Materials
  • Large seeds e.g. broad bean seeds, soaked overnight before use
  • Paper and pencil to draw observations
Procedure

Ask students what they might expect to find in a seed (maybe they have already grown plants from seeds, and so have some good guesses).
Students split open their seed and look for the plant embryo: the root, shoot, and the cotyledon where the plant gets it's food from as it germinates.

Notes

Page 10 from the resource book has a good image of the inside of a seed.
