keep it in a place where it will receive light (but not direct sunlight).
In about five days, you may examine the water. First make a special slide: Using a toothpick,
make a ring of petroleum jelly on a clean slide. The ring should be smaller than a cover slip
and be about half as thick as a slide.
Put a drop of water from the jar onto the slide Inside the ring. Use the lowest power of your
microscope and write down your observations. Did you defect any movement in the water?
The movement is caused by microscope animals. Try to focus on one the animals
– this may
not be very easy as a drop of water is like and ocean to a microscope creature.
If the animals seem to be moving too fast to study or don't stay in focus for very long, soak up
a little bit of water with a corner of a paper towel.

Remember you can make a specimen slide out of almost any material. When you are on a
playground, at school in a park, or just sitting around at home, train yourself to look at all the
material around you. Keep an eye out for what might make a good specimen and discover the
hidden microscopic world that surrounds us all.
