Then we added a few drops of water
and put a slide on top of the water.
Then we put it under the
microscope and we saw that the
starch looked like a shell. After that
Mrs. Kotnová showed us some
pictures of different experiments
under the microscope that looked
like art. She told us that the
microscope was very expensive,
600 000 Kč or 24 000 euros.
Microscope
Mrs. Pavla Kotnová, also chemistry
and biology teacher, showed us
samples of sugar, salt, caffeine and
vitamin C. We examined them
under a microscope and changed
the light and the colors on the
monitor. The crystals of the salt
looked like a shape of a octahedron.
Then we made our own sample of
starch from potato. We cut a slice of
it and spread it on the slide of glass.
