In Year 7 Science pupils observed the cooling of stearic acid. The class were set with the challenge to answer the following questions:
- When a substance cools down and reaches a temperature below its melting point, it will change from a liquid to a solid. But what happens during this cooling process?
- Is it possible to find out the melting point of a substance by observing it as it cools?
Year 7 thoroughly enjoy the hands-on approach to learning how a scientific inquiry is carried out.
