Water-fleas are easy to find. Most ponds will provide enough of these small crustaceans. They are ideal subjects for study under the microscope. You can examine them swimming under a low power stereo-microscope. When observed with stronger magnification it is best to use a deep slide. You can add dots of vaseline to the corners of the coverslip to prevent the water-flea being damaged. It is wonderful to see the heart beating and the blood flowing!
