Doodle Science - May 2014



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



Chimera

Fire from the ground. This is the Chimera in southern Turkey, on a hill side natural gas comes out of the ground and burns, and apparently it has been doing that for at least the last 2000 years. There are several vents and the particular geology of the area causes it. The name is from the mythical beast slain by Belerophon that according to legend had the head of a lion, the tail of a serpent and was goat in between. I got this photo at Easter.

Great Dates in Sci and Tech for May

29th 1919 ~ Arthur Eddington takes measurements of stars during an eclipse to test Einsteins theory of relativity.

Using biscuits for material testing


Different biscuits have different structures, honest they do, you can test them for strength or tension and compression,

"bendability" but my favourite is to dunk and see how long it takes them to fall apart.

Which will survive longest, a rich tea or a ginger nut?

Lots of possible variables and they make quite good models for looking at rock types too.

Health and safety: The bickies are experimental equipment and not just for eating.

Some thing else to try Make your own biscuits for testing, do some edible chemistry.

Wonderful Cephalopods, Well worth a look, I met some while snorkelling and I am never eating Calamari again.
