Blackfell Primary School

In Science, we have been learning about Living Things. This week, we learned about micro-organisms and how some of them are helpful while others can be harmful to us. We looked at how yeast is used to create air bubbles in bread to make it rise. Together we planned an investigation into which temperature of water would be best for yeast to produce the most air bubbles. We tested cold, warm and hot water and found that warm water completely filled our bottle with bubbles and inflated the balloon the most. This means if we want to make dough for bread, yeast needs warmth to produce bubbles and make the bread rise.
