What reading level is Light a Series of Simple Entertaining And Inexpensive Experiments in the Phen book?
To quickly assess the difficulty of the text, read a short excerpt:
Just behind this focus we place a glass slide, contain- ing some object to be examined in a microscope. To hold this slide upright, we stick it in a mass of wax. The magnifying-glass is fastened to a bit of wax resting on a block of wood, so that it may be moved backward or forward along a strip nailed down on another block. About 15 feet (4*57 metres) from the table is placed a screen, and on this is projected a large image of the minute object on the slide. A cloth is hung over the upper part... of the water-lens, to shut out the light, and all other light is excluded from the room. This apparatus makes a solar micro- scope, that may be used to project all kinds of micro- scopic objects, so that they can be exhibited before a large number of people. Tanks for holding animal- cules, and all objects used in microscopes, may be placed in this solar lantern and exhibited upon a large scale, with very little trouble, and at only the ex- pense of the flask, the pocket-lens, the screen, and the heliostat.
