Eclipse-viewers are the safest . . .
Share viewers but don't fight over them!.
For tips on safe viewing (and alternatives to eclipse-viewers), go here
Viewers can be shared.
To plan for this:
- find out how long the eclipse is in your town with this calculator;
- decide how long you want each class to be outside for: a quick 10min look, or will you let them make and photograph pinhhole-projection eclipse art?
- how many viewers will you need for each class? It takes just a few seconds to look at the eclipse
- what will you do during break? can you distribute the viewers among the teachers on duty, so learners can get another look?
- plan on checking that viewers have not been damaged by learners - remove any that have torn or missing filters.
A school in Rustenburg (South Africa) has 26 classes of about 30 learners per class.
The eclipse-calculator tells them:
They decide to aim for eclipse-viewing from 10am to 12noon - two hours. There is a half-hour break at 11am,
so viewing time is reduced to one-and-a-half hours.
They decide to get one eclipse-viewer per three learners - ten for a class of 30. So if one or two get damaged (from learners fighting
over them), it's not a disaster.
They consider the following options:
- half-an-hour per session, three sessions total, nine classes per session, ten viewers per class - 90 viewers for the school;
- fifteen minutes per session, six sessions total, five classes per session, ten viewers per class - 50 viewers for the school.
The teachers decide they would like the learners to spend enough time outside to make and photograph pinhole projection art, but that
they don't want to spend too much money on viewers, so they decide to:
- take nine classes out at a time for half-an-hour each,
- buy just forty viewers - ten of these will be kept as spares, the other thirty will be divided into batches of ten and passed around from class to class
while they are outside;
- keep the learners busy with pinhole projection, with class teachers supervising; some parents will be invited
to help with supervision and encourage the learners;
- assign three senior students as "runners" - each will be responsible for making sure one set
of ten viewers gets passed around to three classes per session; they will also check the viewers between groups, and throw
out any that have been damaged;
- during break, share out the viewers among teachers and responsible older learners, who will spread themselves out around the grounds,
and let learners have another look at the eclipse.
