Bubbles in Your Bread


Baking bread is something many people all over the world do every day. Have you ever baked bread using yeast? Did you know that yeast are living organisms? In a water environment, yeast use sugar and oxygen to produce a gas called carbon dioxide, CO2. The carbon dioxide makes the dough rise and creates the bubbles or air pockets that you can see in the bread that you eat.


In this activity, you will

  • Use a Pressure Sensor to measure the pressure caused by the production of CO2.
  • Make observations about how temperature affects rising dough.
