Biology Lab Tips for Transpiration

  1. Use house plant if bush beans are not available.
  2. Cut plant stems and insert stem into tubing while stem is submerged in a pan of water. This prevents air gaps from forming in xylem vessels.
  3. Buy disposable glass pipettes (and reuse).
  4. Preparing stem cross section can be optional.

Before introducing experiments for biology science fair projects make sure you define important terms like transpiration.
