How do snowflakes form ?

With snow forecast for some areas at the weekend - including Norfolk, although it's not looking like it at the moment - the sky is blue and the sun is shining, although it is bitterly cold out there. About to head out on the school run and going to wrap up warm !

I have been working with TWIG Science films in the last few months on their Human Geography films, and am also going to be working on some Earth Science materials for them in the next month or so. Their films won the best Secondary Digital content award at BETT.

Now there's a new free film to view which explains how snow forms. Check it out as an example, but remember that the picture quality of the films on the main site is even better.

Check out Twig as a possible addition to your geography department's resource bank.
