1-4 Microscopes

Explore microscopes! Label parts, calculate magnification, and learn about different types. Fun science worksheet!

Microscope notes Record your notes in your digital interactive notebook. Label the parts of the microscope write it exactly like it appears in the word bank OR cut and paste. eye piece body tube arm stage coarse adjustment knob fine adjustment knob base light source diaphragm stage clips objective lens objective lens objective lens revolving nosepiece Total Magnification on a Compound Light Microscope Calculate how much a specimen is magnified in TOTAL with each objective lens in place. Objective Objective Lens Magnification Ocular Lens Magnification Total Magnification Scan Objective 4 10 40 Low Objective 10 10 100 High Objective 40 10 400 Microscope Function Match the microscope parts to their definition. eyepiece lens The lens you look through – normally 10x magnification coarse focus adjustment Large changes in focus- use only with scanning (4x) and low (10x) fine focus adjustment Small adjustments to focus- use only with high power (40x) base The bottom of the microscope used for stability objective lenses 3 lenses that rotate and help increase magnification –usually 4x, 10x, and 40x magnification stage Where the slide is placed diaphragm or iris Varies intensity of the light projected upwards onto the slide light source Sends light onto the specimen Types of Microscopes Match the microscope, image, and definition. Light Microscope uses light magnifies less speciment can be living simple with one lens or complex with 2 lenses used in high school science lab Electron Microscope uses electrons magnifies more specimen have to be dead SEM (scanning electron microscope) TEM (transmission electron micoscope) expensive
