Melting Dinosaur Ice Fossils

Melting Dinosaur Ice Fossils

The Primary 3s performed an experiment to see how they could best melt frozen dinosaur fossils.

We discussed the best methods for making the ice melt. The best ideas were to use a hair dryer, hot water, salt or leave it in the room to heat up and finally put it outside in the sunlight. Other notable suggestions were to breathe on them - which would take far too long and warm them up with our hands - but this would be too cold and sore particularly if the ice stuck to your hands.

We talked again about a 'fair test' and how this might work with this experiment.

Everyone made predictions as to which method he / she thought would work the quickest and which would work slowest.

We enlisted the help of principal, Mr Murray to help with one of the hair dryers and put the stop watch on to roughly record our times.

The results were surprising. The hot water worked the best. The ice fossils melted immediate. The salt worked well as did the hair dryer coming in in about 5 minutes. The sun was out but the outside temperature did not help with the melting process. The slowest was the temperature in the classroom.

Our results and conclusions were discussed and recorded and a labelled diagram completed.

To finish off we discussed the temperature the water would fall to in the room if left for a couple of days - room temperature.
