Sabrina wants to test which brand of popcorn pops the most kernels. She picked a store brand, Orville Redenbacher, and PopSecret. All three bags started with the same number of kernels. She popped each for 3 minutes in the same microwave, and then counted the number of kernels left over. What is her independent variable?
Number of kernels left over
Brand of popcorn
number of kernels before popping
length of time cooking
Kira wants to test which type of soda creates the biggest foam explosion when adding a Mentos candy. She chose Sprite, Coke, and Mountain Dew. One at a time, she added a single Mentos candy and measured the height of the foam eruption. Mountain Dew created a foam eruption of 7 inches. Coke and Sprite tied at 5 inches. What is her dependent variable?
Brand of soda
Number of mentos candies used
Height of foam eruption
Temperature of soda
