introduction to how things work together in an ecosystem.
There are five key ingredients in good soil, namely:
The following video (6:23) specifies the first four of these ingredients and then adds the 'FBI' (i.e., fungus, bacteria and invertebrates) for the organisms.
The direction of fluids is discussed in this video (5:23)

The following video (1:33) features Roman aqueducts and some of the engineering principles behind them.
Aqueduct construction activity.
