Seed Germination 2

As I peeled the beans for experiment 2, several beans broke apart. I wondered if the broken seeds would germinate and grow enough to emerge as seedlings, and for that matter, how small a part of a seed could survive to become a seedling. I thought that half a seed might survive, but less than that I fully expected to die. This experiment seemed to be more interesting than the first formal science experiment I ever designed, so I designed my second formal science experiment, without waiting to see the results of my first experiment.

intended for grade 5 (to 8)

Introduction

  1. Will part of a seed grow?
  2. I really don't think that this will work.
    I suspect that it takes a whole seed to survive, although maybe half a seed can survive.
  3. (no entry)
  4. If the hypothesis is true, then the parts of seeds will not emerge as seedlings.
    The whole seeds will emerge as seedlings.

Materials and Methods
