Answer 1

Raul wants to study how pot size affects the growth of plants. To do this, he intends to purchase three different pots of varying diameter. Then, he will fill each pot with the same amount of soil and plant different kinds of flowers in each pot. Finally, he will place the pots side by side in a sunny location and water each pot daily with the same amount of water.

Will Raul's experimental set-up produce valid results?
Yes; Raul set up his experiment correctly so the results will be valid.

Yes; Raul has a testable hypothesis so the experiment is valid.

No; Raul doesn't have a testable hypothesis so the experiment is pointless.

No; Raul changes more than one variable so the results will be invalid.
