You Can Experiment With Hydra


You, too, can try your hand at repeating Abraham Trembley's experiments or see if you can devise some of your own. At the least you can attempt to observe the eating behavior and different methods of locomotion this animal exhibits. These animals make great subjects for science fair projects.

First, find a sunlit pool or pond and take several samples of water and aquatic plants in jars. Put the plants and water into a white bowl so you can easily see the hydras. You can carefully collect them with an eye dropper and place them in a suitable jar or small aquarium for observation. All you need is a good magnifying glass and patience. Be sure to record your observations and experiments. Also, be sure to repeat them, as Abraham Trembley did.

To feed your hydras, any of a number of minute animals may be used. These would include brine shrimp larva, Daphnia, Cyclops, copepods, Gammarus, Tubifex worms, etc. These can be obtained from a pond or a tropical fish store. Have fun!
