Collect the pond water. Obviously, pond water comes from ponds, but if there are no ponds nearby, water from a lake, river or stream will suffice (water from these sources will have many of the same organisms as pond water). Simply go to the water and collect a small amount in a lidded container. Seal the container with its lid, and take it back to the microscope.
Prepare the slide. Preparing the slide means to put the pond water onto a microscope slide in a way that it can be viewed through a microscope. First, suck up a small amount of the water in the container with an eye dropper. Then, carefully release the water onto a microscope slide. Once the water is on the slide, use a slide cover slip to cover it. This will spread the water out into a thin layer over the slide. Check to see if there are any air bubbles. If there are, carefully push them from beneath the slide cover slip.
Place the prepared slide securely into the microscope's viewing area. Then, activate the microscope's light source and look into the viewing mechanism. Use the dials on the microscope to adjust the focus and move the slide around. Most microscope controls are fairly intuitive, so it should not take long to adjust the microscope to the correct settings.
