Doodle Science - June 2015

Circulated to schools, organisations and individuals - covering primary science and related bits and bobs.

Oak apples

Oak Apples, galls formed by Biorhiza pallida, a tiny little gall wasp. The galls have many chambers inside of which the insects live, secreting a chemical that makes the plant grow the galls and feeds them too. Often they are on little trees that are struggling a bit and whose immune system is a bit challenged, so if you find one you will find a lot. The galls are very high in tannin so they used to be collected to make ink, I think it could be interesting if only I had the time.
