More about these tools

Name it lights a ring for you to identify, from four choices or by typing. Study switches the labels on and adds a line on what each part does. Any drawing prints blank as a worksheet or labeled as the answer key.

Begin with the compound microscope. The other microscopes follow, so the differences stand out. The measuring tools, such as the micrometer, the dial caliper and the triple beam balance, are drawn with their scales in view. The bench equipment, such as the Bunsen burner and the micropipette, is here for the part names only, and your own lab's safety rules come first. Every part name was checked against at least two references.
