the substance on the ice.
