Microscopes 4th Grade NMGK-12 Project #76
Dissecting Microscope • low magnification • approximately 2 to 50 times larger than life • used to see some detail on large objects (whole animals) • use a light source that shines from the top
Dissecting Microscope magnification knob arm eyepiece head objective light focus knob base
Compound Microscope • higher magnification • 40 to 1000 times larger than life • used to view fine detail on small, thin objects • light is transmitted through the object from underneath • usually use a slide to hold object
Compound Microscope eyepiece objectives coarse focus knob stage fine focus knob light base
Using the Microscope • do not move the microscopes • use only the fine focus knobs on the compound microscopes • focus SLOWLY • use both eyes (do not close one)
