Microscopes is an easily understood, colorful introduction to an important and commonly used scientific instrument. Young readers learn that some objects are too small to be seen with the eyes alone, for example, red blood cells and atoms, but a microscope can be used to magnify these to a size that can be seen. A light microscope is illustrated, showing the lenses that magnify the sample, the stage that holds the sample, and the light that illuminates it. Red blood cells can be seen with a light microscope, and there are other types of microscopes that can be used to see smaller things, even atoms. Some microscopic photographs are shown.
A pronunciation guide of scientific terms is included. 24 pages. Reading Level 1-3. Interest Level 2-5. Lexile measure 450L.
