Yeast Balloon: Measuring Respiration

Use yeast, sugar and a balloon to measure how temperature changes the amount of gas living cells make.

Grade 8ExperimentScienceBiologyChemistryData AnalysisIntermediate45 to 75 min8 materialsAdult supervision required

What you'll learn

  • Describe cellular respiration and fermentation in simple terms
  • Measure balloon circumference as an indicator of gas volume
  • Use data to describe how temperature affects living things

Objective
