Jason wanted to find out how he could increase the number of popcorn kernels that pop when cooked. He hypothesized that more kernels would pop if he used more oil. To test this, he placed 100 kernels of “Pop Rite’ popcorn into a popcorn popper that contained different amounts of oil. He used the following amounts of oil: 5 ml, 10 ml, 20 ml, and 30ml. He used 5 ml of oil as the control. He conducted the test 3 times for each amount of oil. He then counted the number of kernels that had popped. Each time he heated the oil for 2 minutes and cooked the popcorn for 4 minutes

Independent: amounts of oil

Dependent: amounts of popped kernels

Controlled variables: Kernel brand, cooking time, popping time

Explanation:

Independent variables are what is changed or manipulated in the experiment or test, here the amount of oil is changed. The dependent variables rely upon the independent variables so they are what is influenced each time, here popped kernels are counted.

Typically, this is what is being tried for. Controlled factors are those that aren't being tried and are kept a similar each an ideal opportunity to ensure it doesn't change the result here Kernel brand, cooking time, popping time are controlled or unchanged.
