Title-The Effects of pH Level on the Growth and Regeneration of Hydra.

Hypothesis- The hypothesis of this experiment is that the hydra will not grow as much or regenerate as fast if the pH level is low or very acidic.

(I.V.)- The pH level of the water.

(D.V.1)- The amount the hydra grows .

(D.V.2)- How fast the Hydra regenerates.

Constants- Sunlight, temperature, amount of water, type of hydra, size of culturing dish, type and amount of food.
