Students do a draft audit at home.
- Grade Level: K-3
- Subjects: Science, Social Studies, Art
- Plastic food wrap
Students will learn an easy technique to find drafts in their homes and classrooms.
- Cut a 12cm by 25cm strip of plastic wrap.
- Tape the shorter edge of the wrap to a pencil and let the rest hang freely.
- 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.
