QUESTIONS & ANSWERS
A botanist wants to determine if environmental temp affects root growth. In her
experiment, she creates 4 rooms at temp that very by 5 degrees F. Each room gets 20
seedings of the same species, which she grows on agar plates for 60 days. Once a day,
she measures the length of each seedling's root. At the end of the 60 days, she
compares the length of the roots w/ the room temp. She finds the room with the lowest
temp produced the longest root. What is the independent variable in this study.
Temp
Seedlings
Light
Root Length - ansTemperature

A vet student designs a study to examine the nutritional qualities of dog food. She
believes that a grain-free diet can affect dog health. She selects 3 of the top-selling dog
food brands for her study. From a local humane society, she selects several Chihuahua
puppies under the age of 1 year. She will track these puppies for the next year and
access their health, include weight, complete blood count, and paw size. Three puppies
will be fed nothing but brand #1 dog food, 10 puppies will only be fed Brand #2, and 10
puppies will only be fed brand #3
What is the independent variable in this experiment ?
