question 17\nread the experiment. then, match the term on the left with its definition on the right.\nkendra is doing an experiment to see which brands of popcorn leave the fewest unpopped kernels. she popped one bag at a time for four minutes each. she tested four brands: jiffy pop, pop secret, great value, and redenbachers. at the end of the four minutes, she opened the bag and counted the number of unpopped kernels, recording the data. she repeated her experiment four times and recorded the average number of unpopped kernels in her data table.\ncontrolled variable\n1. the number of unpopped popcorn kernels\nresponding variable\n2. the brand of popcorn\nindependent variable\n3. the time the popcorn is cooked\ncheck my answer

Answer

Brief Explanations:

A controlled variable is kept the same throughout the experiment, so the time the popcorn is cooked (3) is a controlled variable as it's set to four - minutes for each test. The responding variable is what is measured as a result of the experiment, so the number of unpopped popcorn kernels (1) is the responding variable. The independent variable is what is changed or manipulated in the experiment, so the brand of popcorn (2) is the independent variable.

Answer:

Controlled variable: 3. The time the popcorn is cooked Responding variable: 1. The number of unpopped popcorn kernels Independent variable: 2. The brand of popcorn
