TIP!
This is how
to use the pipette!
EXPERIMENT 1
EXPLANATION
You see the letters of the newspaper
enlarged as if by a magnifying lens. Your
microscope works by the same principle
as this “two-drop microscope.” Instead
of the water drop lens, your microscope
has plastic lenses installed in its optical
tube, and the viewed object lies on a
slide clamped in place beneath them.
Water drop as
“magnifying glass”
YOU WILL NEED
› slides, pipette
› 1 glass of tap water, 1 newspaper
HERE’S HOW
1. Use the pipette to place a drop of water on
the slide (see illustration) and carefully set
the slide on the newspaper. Now look through
the drop at the newspaper page.
2. Next, place another drop of water on the
second slide and hold this second slide above
the first one in such a way that you can look
through both water drops to the newspaper
beneath them. Can you find the optimal
distance between the two slides that will
make the writing appear even more enlarged
than when you use just one?
An experiment to help you
hit the ground running
