For an elementary school project, I'd like the children to take apart some
old electronics to get an idea of how things work, what goes into each
product, etc. My question is: Are there certain electronics or appliances
we should stay away from because of chemicals or something else that would
be unsafe for the children? Please advise.

Caution them to keep their hands out of their mouths until they have
washed them, and make a particular point of warning them about lead,
which is in most solder.

Otherwise, go for it.
