Doodle Science - February 2013

Circulated to schools, organisations and individuals - covering primary science and related bits and bobs.
Something warm and dry to make you think of summer in this damp and cold month. This is a cactus garden on Tenerife I was lucky enough to visit a little while ago. Lots of the plants were not in fact cacti, which only come from the Americas, many were spurges or euphorbias which through the wonder of convergent evolution look just like cacti but come fro the old world. The conditions they live in makes the the succulents of both places end up looking very similar. The Euphorbias are the biggest single genus of plants and some grow wild in this country look very different to their tropical cousins but the flowers are very similar.

Something to try.(provides you have an android or smart phone.)

There are some brilliant apps and these ones are free too.
Google Sky Map shows the sky as it actually is and as you move the phone the view you get changes,
well worth a little memory space.
Another cracking one is the iGeology 3D from the British Geological survey, .which gives a 3 dimensional geological map, amazing, especially if you like rocks.
Guess who just got a new phone.
Interesting 2 Leonardo codecies on line echalk has some interesting resources.
