Can Plants Reproduce by Breaking Apart?

intended for grade 3 (to 6)


  1. Question: Will broken branches of a plant grow in new plants?
  2. Hypothesis: parts broken off a plant can grow into new plants,
    I have observed willow trees on new sandbars created by floods on a river. These willow trees appear to be too old to have grown from seed after the flood.
  3. alternate hypothesis: parts broken off a plant should die.
  4. State what observable event is expected to occur because the hypothesis is true:
    a branch cut off a willow tree, and 'planted' in water will become new plants.
