The teaching methods provide teachers with all the important information on using the worksheet of the same name and the related incremental hints in class. The task is about recognizing the principle of the conservation of mass in chemical reactions. The background on the task and possible variations are provided.
The five incremental hints for the task are provided with the corresponding answers. They are also available as a separate ready-to-print medium named “Does combustion make things heavier or lighter? (hints for printing)” or as an interactive medium named “Does combustion make things heavier or lighter? (interactive hints)” on the media portal of the Siemens Stiftung.
