Make a simple microscope
1. Use two hands, one behind the other, or one up and down, to adjust the distance between them to observe the object until you can see it most clearly. Then remove one lens and observe the object using only one lens. Repeat it several times and see what you find?
2. Move up and down to adjust the distance between the two convex lenses until you find the clearest image of the object. Use a plastic tube to fix the two lenses, and a simple microscope is ready. Try it and see if the image of the object is enlarged.
observe objects around you
Use a homemade microscope to observe surrounding objects. Compared with a magnifying glass, does the magnification of the image of the object increase?
Have we discovered something new? Write down our findings.
Class summary
