Name: ______________
Experiment: Seed Growth
Seeds are the fertilised ova of plants; in the same way a growing human foetus is the fertilised
ova of a human. Seedings require appropriate environments to germinate, which if they don’t
receive, they may not grow as efficiently.
Aim: To investigate different potting conditions and their effect on seed germination.
Make a list of as many factors as you can that could affect the growth of new seedlings.
