Discuss
..... all kind of practicable changes and measures that could be done to keep the heat of the tea. Find out if the changes or measures really work (see procedure above).   If it works write it down and report it all to our database. 

Surely students in different countries have different and interesting ideas about how to keep the energy in a cup of tea, ideas that other students can enjoy and find useful. 


The idea about the cup of tea and the discussions and laboratory work around it can be applicable to any other model for example an aquarium, a vivarium, a model of a house, a vehicle, a machine, an ecosystem.

 

Keeping the heat or high temperature in a cup of tea means saving wood, saving timber or fossil fuels and in the long run - reducing the amount of greenhouse gases.
