Many plants can affect the growth of other plants near them. This can occur when one plant produces a chemical that affects another plant. Design an experiment to determine if a solution containing ground-up goldenrod plants has an effect on the growth of radish seedlings. In your experimental design be sure to: state a hypothesis to be tested [1]• describe how the experimental group will be treated differently from the control group [1]• explain why the number of seedlings used for the experiment should be large [1]• identify the type of data that will be collected [1]• describe experimental results that would support your hypothesis (1) -
