He decides on an experiment where he will feed it the very best canned food plus a dietary supplement of vitamins recommended by a veterinarian. Which of the following best describes Ruben's project?
A) This is an example of an excellent, controlled experiment as it is written. B) Ruben needs to take careful measurements of the puppy's weight and height at least once a week for it to be a good experiment. C) Ruben needs to control for the amount of exercise, sunshine, water, and care that the puppy gets each week, so that they are equal from week to week. D) Ruben needs to use his mother's 6-year-old chocolate Sharpei to feed a standard diet so he can compare his puppy with a control dog. E) This is not an experiment–there are no controls or replicates. Title: Re: Ruben has a new puppy and wants to feed it the best possible food.
