Science and Agriculture in the Kitchen

After eating a papaya, the kids were fascinated by the many bright seeds. Instead of dispensing with them, we made an experiment:

First, we wondered what to do with the seeds - should we sow them as they are, or maybe wash and let dry? We washed about a half of the seeds and put aside to dry, as seen in the photo above. Next we turned to think about the conditions which would best allow the seeds to germinate. The kids raised various assumptions, according to which we filled five different glasses: one with soil and lots of water; another with soil and just several drops of water; one with moist cotton wool, etc.

Once the seeds we put aside have dried, they too will be put in five glasses in similar conditions.

The kids are following the seeds with interest; what's your guess - which seeds have a chance to germinate?
