Yeast Respiration


How does changing the type of food affect yeast respiration?

Does yeast respiration occur more efficiently at warm or cool temperatures? Follow the lab instructions to answer this question.

Which food type (honey or table sugar) is better for yeast respiration? Design and conduct your own experiment to answer this question.

  • Set up the experiment using warm and cool environments.
  • Collect, record, and graph the data.
  • Draw conclusions based on the data.
  • Design your own experiment using table sugar and honey.
  • Set up your experiment.
  • Collect, record, and graph your data.

Performance Expectations:

MS-LS1-7. Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism.

  • Science & Engineering Practices

    Planning and Carrying Out Investigations - Plan an investigation individually and collaboratively, and in the design: identify independent and dependent variables and controls, what tools are needed to do the gathering, how measurements will be recorded, and how many data are needed to support a claim.

    Analyzing and Interpreting Data - Analyze and interpret data to determine similarities and differences in findings.

  • Disciplinary Core Ideas

    LS1.C: Organization for Matter and Energy Flow in Organisms - Cellular respiration is a chemical process in which the bonds of food molecules and oxygen molecules are broken and new compounds are formed that can transport energy to muscles.

  • Crosscutting Concepts

    Cause and Effect - Cause and effect relationships may be used to predict phenomena in natural or designed systems
