Growth of bean plants – a model for alien life on exoplanets?

OK – this is a bit of a stretch. An experiment we did at home to follow the initial growth of bean plants by photography on our kitchen window at home. Is this a model for alien life? The growth and movement of plants is definitely alien as far as we mammals are concerned – and it is amazing just how fast they grow and the change in position of leaves to point to Sun and between day and night is a lot more than we expected in advance.

The following photo sequence is only over 10 days (it is a reverse sequence with earliest images at the bottom and latest at the top) Рthis has taught the children and me a lot about plant growth and I guess the main reason I am presenting it here is to encourage my astronomy friends to not miss any opportunity to educate our children and the public about the natural world Рall science uses similar principals and all learning improves our ability to understand the world around us and our place within it.
