In Lockdown some of you learned new skills, one of them being baking bread. In order to bake bread one needs to use yeast -which is a fungi (microorganism) The respiration of all microorganisms results in the release of carbon dioxide. In yeast this is what causes your bread to rise.
You are going to investigate how temperature affects the rising of bread dough. Yeast is a microbe which is added to bread dough. When the yeast cells respire they produce carbon dioxide which makes the dough rise. Respiration is a chemical reaction that happens in all living cells including yeast cells.
