MAGNETISM

A Few Dont's for Young Students.

Don't fail to make at least a part of your own apparatus; there
is a great deal of satisfaction and pleasure in home-made
apparatus.

Don't experiment in all parts of the house, if working at home.
Fit up a small room for your den, and carry the key.

Don't begin an experiment before you really know what you are
trying to do. Read the directions carefully, then begin.

Don't rush through an experiment to see what happens at the end
of it. See what happens at each step, and notice every little
thing that seems unusual.

Don't try to do all parts of an experiment at the same time.
Understand one part, then proceed.

Don't fail to ask yourself questions, and form an opinion about
the results of an experiment before you read what the author
has to say about it.

Don't fail to keep a note-book. Keep all the data and
arithmetical work for future reference.

Don't leave the apparatus around after you have finished the
day's work.
