Primary - Useful Microbes: Alternative

The Useful Microbes section of e-Bug, highlights to students that not all microbes are harmful by examining the various ways and means we use certain microbes for our benefit. In the main activity, Yeast Races, students observe first hand how microbes can be put to good use in the food industry by carrying out a fun experiment to observe how yeast makes dough rise through the process of fermentation. To reduce the amount of photocopying required, the Student Handouts for this section are also available in an MS PowerPoint presentation for whiteboard use.
