The video above is a basic and short guide to ponds, aimed at schools. It was produced by the British Ecological Society (BES), which is currently celebrating it’s centenary.
BES also provides some interesting educational resources on the ecology of ponds, describing both the main ideas as well as some experiments. The material covers: acid attacks, blooming algae, designing keys, getting oxygen, photosynthesis and water biochemistry.
On this theme, Fleet Pond Society formally opened the pond dipping platform in May this year and here’s a post on it’s use in practice (see also photo below).
