1 pts

16. Pat has two kinds of plant food: Quickgrow and Supergrow. What would be the best

way for Pat to find out which plant food helps a particular type of houseplant grow the

most?

Look at the advertisements for quickgrow and supergrow, and see which one says it works the

best

O Put some quickgrow on a plant in the living room, put some supergrow on a plant of the same

type in the bedroom, and see which one grows the most

O Put some quickgrow on a few plants, put the same amount of supergrow on a few other plants

of the same type, put all the plants in the same place, and see which group of plants grows the

most

Find ut how much of each kind of plant food costs, because the most expensive one is the

better one for growing plants

Put some quickgrow on a few plants, put the same amount of supergrow on a few other plants of the same type, put all the plants in the same place, and see which group of plants grows the most

Explanation:

In order to solve a scientific problem, a scientific experiment using the scientific method is conducted. In this question, Pat is trying to figure out which plant food (quickgrow and supergrow) makes a particular plant grows the most.

In order to solve this scientific question, Pat needs to set up an experiment by putting some quickgrow on a few plants, putting the same amount of supergrow on a few other plants of the same type, put all the plants in the same place, and see which group of plants grows the most.

The plant grow is the INDEPENDENT VARIABLE i.e. variable being changed while the growth of the plants is the DEPENDENT VARIABLE i.e. variable being measured. Using the same amount of plant grow, same type of plant and placing them in the same place are the CONSTANTS of the experiment.
