Students do a draft audit at home.

  • Grade Level: K-3
  • Subjects: Science, Social Studies, Art


  • Pencil
  • Tape
  • Plastic food wrap


Students will learn an easy technique to find drafts in their homes and classrooms.

  1. Cut a 12cm by 25cm strip of plastic wrap.
  2. Tape the shorter edge of the wrap to a pencil and let the rest hang freely.
  3. Blow plastic wrap gently and note how sensitive the wrap is to air movement. Drafts mean that air is leaking into or out of a building. This means either a loss of heat in winter or a loss of air conditioning in summer.
