Answer:
Grow two Elodea plants for testing hypothesis.
Explanation:
Take two pots both having Elodea, a freshwater plant. In one pot fresh water is applied to the plant while on the other hand, slightly acidic water is supplied to the other pot. Maintain all environmental conditions similar to both of them in order to gain accurate results. If both plants grow at the same rate then the hypothesis is wrong whereas, if the growth of a plant having acidic water stunted in height as compared to other plant so we can say that the hypothesis is right.
