The purpose of this experiment is to discover the effect of temperature upon the rising of bread dough when mixed with bread dough, the yeast converts sugar molecules into carbon dioxide (co2), alcohol cellular respiration [internet. Science experiment: cell respiration – balloon blow up yeast is a single cell organism that metabolized sugar and turns it into carbon. Students cannot directly observe respiration occurring inside living yeast cells, even under a microscope, so they will need to design an experiment to indirectly .
