Eclipses are a relatively rare event and are fantastic learning opportunities  – a timetable is available here  for the next ones . The one on March 20th follows this path

A really useful booklet can be downloaded from the Royal Astronomical Society here (Thanks to Alistair Gittner)

Safety is of paramount importance so please ensure that students are given this advice

Viewing a solar eclipse is potentially hazardous and should only be attempted with caution. You should never, ever – under any circumstances – look directly at the Sun!  – Even when it is partially covered and might not look very bright

Sunglasses will NOT protect your eyes from potential permanent damage from looking at the Sun.

Even worse is looking directly at the sun through binoculars or a telescope, though these can be used safely to project an image onto a card.

Safe ways are outlined below from NASA

Eclipse glasses can be bought ( in bulk ) from here   but quickly to guarantee delivery in time

A box pinhole projector can be very effective – although you may look a little strange ! Instructions are here  A photo or video could be taken by a phone from inside the box

Want to photograph the eclipse ?

There is a very useful article here   Dont destroy your cameras sensor – Use an appropriate filter !

Want to use your mobile phone? It will probably be a waste of time as you will see only a tiny blob. You can take a photograph from the objective of a telescope , but the telescope should be filtered to prevent damage to the cameras sensor . The photo below was taken by  Dean Regas  here
