Aim:

To observe the change of state of ICE.

Prediction:

We think that ice will melt in 5 minutes. It will not change colour or make any sound. It will turn into cold water.

Materials

Make a list of what

was used.

Materials:

Block of ice (1/2 cup)

Plate

Camera and tripod

2 lamps

Water bottle

Plastic cup

Stop watch

Method

What did you do?

Method:

1. We half filled a plastic cup with water and froze it overnight.

2. We tipped the block of ice onto the plate.

3. We put the lamps facing the ice.

4. We took photos every two minutes until the ice melted.

Results

What happened?

See

Smell

Time

Insert your

visual record.

Results:

We watched the ice melt.

While the ice melted, it moved on the plate and made a small cracking noise once.

The ice took 53 minutes to melt.

There was a plate of water at the end. Click in blue box to play.

Conclusion

How did your results

compare to your

predictions?

Did anything go

wrong?

Why did this happen?

What could you have

done differently?

Conclusion:

The ice took a lot longer to melt than we thought, even though we had lamps on it.

It made a noise and moved because it was contracting.

It did turn into cold water when it melted because the room was warmer than the freezer.

Reflection

What did you learn?

What would you lik

e to

find out about?

How could you do

this?

Reflection:

I learnt that because lamps are warm they make the ice melt, and warmer temperature causes a solid to change into a liquid.

I want to know …..

Why don’t icebergs melt?
