Aim:
Our aim for this science experiment was to melt ice which we oppose ‘Dry Ice’ This experiment was also a part of our Education Perfect learning as well, because we will start to focus our learning on what we have been learning about.

Method:
Equipment:
- Beaker
- Bunsen burner
- Matches
- Ice
- Salt (optional)
- Gause mat
- Heat mat
- Tripod
- Thermometer
- Retort Stand
- Clamp
- Timer or stopwatch
- Safety glasses
Instructions:
- Get equipment ready and be safe.
- Set up the Bunsen burner, but do not light it.
- Fill half of your beaker with ice and add a 50mL of water.
- Set up the stand, clamp and thermometer.
- Make sure the thermometer is not touching the bottom of the beaker.
- Measure the temperature of the ice.
- Light the Bunsen burner and heat the ice with a blue flame.
- Start timing.
- Every 30 seconds, record the temperature of the ice/water.

Discussion:
What happened?
The ice that was put in the beaker turned into a liquid due to temperature changes. The state changed because we heated the ice and it had higher energy compared to the ice where it had lower energy.
Water can melt at the same temperature it freezes, but at room temperature it will slowly reach it’s liquid state.
The 3 states of matter and their transitions.
There are 3 states of matter, solid, liquid and gas.
When the water particles are frozen, they vibrate slowly and have many bonds meaning this is solid. But as you slowly heat the frozen particles up it would vibrate more and the bonds will move over each other, this is reaching their liquid state, but when you heat the liquid more, it turns into gas which means their bonds are broken and they can move freely.
