What reading level is First Lessons in Physics for Use in the Upper Grades of Our Common Schools book?
To quickly assess the difficulty of the text, read a short excerpt:
" Bead " Color, " in "The Earth and its Wonders. " 140 FIRST LESSONS IN PHYSICS.
LESSON XXXVII.
CHEMICAL ELECTRICITY.
71. EXPERIMENT. Take a plain glass tumbler, and place in it a porous cup of earthenware (un- glazed) in a manner such, that between the cup and the tumbler there is a finger's width of space left. Next have a small sheet of zinc cut as high as the cup. Then bend it into a cylinder wide enough to encircle the porous cup freely. This cylinder is open above and below, with a slit t...hrough its whole height. On the top, and oppo- site the slit, about a square inch of zinc is left higher than the rest. To this piece, one end of a copper wire about a foot long is soldered. The zinc cylinder is put into the space between the tumbler and the cup ; the space is then filled with diluted sulphuric acid (a table-spoon full of the acid mixed with ten times the quantity of water). The cup is filled with strong nitric acid. In the acid place a plate of carbon, to the top of which the end of another copper wire is secured.
