In our science lesson this week, the pupils were asked; Which cup would keep a hot drink hot the longest?

We worked as a class to plan an investigation to decide on the best material to make a cup for a hot drink: plastic, metal, cardboard or ceramic. After discussing how to make the test fair and making a prediction, we put hot water (75 degrees C) in each of the four cups and measured the temperature - using a thermometer - every two minutes.  Although it was quiet close, the cardboard and plastic cups kept the water the warmest, whereas the metal and ceramic mugs allowed the water to cool. This is because cardboard and plastic are insulators of heat, but metal and cermic are conductors of heat.

In conclussion, if you want to keep your brew warm, use a plastic mug!
