Dissolving!

In Science we have discovered what the differences are between a solid,liquid and a gas, and that is possible change the state of them   .  We wanted to experiment with this concept so we  decided to focus on dissolving and chose jelly as our solid.

We had 4 different experiments:

1. Hot water and a jelly cube

2. Cold water and a jelly cube

3. Hot water and a cut up jelly cube

4. Cold water and a cut up jelly cube

Can you guess which one dissolved the best?
