We have been exploring solids, liquids and gases. One of our experiments was to predict, observe and explain the fastest way to melt an ice cube.

In groups, we chose 4 strategies to melt ice cubes.

1. Suck it in your mouth

2. Pour cold water over it

3. Pour hot water over it.

4. Crush it with your hand.

(Other noteworthy suggestions were: leave in sun, wrap in paper towel, blow with hair dryer, hit it with a hammer!)

Our results showed that in every group pouring hot water over the ice cube worked the best. Some of the explanations as to why included:

The heat from the hot water melts the ice.   The pouring motion helps it to melt.     The hotter the water, the quicker it melts.

Here are some images of our experiments.
