The Science of Gardening

This looks best for upper school. The Science of Gardening is a great collection of videos, and interactive activities, about growing plants.
There are three areas: Feed ~ Control ~ Bloom. The first section explores the basics, such as soil types, seeds, and the origins of some of the common cultivated crops.
In “Control”, we find out about biodiversity, growing plants indoors, and plant hybrids, whilst “Bloom” looks at pollination, the survival skills of plants, and why they spend so much effort making themselves attractive.
