One of the best ways to study seeds is to take them apart! So let’s get started with that dissection.
What you’ll need

• Use a butter knife to carefully pull apart your
• Have the kids examine them and draw what they
• Compare the sprouted beans vs just the soaked

• Compare the seeds to this seed diagram and
identify the parts.
Hilum: scar mark from where the seed grew
Cotyledon: usually becomes the 1st leaves of a
