are micro-organisms fun?!
my 9 year old daughter has to do a 5 minute presentation on micro organisms!
She throws herself wholeheartedly into this kind of thing - usually! But we are really stuck on how she can make it an interesting presentation, and also be informative.
Does anyone know anything fun or unusual about them?

More than one kilogram of a human's mass is made up of microorganisms.
Microorganisms have been found living at depths of over a kilometre below the bottom of the ocean floor.

When they were first observed, nobody at the Royal Society of London (the leading scientific establish of the day) believed they existed.

A bit high brow for a nine year old but could be good if reworked.
All multicellular life is composed of cells that are the result of an endosymbiotic relationship between two ancient microorganisms. Without the mitochondria living inside eukaryotic cells, large lifeforms would be impossible.
