Pls hurry im doing an exam Four groups of students plan scientific investigations to answer four questions for the science fair.
mafiozo [28]

Answer:

The correct option is 3

Explanation:

An experimental investigation would require an hypothesis, aim, methodology, results, discussion and conclusion.

The third option can be easily answered using the "requirements" above.

The hypothesis (null hypothesis) would be different types of grass do not affect how far a ball rolls

The aim would be to determine the effect of different types of grass on the movement of a ball

The methodology would involve identifying several playing grounds with different grasses and then rolling the ball with a constant force on the different grasses and then determining the eventual speed and distance traveled by the ball on those grasses which would serve as the results. Inferences can then be made from this results and then conclusions drawn subsequently.
