Exploring Melting

Todays experiment is very simple. We made some ice cubes and then put them in different places to watch them melting.

I used lego man shaped cubes just to make it a bit more interesting.


What you need:

  • Ice cubes of the same size
  • Containers for the ice cubes.


  • Place each ice cube in a container.
  • Put the ice cubes in different places, we put ours outside, inside and in the fridge.
  • Time how long it takes each to melt.

First we discussed what makes ice melt and predicted which would melt the fastest.

Can you design a table to record your results?

The Science Bit

Melting is when a substance changes from a solid to a liquid. Water freezes to ice when it is cooled to below 0 degrees celcius, when ice is warmed to above 0 degress celcius it turns back into water.

To expand this experiment you could try the ice cubes in more places, or observe and photograph at 10 minute intervals.

Recording the temperature in each place would also be useful.

Our Results

The first time we did this, the one outside melted faster than the on inside. We decided there could have been a few reasons for this, one being that the outside man might have been a little bit smaller than the inside one, or maybe the wind made it melt faster.

We tried again on a different day and found as expected the man inside melted faster than the one outside.
