3 Metric SystemExamine the SI units in Table 1(page 50). How many meters are there in a kilometer? How many centimeters are in a meter?
4 Opener What is ONE major benefit to the metric system? How does the metric system work?How have microscopes benefitted you???
5 Metric SystemThe Metric System is the International System of measurement.It is based on powers of 10.Why might it be important to have a universal system of measurement?Scientist need to have a “common ground” for performing experiments.
8 Light MicroscopeLight microscopes have 2 lenses and a source of light.Objective Lens & Ocular LensEach lens has its own MAGNIFICATION.You multiply each lens’s magnification to get the total magnification10x times 40x = 400x
9 Electron Microscope Electrons are shot at the object. Electrons then bounce off, or pass through the object to create an image.Can magnify up to 200,000 times.
